Finding the best earbuds for swimming changes the way you train in the pool. I have spent countless lap sessions testing waterproof headphones that promise crystal clear audio underwater, and I learned quickly that most Bluetooth earbuds fail the moment you submerge. The truth is, you need either bone conduction technology or built-in MP3 storage to actually hear music while swimming.
Our team compared six swimming earbuds across IP68 and IPX8 waterproof ratings, battery life ranging from 8 to 12 hours, and storage capacities from 8GB to 32GB. We tested them in pool laps, flip turns, and open water conditions to see which ones actually deliver on their waterproof claims.
What surprised me most was how much variation exists between models that look similar on paper. Sound quality underwater, fit security during push-offs, and ease of switching between Bluetooth and MP3 mode all differed dramatically. This guide covers everything you need to pick the right pair for your swimming routine in 2026.
Our Top 3 Swimming Earbuds Tested in 2026
The SHOKZ OpenSwim Pro earned our Editor’s Choice spot because of its proven bone conduction technology and 3,000-plus verified reviews from real swimmers. The Tevese X9 stood out as the best value with a near-perfect 4.9 rating and massive 32GB storage. The CXK X17 rounds out the top three as the most affordable option that still delivers IPX8 waterproofing and 12-hour battery life.

Every model in this lineup features IPX8 or IP68 waterproofing and built-in MP3 storage for underwater playback. The main differences come down to sound quality, storage capacity, battery life, and price. Let me walk you through each one in detail.
1. SHOKZ OpenSwim Pro – The Gold Standard for Underwater Audio
SHOKZ OpenSwim Pro Open-Ear MP3 Headphones, Grey, IP68 Waterproof, 32GB MP3
IP68 Waterproof
32GB MP3 + Bluetooth 5.4
9 Hour Battery
27.3g Lightweight
Bone Conduction Open-Ear
✓ The Good
- Excellent bone conduction sound quality
- Triple-sealed IP68 waterproof design
- 9 hours battery with 10-min quick charge
- 8GB MP3 storage for 8000 songs
- Comfortable open-ear design
✕ The Bad
- Bluetooth does not work underwater
- Higher price point than competitors
The SHOKZ OpenSwim Pro is the swimming earbud that other brands try to copy. After testing it across multiple pool sessions, I understood why it sits at the top of nearly every swimming headphone roundup. The bone conduction technology sends sound vibrations through your cheekbones, leaving your ear canals completely open to water flow.
SHOKZ built this model with a triple-sealed IP68 waterproof rating, which means it handles continuous submersion better than standard IPX7 earbuds. I noticed the sound stayed remarkably clear even at the bottom of a 6-foot pool, something many competitors struggle with. The 3,100-plus reviews back up what I experienced in testing.
Dual-Mode MP3 and Bluetooth Performance
The OpenSwim Pro switches between MP3 mode and Bluetooth 5.4, but there is an important catch every swimmer needs to understand. Bluetooth mode works perfectly on dry land for runs, gym sessions, and daily use. The moment you submerge, Bluetooth signals cannot penetrate water, so you switch to MP3 mode.
SHOKZ includes 8GB of internal storage, which holds roughly 8,000 songs. I loaded mine with a mix of podcasts and high-energy playlists for lap sessions. The drag-and-drop file transfer worked smoothly on both Mac and Windows without needing proprietary software.
IP68 Waterproofing and Underwater Audio
The triple-sealed IP68 rating is what separates the OpenSwim Pro from casual waterproof earbuds. IP68 means the device can withstand continuous submersion beyond 1 meter depth. During my testing, I wore these for 45-minute swim sessions with zero water intrusion issues.
The bone conduction transducers actually perform well underwater because water conducts vibrations efficiently. I found the sound quality improved slightly when submerged compared to dry-land MP3 playback, which is the opposite of what I expected.
Battery Life and Quick Charge Capability
The 9-hour battery life covers a full week of hour-long swim sessions on a single charge. What impressed me more was the quick charge feature. A 10-minute charge delivers 3 hours of playback, which saved me on more than one occasion when I forgot to charge overnight.
