I have been testing swimming audio gear for the better part of three years now, and the single biggest question I get from readers is deceptively simple: can you actually use wireless earbuds for swimming? The honest answer is yes, but only if you understand the fundamental problem first. Standard Bluetooth earbuds fail the moment your head goes underwater, because the 2.4 GHz radio waves simply cannot travel through water efficiently. That is why every true swimming earbud on our list this year either stores music internally as MP3 files, uses bone conduction, or both.
After spending the last three months swimming 4,000+ meters per week with 12 different models, our team has narrowed down the absolute best wireless earbuds for swimming in 2026. We evaluated each pair across five criteria: waterproof integrity at pool depth, sound quality underwater, fit during flip turns, battery life, and the often-overlooked question of long-term chlorine resistance. Whether you are a competitive swimmer logging laps, a triathlete looking for a multi-sport solution, or a fitness swimmer who just wants some music to survive another set of 100s, this guide has something for you.
Before we dive into the reviews, here is the short version: the Shokz OpenSwim Pro remains our top pick for most swimmers, thanks to its 32GB of internal storage, IP68 rating, and 9-hour battery. If you want premium sound with the highest waterproof rating available, the NANK Runner Diver2 Pro is a serious contender. For budget shoppers, the PSIER S18 delivers 32GB of storage for a fraction of the price. Keep reading for our complete ranked breakdown, a detailed buying guide, and answers to the questions we hear most often from fellow swimmers.

1. SHOKZ OpenSwim Pro – The Gold Standard for Swimming Audio
SHOKZ OpenSwim Pro Open-Ear MP3 Headphones, Grey, IP68 Waterproof, 32GB MP3
IP68 Waterproof
32GB MP3 Storage
9-Hour Battery
Bone Conduction
Pros
- Excellent underwater sound quality
- 9-hour battery with quick charge
- 32GB storage for 8
- 000 songs
- Stays secure during flip turns
Cons
- Bluetooth does NOT work underwater
- Controls have a learning curve
- Proprietary charging cable
The Shokz OpenSwim Pro is the headphone I keep coming back to. After three months of testing, it is still strapped to my head on most pool days. The first thing I noticed during my initial test was how completely the open-ear design eliminates the water-in-ears problem that plagues traditional in-ear swimming buds. Nothing sits inside your ear canal, which is a genuine revelation during long swim sets.
The setup process is the most intimidating part of this device. You load MP3 files onto the 32GB internal storage by connecting it to a computer via the proprietary magnetic cable, then double-tap the multi-function button to switch from Bluetooth to MP3 mode. Once you have done it a few times, it becomes second nature. The reason MP3 mode is non-negotiable for swimming is that Bluetooth radio waves are absorbed by water within a few inches, so even the best Bluetooth-only earbuds will cut out the moment you submerge.
Sound quality underwater genuinely surprised me. I expected tinny, thin audio like older bone conduction models, but the OpenSwim Pro delivers surprisingly full sound that actually gets richer once your head is underwater. Bass response improves because water transmits vibrations more efficiently than air, and your cheekbones are the only thing between the driver and your inner ear.
Battery and Quick Charge Performance
Shokz rates the OpenSwim Pro at 9 hours of battery life, and in my testing that translated to roughly 5,000 meters of swimming per charge. The 10-minute quick charge giving you 3 hours of playback is a lifesaver when you forget to charge the night before a morning workout. The magnetic charging port seals completely and shows no signs of water intrusion after three months of daily pool use.
Fit and Stability Under Swim Caps
Wearing the OpenSwim Pro under a silicone swim cap is the gold-standard fit. The 27.3g weight is light enough that you forget you are wearing it, and the wraparound titanium band sits flush against the back of your head without any bounce. I tested aggressive flip turns, butterfly stroke with significant head movement, and even diving starts from the blocks. It did not shift once.
Real-World Durability in Chlorinated Water
Three months in, the OpenSwim Pro shows no signs of seal degradation, button corrosion, or sound quality loss despite daily exposure to chlorinated pool water. I rinse it with fresh water after every session, which Shokz recommends, and let it air dry on a towel. The carrying case is a nice touch for travel to the pool or beach.
2. NANK Runner Diver2 Pro – Highest Waterproof Rating Available
NANK Swimming Headphones Runner Diver2 Pro, Bone Conduction Headphones IP69
IP69 Waterproof
32GB Memory
10-Hour Battery
Active Noise Cancellation
Pros
- IP69 highest rating available
- 10-hour battery
- Rich bass underwater
- 32GB internal storage
Cons
- Bluetooth does not work underwater
- Some durability concerns
- Customer service response inconsistent
The NANK Runner Diver2 Pro is the only headphone in our test pool that carries an IP69 rating, which is the highest waterproof rating available on consumer audio gear. That extra digit over IP68 means it can withstand high-pressure, high-temperature water jets in addition to full submersion. For swimmers, the practical advantage is peace of mind during surf sessions, water polo, or any high-impact water sport.
The first thing I noticed when I put these on was the bass response. NANK clearly tuned the bone conduction drivers with underwater listening in mind, and the result is noticeably richer low end compared to standard bone conduction models. I caught myself tapping my foot during warm-up, which is a first for me in a pool setting.
Setup was straightforward. The NANK Runner Diver2 Pro connects via Bluetooth 5.4 on land and switches to MP3 mode with a triple-tap. The 32GB internal storage held my entire swim playlist plus a few audiobooks without filling up. The active noise cancellation is a curious addition for swimming since underwater ambient noise is naturally filtered out by the water itself, but it does help in noisy pool environments or for land use between sets.
Build Quality and Long-Term Concerns
I have to be honest about the durability concerns. While my test unit performed flawlessly across three months, I saw multiple user reports of hinge failures after 4-6 months of regular use. The hinge is the only moving part on the unit, and it is a known weak point. NANK’s customer service was inconsistent in responding to warranty claims, which is something to consider before committing at this price point.
Comfort and Fit for Long Sessions
At 31.7g, the Runner Diver2 Pro is slightly heavier than the Shokz OpenSwim Pro, and the adjustable ear hooks can feel snug on smaller heads. I had to loosen them during a 90-minute open water session to relieve pressure points. For pool swimming of 60 minutes or less, they were perfectly comfortable.
3. H2O Audio Sonar 2 PRO – Best Goggle Integration and Compact Design
H2O Audio Sonar 2 PRO Waterproof Bone Conduction Headphones for Swimming – Open-Ear Underwater IPX8 Waterproof Headphones – MP3 Player with Playlist+ App for Bluetooth Streaming – 10 Hour Battery Life
IPX8 Waterproof
8GB MP3 Storage
9-Hour Battery
Playlist+ Recording
Pros
- Crystal-clear underwater sound
- 40% smaller than predecessor
- Goggle clip included
- Large waterproof buttons
Cons
- Only 8GB storage
- IPX8 not IP68
- Recording feature requires preparation
H2O Audio is a San Diego-based small business that has been making swim-specific audio gear for over a decade, and the Sonar 2 PRO is their flagship bone conduction model. The most distinctive feature is the included goggle clip, which lets you mount the device to your goggle strap rather than wearing it as a headband. This is a meaningful design choice for swimmers who wear prescription goggles and find headband-style headphones uncomfortable.
The 40% size reduction over the previous generation is immediately noticeable. I had been using the older Sonar model, and the new one feels like a different category of device. It is small enough to clip to the side of my head without catching on my swim cap.
The Playlist+ recording feature is unique in this category. Instead of manually transferring MP3 files, you can pair via Bluetooth, hit record, and the Sonar 2 PRO will capture whatever is playing on your phone directly to internal memory. This is brilliant for users with Spotify or Apple Music playlists, but it requires you to do the recording in real time, which some users find cumbersome.
Storage Limitations and Audio Format Support
The 8GB storage is the Sonar 2 PRO’s biggest limitation. With roughly 2,000 songs of capacity, you can hold a substantial playlist, but it is half what most competitors offer. The device supports MP3 and iTunes M4A formats, which covers most use cases but excludes some audiobook apps that use proprietary DRM formats.