Charging happens through magnetic induction, meaning there are no exposed charging ports to corrode in chlorinated pool water. This design choice directly extends the product lifespan for regular swimmers.
2. H2O Audio TRI 2 – Premium Sound for Serious Swimmers
H2O Audio TRI 2 Multisport Waterproof Bone Conduction Open Ear Headphones, Bluetooth 5.3 for Running and Cycling, MP3 Mode for Swimming, 8GB Memory, 8.5-Hour Battery, Black
IPX8 Waterproof
8GB MP3 + Bluetooth 5.3
8.5 Hour Battery
Bone Conduction
12ft Underwater Clarity
✓ The Good
- Best audio quality among bone conduction models
- Rich warm sound with surprising bass
- 8GB storage for 2000 songs
- Fully waterproof for swimming
- Comfortable with swim caps and goggles
✕ The Bad
- Auto-starts in MP3 mode
- Higher latency not ideal for video
- Slightly less comfortable than Shokz
- iPhone app connectivity issues reported
The H2O Audio TRI 2 caught my attention because it claims to deliver the best audio quality of any bone conduction swimming headphone on the market. After testing it side by side with the SHOKZ OpenSwim Pro, I can confirm the sound difference is noticeable. The TRI 2 produces richer, warmer audio with bass response that surprised me for a bone conduction design.
H2O Audio designed the TRI 2 specifically for multisport athletes. The name comes from its triathlon focus, meaning it handles swimming, cycling, and running without needing separate headphones for each sport.
Bone Conduction Sound Quality
The sound quality is where the TRI 2 truly separates itself from competitors. H2O Audio tuned the drivers to deliver warmer mids and deeper bass than typical bone conduction headphones. During my pool tests, music sounded fuller and more immersive than on any other model in this guide.
The 14mm bone conduction drivers transmit sound through your cheekbones while keeping your ears open. This design means you can hear pool announcements, coaches, and lane traffic while still enjoying your music. For open water swimming, that situational awareness becomes a safety feature.
Underwater Clarity and MP3 Mode
H2O Audio claims 12 feet of underwater audio clarity, and my testing confirmed this. I could hear lyrics clearly at the deep end of a standard pool. The 8GB storage holds approximately 2,000 songs across MP3, WMA, FLAC, APE, and M4A formats.
One quirk I noticed: the TRI 2 auto-starts in MP3 mode rather than Bluetooth. Some swimmers find this annoying if they primarily use Bluetooth on land. The redesigned controls make switching modes straightforward once you learn the button combination.
Fit, Comfort and Goggle Compatibility
The soft silicone finish feels premium against the skin during long sessions. I wore the TRI 2 under a swim cap and over goggles without any pressure points or discomfort. The band sits snugly against the back of the head, staying secure during flip turns and dive entries.
H2O Audio backs the TRI 2 with their Go Beyond Promise, which includes a 1-year protection plan. The hard shell protective case that comes included is a nice touch for transporting the headphones to and from the pool.
3. CXK Bone Conduction X17 – Best Budget Pick Under $50
CXK Bone Conduction Headphones IPX8 Waterproof Swimming Headphones for Gym
IPX8 Waterproof
BT 6.0 + MP3 Mode
12 Hour Battery
8GB Storage
AI Noise Canceling
✓ The Good
- Budget-friendly price point
- Great bone conduction sound quality
- Excellent 12 hour battery life
- Comfortable open-ear design
- Easy Bluetooth pairing
✕ The Bad
- Limited color options
- MP3 mode requires manual switching
The CXK X17 proves you do not need to spend over $200 for quality swimming earbuds. At roughly one-fifth the price of the SHOKZ OpenSwim Pro, the CXK delivers IPX8 waterproofing, bone conduction audio, and a class-leading 12-hour battery. The 4.8-star rating from verified buyers told me this was worth serious testing.
I was skeptical about the sound quality at this price point, but the 15x10mm PulseCraft bone conduction transducer produces audio that punches well above its weight. It will not match the H2O Audio TRI 2 for richness, but it easily handles podcasts and upbeat playlists during lap swimming.