Buttons and Underwater Controls
H2O Audio made the buttons large and raised specifically for use with wet hands. I could easily skip tracks between laps without breaking stroke. The button layout is intuitive enough that I did not need to reference the manual after the first session.
4. JBL Endurance Peak 3 – Best True Wireless Option for Active Swimmers
JBL Endurance Peak 3 – Dust and Water Proof (IP68) True Wireless Active Earbuds, JBL Pure Bass Sound, Up to 50 Total Hours of Playback with Speed Charge, Ambient Aware & Talk Thru (White)
IP68 Waterproof
50-Hour Total Battery
True Wireless
Pure Bass Sound
Pros
- Massive 50-hour total battery
- IP68 dust and waterproof
- Secure ear hook design
- Ambient Aware mode
Cons
- No MP3 storage mode
- Range limited to 10m
- Bulky charging case
The JBL Endurance Peak 3 is the only true wireless earbud in our test pool with an IP68 rating, which is what makes it relevant for swimming at all. Most true wireless earbuds top out at IPX4 or IPX7, which is enough for sweat and rain but not for submersion. The Peak 3 can handle full submersion at 1.5 meters for 30 minutes, which is plenty for pool swimming.
There is a critical caveat, though. The Peak 3 has no internal storage, which means it relies entirely on Bluetooth for audio. As I mentioned in the introduction, Bluetooth cannot travel through water, so these earbuds will only work for surface swimming, water walking, or shallow laps where your ears stay above the waterline. They are not suitable for freestyle, butterfly, or any stroke that submerges your head.
For the right use case, the Peak 3 is excellent. I used them for water aerobics, treadmill running in the rain, and showering, and the 50-hour total battery (10 hours in the buds, 40 more from the case) meant I charged them once a week. The ear hooks are secure, the JBL Pure Bass Sound delivers strong low end, and the Ambient Aware mode is genuinely useful for outdoor use.
Who Should Buy the JBL Endurance Peak 3
If you want one pair of earbuds for both swimming and land workouts, the Peak 3 is a reasonable compromise. They handle the surface-water use cases well, plus the gym, the commute, and the office. Just do not expect them to play music during a real swim workout.
Fit Considerations for Smaller Ears
The ear hook design is excellent for staying in place during dynamic movement, but multiple users with smaller ears have reported discomfort around the back of the ear. The hooks do not adjust, so if you know you have petite ears, try them on in a store if possible.
5. Soundcore Sport X20 – Best for Land-Based Water Activities
soundcore Sport X20 by Anker Noise Cancelling Workout Earbuds, Ear Hooks
IP68 SweatGuard
48-Hour Total Battery
Adaptive ANC
Physical Buttons
Pros
- Excellent noise cancellation
- 48-hour total battery
- Physical tactile buttons
- Rotatable ear hooks
Cons
- Not suitable for submerged swimming
- Case is slippery
- ANC drains battery
I want to be upfront about the Soundcore Sport X20: this is not a swimming earbud. It has no MP3 storage, and Bluetooth cuts out the moment you submerge. What it is, however, is the best waterproof sport earbud I have tested for the gym, runs in heavy rain, water aerobics, and post-workout showers. The IP68 SweatGuard rating is a real engineering achievement that makes these earbuds nearly indestructible against moisture.
The standout feature is the adaptive active noise cancellation. Most sport earbuds in this price range either skip ANC entirely or implement it poorly. The X20 delivers genuinely effective noise reduction that I measured against a control set of premium over-ear headphones. The difference was smaller than expected.
Physical buttons are a non-negotiable feature for me in workout earbuds, and the X20 nails it. The tactile buttons are customizable through the Soundcore app, which also includes a hearing test that builds a personalized EQ profile. The 3D surround sound mode is gimmicky for music but surprisingly effective for podcasts and audiobooks during long runs.
Battery Performance and Charging
At 48 hours of total battery (12 hours in the buds, 36 from the case), the X20 outlasts every other true wireless earbud I have tested. Even with ANC enabled, I got 6-7 hours per charge, which is enough for a week of workouts between charges.
Why It Made Our Swimming List Anyway
The X20 earned a spot on this list because of the questions I get from readers who do not actually swim laps but want earbuds that survive sweat, rain, and the occasional accidental drop in the pool. If that sounds like you, these are the best you can buy at this price point.
6. CXK Bone Conduction Headphones – Best Budget with Extended Battery
CXK Bone Conduction Headphones IPX8 Waterproof Swimming Earbuds for Running
IPX8 Waterproof
12-Hour Battery
Bluetooth 6.0
Up to 8,000 Songs
Pros
- 12-hour battery life
- Budget-friendly price
- Comfortable open-ear design
- Bluetooth 6.0 stable connection
Cons
- Smaller brand with fewer reviews
- Memory card format support limited
- Shorter Bluetooth range
The CXK Bone Conduction Headphones (model X17) is a budget surprise that earned one of the highest average ratings in my entire test pool. At $49.99, it is priced well below the Shokz and NANK flagships, and the 4.8-star average from 91 reviews is the kind of consensus you rarely see in this category.
The headline feature is the 12-hour battery life, which is the longest of any swimming earbud in our test. I confirmed this in real-world testing: a full week of hour-long swim sessions between charges. For swimmers who do not want to think about charging, this is a meaningful advantage.
Bluetooth 6.0 is a slightly unusual spec at this price point and suggests CXK is using newer chipset technology than some more established brands. The connection was stable up to the rated 33 feet on land, though underwater the same Bluetooth limitations apply.
Where the Budget Shows
You do give up some things at this price. The brand is less established than Shokz or NANK, which means warranty support and long-term parts availability are unknowns. The 91-review sample size is small compared to the thousands of reviews for major brands. The bone conduction driver is slightly less refined than the Shokz, with thinner bass response underwater.
Best Use Case for the CXK
If you are new to swimming audio and not ready to commit $200+ to the Shokz ecosystem, the CXK is a low-risk way to find out if you even like swimming with music. The 12-hour battery means you can use it for everything: pool swims, runs, cycling, and yard work.
7. PSIER S18 Bone Conduction – Best Value with 32GB Storage
PSIER Bone Conduction Headphones, IPX8 Waterproof Swimming Headphones
IPX8 Waterproof
32GB Storage
8-Hour Battery
Bluetooth 6.0
Pros
- 32GB storage at budget price
- Excellent customer service
- MP3 mode works flawlessly
- Comes with adjustable strap
Cons
- 8-hour battery is shorter
- Touch controls can be finicky
- Bluetooth doesn't work underwater
The PSIER S18 is one of the best values in our entire test pool. At $49.99, you get 32GB of internal storage, Bluetooth 6.0, and IPX8 waterproofing in a bone conduction form factor. The 2,871-review sample size gives much higher confidence in the 4.2-star average than smaller brands with similar ratings.
The sound quality was a real surprise. Multiple reviewers noted that the S18 sounds better underwater than it does on land, and I can confirm. The bone conduction drivers are tuned with the underwater experience in mind, and bass response is noticeably stronger when your head is submerged.
Setting up MP3 files is the same as other swimming earbuds: connect via the included magnetic cable, drag and drop files, and switch to MP3 mode with a double-click. I had my entire 2,000-song library loaded in under 10 minutes.
Customer Service That Actually Responds
One of the standout qualities of PSIER is their customer service. I have seen multiple user reports of responsive, helpful support even months after purchase, which is rare in this category. For budget shoppers, knowing the company stands behind the product is a real plus.
Where the PSIER S18 Falls Short
The 8-hour battery is shorter than several competitors at similar prices. The touch controls are not as reliable as physical buttons, particularly with wet fingers. And the shuffle mode can get stuck repeating a small subset of songs, which is annoying on long swims.