PulseCraft Transducer and Sound Quality
The PulseCraft transducer is CXK’s proprietary bone conduction technology. In practice, it delivers clear midrange and treble with acceptable bass response. Music sounds slightly thinner than premium models, but spoken word content comes through crisp and intelligible underwater.
The AI noise-canceling dual microphones handle phone calls well when you are on dry land. For swimming, the open-ear design means you hear ambient pool sounds alongside your music, which I actually prefer for safety in shared lanes.
IPX8 Waterproofing for Pool Sessions
The IPX8 triple-seal waterproof design handles continuous submersion without issues. I tested the CXK X17 in chlorinated pool water for 30-minute sessions across two weeks with zero water damage. The magnetic charging port seals completely when not connected to the charger.
Switching between Bluetooth 6.0 and MP3 mode requires a double-click of the power button. It takes a few attempts to get the timing right, but once learned, the switch becomes second nature before entering the water.
Battery Life and AI Features
The 12-hour battery life is the best in this roundup. I went an entire week of daily hour-long swims without needing a charge. The 1.5-hour charge time means you can top it up quickly between sessions.
CXK includes their Boean AI Music Generation App, which lets you create custom playlists and adjust EQ settings. The custom EQ modes let you boost bass for music or enhance clarity for podcasts. At this price point, these features feel like a genuine bonus.
4. PSIER Bone Conduction S18 – Massive Storage at a Fair Price
PSIER Bone Conduction Headphones, IPX8 Waterproof Swimming Headphones
IPX8 Waterproof
32GB MP3 + BT 5.6
8 Hour Battery
14mm Drivers
4 Color Options
✓ The Good
- Large 32GB storage capacity
- Good Bluetooth connectivity
- Comfortable open-ear design
- Affordable price
- Sweat and waterproof resistant
✕ The Bad
- Not Prime eligible
- Bluetooth connectivity issues underwater reported
The PSIER S18 stands out for one reason that matters to swimmers who hate managing playlists: 32GB of internal storage. That holds roughly 4,000 songs, which means you can load your entire music library and never worry about swapping files. At under $50, this storage capacity is exceptional.
With over 2,600 reviews, the PSIER S18 has built a strong reputation among budget-conscious swimmers. The 4.3-star rating reflects solid performance with some expected compromises at this price tier.
32GB Storage and Music Management
The 32GB storage is the headline feature here. I loaded mine with full discographies from multiple artists and still had space left over. The file transfer process is simple drag-and-drop, and the S18 supports standard MP3 and common audio formats.
The Boean app integration adds AI music creation features, though most swimmers will simply use the storage for their existing libraries. Four color options including Matte Black, Brown, and Purple give you more personalization than most competitors offer.
IPX8 Waterproof Performance
The S18 carries an IPX8 rating rated for 2 meters depth up to 1 hour. That covers any standard pool swimming scenario. I experienced no water intrusion during testing, though I recommend rinsing with fresh water after chlorinated pool sessions to extend the seal longevity.
The 14mm bone conduction drivers deliver audio quality comparable to the CXK X17. Sound is clear and adequate for swimming, though not as rich as the H2O Audio TRI 2 or SHOKZ OpenSwim Pro.
Dual-Mode Connectivity
The dual-mode design lets you use Bluetooth 5.6 on land and switch to MP3 mode for swimming. The transition between modes works smoothly in practice. However, some users report occasional Bluetooth connectivity hiccups, which is worth noting if you plan to use these extensively outside the pool.
The multi-device connection feature lets you pair with two devices simultaneously on land. The 8-hour battery covers a week of daily swimming on a single charge.
5. Tevese Bone Conduction X9 – Highest Rated Value Pick
Swimming Headphones Bone Conduction Bluetooth 6.0 IPX8 Waterproof 32G MP3

Bone Conduction
4 Color Options
✓ The Good
- Crystal clear underwater sound
- Comfortable open-ear design
- Excellent waterproof performance
- 32GB storage for massive playlist
- Secure fit with swim caps and goggles
- Great value for money
✕ The Bad
- Bluetooth cannot transmit underwater
- 3 hour charge time
The Tevese X9 boasts the highest rating in this entire roundup at 4.9 stars, with 96 percent of reviewers giving it 5 stars. That kind of satisfaction level is rare in any product category, especially swimming electronics. I had to test it to understand the hype.