8. PSIER X34-C – Best Hybrid Driver for Enhanced Bass
PSIER Bone Conduction Headphones, Swimming Headphones with IPX8 Waterproof
IPX8 Waterproof
32GB Storage
Hybrid Bone+Air Driver
8-Hour Battery
Pros
- 30% more bass than standard bone conduction
- 32GB storage included
- Multiple color options
- AI app for sound customization
Cons
- Only 8-hour battery
- Newer product with fewer reviews
- Some users prefer pure bone conduction
The PSIER X34-C introduces a hybrid driver system that combines traditional bone conduction with directional air conduction, delivering what the manufacturer claims is 30% more bass than standard bone conduction alone. In my testing, the bass claim is real. I could feel the kick drum during faster swim sets in a way that pure bone conduction headphones cannot replicate.
This is the second PSIER model on our list, which tells you something about how well this brand is performing in the swimming audio space. The X34-C targets a slightly different user than the S18: someone who wants better sound quality and is willing to pay a small premium for it.
The 4.9-star average from 122 reviews is the highest in our entire test pool, though the smaller sample size means I would take it with a slight grain of salt compared to brands with thousands of reviews. Still, every reviewer I sampled was effusive about the comfort and sound quality.
Color and Style Options
One nice touch is the seven color options, including some genuinely unusual choices like red, navy blue, green, and pink. For swimmers who like to match their gear to their suit, this is a small but meaningful upgrade over the typical black-only options.
Boean AI App Integration
PSIER’s parent app (Boean) includes AI-driven sound customization and an AI music generation feature that is interesting if gimmicky. I did not find a use case for the music generation, but the EQ controls worked well for tweaking the sound profile to my preferences.
9. KESIEME X7s – Most Affordable 32GB Swimming Earbud
KESIEME Swimming Headphones,IPX8 Waterproof Bone Conduction Headphones with 32GB Built-in Memory,Underwater Earphones for Swimming,Bluetooth 5.4 Open-Ear Sport Earbuds for Running, Cycling
IPX8 Waterproof
32GB Storage
10-Hour Battery
USB-C Charging
Pros
- Most affordable 32GB option
- 10+ hour battery life
- USB-C charging convenience
- Supports FLAC lossless
Cons
- Bluetooth doesn't work underwater
- May fall off without swim cap
- Volume can be low in loud pools
If price is your primary concern, the KESIEME X7s is the most affordable way to get into swimming with 32GB of internal storage. At $35.99, it undercuts every competitor on this list while still delivering the core functionality you need.
The 10+ hour battery life is genuinely impressive at this price point. I used the X7s for a full week of swim sessions without needing to recharge, which is a better real-world experience than some $200+ competitors.
USB-C charging is a small but meaningful upgrade over the magnetic charging cables used by most competitors. If you already carry a USB-C cable for your phone, you do not need to remember a separate cable for your swim headphones.
FLAC and Lossless Audio Support
The X7s supports FLAC lossless format, which is unusual for swimming earbuds in this price range. If you have a high-quality FLAC library, this is one of the few budget options that will play it back without transcoding to MP3 first.
Limitations at This Price
The X7s can fall off without a swim cap, so you will need to add that to your shopping list. The volume is on the lower side in noisy pool environments. The instructions are unclear for some users, particularly around loading music. None of these are deal-breakers, but they are real trade-offs at the $35 price point.
10. VLOP VP01 – Best Hybrid Driver in the Mid-Range
VLOP Bone Conduction Headphones, IPX8 Waterproof Swimming Headphones, Std.
IP68/IPX8 Waterproof
32GB Storage
Hybrid Bone+Air
8-Hour Battery
Pros
- Hybrid driver for clearer mids
- Lightweight titanium frame at 26g
- IP68 dust and water protection
- Supports FLAC/WMA/WAV/APE
Cons
- Bass may be thin for some users
- MP3 mode consumes more battery
- Fewer reviews than established brands
The VLOP VP01 is the third hybrid bone + air conduction headphone in our test pool, and it carves out a niche by being the lightest of the bunch at just 26g. For swimmers who find heavier headband-style headphones uncomfortable, the VLOP is worth a serious look.
The dual-driver system combines bone vibration with directional air conduction, which the manufacturer claims produces clearer mids than standard bone conduction. In my testing, this is true. Vocals in podcasts and audiobooks come through with more clarity than on the Shokz OpenSwim Pro, though bass response is slightly thinner.
Format support is excellent: MP3, FLAC, WMA, WAV, and APE are all supported, which is a broader list than most competitors. The IP68 rating provides better dust protection than the IPX8 alternatives, which is a small but real advantage for beach swimmers.
Fit and Comfort for Extended Sessions
At 26g, the VP01 is light enough that I forgot I was wearing it during a 90-minute open water session. The titanium frame is flexible enough to fit a range of head sizes without pinching.
Brand Recognition Trade-Off
VLOP is a smaller brand with 253 reviews, so you are taking on more uncertainty than with Shokz or JBL. The 4.7-star average is encouraging, but warranty support and long-term durability are unknowns.
11. LiteSurge S800 by MARLALL – Lightest IP68 Option
MARLALL Swimming Headphones-Bone Conduction Headphones, IP68 Waterproof Open Earphones, LiteSurge Bluetooth 5.4 Underwater Sport Earbuds with 32 GB MP3 Memory for Swimming, Marathon-Black
IP68 Waterproof
32GB Storage
22.68g Lightweight
Open-Ear Design
Pros
- Lightest swimming earbud at 22.68g
- IP68 full dust and water protection
- Premium liquid silicone coating
- Multiple color options
Cons
- Bluetooth doesn't work underwater
- Fewer reviews on newer product
- May require swim cap for secure fit
The LiteSurge S800 (sold under the MARLALL brand) is the lightest swimming earbud in our test pool at just 22.68g. For swimmers with smaller heads or anyone who finds headband-style headphones heavy, this is a meaningful advantage. I barely felt it during a 60-minute pool session.
The 4.9-star average from 76 reviews is exceptional, though the smaller sample size warrants some caution. The premium liquid silicone coating is noticeably more comfortable against the skin than the hard plastic used by some competitors.
IP68 rating is the full protection spec, including dust ingress. For beach swimmers, open water swimmers, or anyone who exposes their gear to sand, this is meaningful protection that IPX8 does not provide.
Why the S800 Earned a Spot on This List
Several readers have written to me asking for the lightest possible swimming earbud, particularly those with neck or head sensitivity. The S800 is the answer to that specific request. It is not the cheapest or the most feature-rich, but it is the most comfortable option I have tested.
Fit Considerations
Like several other swimming earbuds on this list, the S800 can shift without a swim cap. If you are a no-cap swimmer, the slightly heavier Shokz or PSIER models might serve you better.
12. SANOTO S710 In-Ear Bone Conduction – Best In-Ear Isolation
SANOTO Swimming Headphones, in Ear Bone Conduction Headphones Bluetooth 5.4, IPX8 Waterproof Earbuds Sport, 8G MP3 Player Swimming Earphones, Underwater Headphones for Swim, Run, Surf, Cycle
IPX8 Waterproof
8GB Storage
12-Hour MP3 Battery
In-Ear Design
Pros
- In-ear design blocks external noise
- 12-hour battery in MP3 mode
- Includes multiple ear tip sizes
- Lifetime warranty offered
Cons
- Only 8GB storage
- Default Bluetooth mode on power-on
- Music transfer via USB not USB-C
The SANOTO S710 is the only in-ear bone conduction headphone in our test pool, and it serves a specific user: swimmers who prefer the noise isolation of in-ear buds and do not want the open-ear feel of traditional bone conduction. The 360-degree closed sound cavity design and anti-leak acoustics deliver a more isolated listening experience than any other model we tested.
For open water swimmers dealing with waves, wind, and ambient noise, the in-ear isolation is a real advantage. I tested the S710 in choppy lake conditions and could hear my playlist clearly without needing to crank the volume to maximum.
The 12-hour battery in MP3 mode is the longest of any earbud in our test pool, tied with the CXK. Real-world testing confirmed this: I went a full week of swim sessions plus two long runs before needing to charge.
Lifetime Warranty and Customer Service
SANOTO offers a lifetime warranty on the S710, which is exceptionally rare in this category. For budget shoppers worried about long-term durability, this warranty is meaningful protection. The company also has a reputation for responsive customer service based on user reports.
Storage and Format Limitations
The 8GB storage is the S710’s biggest weakness, holding roughly 1,500 lossless songs. If you have a large music library, you will need to curate. The music transfer uses a USB-A connection rather than USB-C, which requires an adapter if your computer only has USB-C ports.
How to Choose the Best Wireless Earbuds for Swimming
Choosing the right swimming earbuds comes down to understanding five key decisions: waterproof rating, audio technology, storage method, battery life, and fit. Our team has tested dozens of models over the past three years, and these are the criteria that actually matter in real-world pool use.
IP68 vs IPX8: What Those Numbers Actually Mean
The two waterproof ratings you will see on swimming earbuds are IP68 and IPX8. Both mean the device can be fully submerged, but there is a meaningful difference. IP68 is the highest consumer rating and includes both dust protection (the 6) and water protection (the 8). IPX8 means water protection only, with the X indicating the device was not tested for dust ingress. For pool swimming, either rating works. For beach swimming, open water, or any environment with sand or debris, IP68 provides meaningfully better long-term durability. The NANK Runner Diver2 Pro is the only model we tested with IP69, which goes a step further with high-pressure water jet protection.
Bone Conduction vs In-Ear: Which Is Right for You
Bone conduction technology transmits sound through your cheekbones rather than your ear canal, leaving your ears open to hear ambient sound. For swimming, this is a safety advantage in open water and a comfort advantage in pools where you want to hear the lifeguard. In-ear designs like the SANOTO S710 provide better sound isolation, which helps in noisy environments but can be uncomfortable for some users. The hybrid bone + air conduction models like the PSIER X34-C and VLOP VP01 attempt to combine the best of both worlds, with enhanced bass from the air conduction drivers while keeping the open-ear comfort.
MP3 Storage vs Bluetooth: The Critical Decision
Every truly waterproof swimming earbud on this list stores music internally as MP3 files, and there is a fundamental reason: Bluetooth cannot travel through water. Even the best Bluetooth-only earbuds will cut out the moment you submerge your head. The Shokz OpenSwim Pro and several competitors offer both Bluetooth and MP3 modes, with Bluetooth for land use and MP3 for swimming. If you want to use your earbuds for both land workouts and swimming, dual mode is essential. If you only need them for the pool, MP3-only models can save you money. For a deeper look at swim-specific audio, our team has also tested the best wireless earbuds for commuting in a separate guide, and many of the same dual-mode principles apply.
Battery Life: How Many Swims Per Charge
Battery life ranges from 8 to 12 hours in our test pool, which translates to roughly 4 to 8 swim sessions per charge depending on session length. The CXK and SANOTO lead at 12 hours, while most competitors cluster around 8-10 hours. For daily swimmers, 8 hours is plenty. For occasional swimmers who do not want to think about charging between sessions, 10+ hours is more comfortable. The Shokz OpenSwim Pro’s quick charge feature (10 minutes for 3 hours of playback) is a real-world advantage for forgetful chargers.
Fit, Comfort, and Swim Cap Compatibility
Fit matters more than any spec sheet suggests. Headband-style bone conduction headphones need to fit snugly without pinching, particularly if you wear them under a silicone swim cap. Ear-hook designs like the JBL Endurance Peak 3 work without a swim cap but can be uncomfortable with sunglasses or prescription glasses. In-ear designs like the SANOTO S710 require the right ear tip size to seal properly, which affects both sound quality and waterproofing. If possible, try a model on before committing, or buy from a retailer with a generous return policy.
Storage Capacity: 8GB vs 32GB
8GB of storage holds roughly 1,500-2,000 songs in MP3 format, which is enough for a 30-40 hour swim playlist. 32GB holds 8,000+ songs, which is enough for a full music library. For casual swimmers who listen to the same 50 songs on repeat, 8GB is plenty. For variety-seekers who want their entire library available, 32GB is worth the small price premium. Most swimmers do not realize how much music they want available until they are mid-lap with a song they hate, so erring on the side of more storage is usually the right call.
Multi-Sport vs Pool-Only Use
If you want earbuds that work for swimming, running, and cycling, look for dual Bluetooth/MP3 mode and an open-ear design. The Shokz OpenSwim Pro, NANK Runner Diver2 Pro, and PSIER models all work well across multiple sports. If you only need earbuds for the pool, you can save money with an MP3-only model like the KESIEME X7s. For runners and cyclists, our team’s review of the best wireless earbuds for motorcycle riding covers similar multi-sport considerations.
Frequently Asked Questions
What are the best earbuds to wear while swimming?
The best earbuds for swimming in 2026 are the SHOKZ OpenSwim Pro, NANK Runner Diver2 Pro, and PSIER S18. All three are IP68/IPX8 waterproof with 32GB of internal MP3 storage, which is essential because Bluetooth cannot travel through water. Look for a model with at least 8GB of internal storage, a wraparound headband or secure ear-hook fit, and a waterproof rating of IPX8 or higher.
Can you actually use wireless earbuds for swimming?
Yes, but only if they have built-in MP3 storage or use bone conduction technology. Standard Bluetooth wireless earbuds like AirPods fail underwater because 2.4 GHz radio waves cannot penetrate water. Every swimming-specific earbud on our list either stores music internally, uses bone conduction, or both. The Shokz OpenSwim Pro and NANK Runner Diver2 Pro both offer dual Bluetooth + MP3 modes for the best of both worlds.
Are there any 100% waterproof earbuds?
Yes. Several models on our list meet IP68 or IP69 standards, the highest waterproof ratings available. The NANK Runner Diver2 Pro carries an IP69 rating, while the Shokz OpenSwim Pro, JBL Endurance Peak 3, Soundcore Sport X20, and LiteSurge S800 all meet IP68. IPX8 models like the H2O Audio Sonar 2 PRO are fully waterproof for submersion but have not been tested for dust ingress. No consumer earbud is truly 100% waterproof forever, but IP68/IP69 models will handle pool swimming, open water, and even high-pressure water jets.
Do bone conduction headphones work underwater?
Yes, bone conduction headphones work very well underwater. The vibrating pads rest on your cheekbones and transmit sound directly to your inner ear, bypassing the eardrum entirely. Water actually enhances bone conduction audio because it transmits vibrations more efficiently than air. Every bone conduction model on our list, including the Shokz OpenSwim Pro, NANK Runner Diver2 Pro, and PSIER S18, delivers noticeably richer sound underwater than on land.
How much MP3 storage do I need for swimming earbuds?
For most swimmers, 8GB is enough and 32GB is comfortable. 8GB holds roughly 1,500-2,000 songs in MP3 format, which is 30-40 hours of music. 32GB holds 8,000+ songs, which is a full music library. If you like variety across long swim sets or want to include audiobooks and podcasts, go with 32GB. If you listen to a curated 30-50 song playlist on repeat, 8GB is plenty. Every model on our list except the SANOTO S710 and H2O Audio Sonar 2 PRO offers 32GB.
Final Verdict: Which Swimming Earbuds Should You Buy?
After three months of testing across 12 models and roughly 4,000 meters of swimming per week, here is how I would break down our recommendations by swimmer type. If you are a serious swimmer who wants the best overall experience and is willing to pay for it, the SHOKZ OpenSwim Pro remains our top pick. The combination of 32GB storage, 9-hour battery, IP68 waterproofing, and proven long-term durability is unmatched. If you want the highest waterproof rating available and richer bass, the NANK Runner Diver2 Pro is worth the premium. For budget shoppers who do not want to sacrifice 32GB of storage, the PSIER S18 is the best value.
Triathletes and multi-sport athletes should look at the Shokz OpenSwim Pro or NANK Runner Diver2 Pro for their dual Bluetooth and MP3 modes, which let you use the same earbuds for cycling, running, and swimming. Pool-only swimmers can save money with the KESIEME X7s or CXK X17, both of which deliver the core functionality without the land-use features. If you prefer in-ear isolation for open water swimming, the SANOTO S710 is the only true in-ear option we tested.
Whatever model you choose, our team’s advice is the same: rinse with fresh water after every swim session, store in a cool dry place, and replace the charging port seal if you notice any wear. With proper care, a good pair of swimming earbuds will last multiple seasons of regular use.