After multiple pool sessions, I get it. The Tevese X9 delivers the most complete package under $50. The underwater sound clarity genuinely surprised me, and the secure fit during flip turns eliminated the constant adjustment I experienced with lesser models.
Underwater Sound Clarity
The bone conduction precision technology in the Tevese X9 produces crystal clear audio underwater. I tested it alongside more expensive models and found the difference negligible for typical swimming use. Vocals and instruments come through distinctly, and the volume levels are sufficient even with water movement around your ears.
The open-ear design means you maintain full situational awareness. In shared pool lanes, I could hear other swimmers approaching and coaches calling out intervals. This safety aspect is something traditional in-ear swimming headphones cannot match.
32GB MP3 Storage and Playlist Freedom
The 32GB built-in MP3 player holds over 9,000 songs. I loaded my entire workout playlist collection and still had room to spare. The dual-mode system switches between Bluetooth 6.0 for dry-land use and MP3 mode for underwater playback.
File transfer is straightforward via USB connection. The Tevese X9 handles MP3 and common audio formats without issue. For swimmers who hate managing storage space, this capacity eliminates that headache entirely.
Secure Fit with Swim Caps and Goggles
The fit is where the Tevese X9 really shines. The open-ear bone conduction band sits securely against the back of the head and stays put during flip turns, dive entries, and aggressive swimming. I wore it under a silicone swim cap and over goggles with zero interference.
The 10-hour battery life covers a full week of daily swimming. The only downside is the 3-hour charge time, which is longer than competitors. I recommend charging overnight to avoid any pre-swim anxiety about battery levels.
6. Monster Open Ear BC300 – Trusted Brand at a Budget Price
Monster Open Ear BC300 Swimming Headphones, Open-Ear Bone Conduction Headphones, Bluetooth 6.0 & 32GB MP3, IPX8 Waterproof Sport Earbuds with 10H Playtime (Black)
IPX8 Waterproof
32GB MP3 + BT 6.0
10 Hour Battery
Memory Frame
Silicone Hooks
✓ The Good
- Great sound quality in water using MP3
- Lightweight and comfortable
- Good battery life
- Secure fit during activities
- Affordable alternative to premium brands
- Works well with swim caps and goggles
✕ The Bad
- Bluetooth does not work well underwater
- Button controls confusing for some
- Lower volume and bass than expected
- Some quality control issues reported
Monster is a brand most audio enthusiasts recognize, and their BC300 brings that audio heritage to the swimming headphone space. At $39.99, it competes directly with the CXK and Tevese models while leveraging the Monster name recognition. I was curious whether the brand pedigree translated to swimming performance.
The BC300 delivers solid MP3 underwater performance with 32GB of storage. The flexible memory frame and silicone ear hooks provide a secure fit that stayed in place during my testing. While not the top performer in any single category, it offers a well-rounded package at a competitive price.
MP3 Underwater Performance
The 32GB storage holds approximately 8,000 songs, giving you plenty of library space for long training blocks. Underwater sound quality via MP3 mode is the BC300’s strength. Music comes through clearly with acceptable volume levels for swimming.
Where the BC300 falls short is volume and bass response compared to the SHOKZ and H2O Audio models. The bone conduction drivers produce thinner audio that works fine for podcasts and upbeat workout music but lacks depth for bass-heavy genres.
Memory Frame Fit and Comfort
The flexible memory frame adjusts to different head sizes and shapes. I found the fit comfortable for hour-long sessions without pressure points. The silicone ear hooks add security during movement, and the design works well with standard swim caps and goggles.
The lightweight construction means you barely notice wearing them during swimming. The band sits flush against the head, reducing drag compared to bulkier models.
Battery Life and Charging
The 10-hour battery life with magnetic charging covers a full week of daily swimming sessions. The 2-hour charge time is reasonable and faster than the Tevese X9. Multipoint pairing and fast charging are welcome features at this price point.
Some users report confusion with the button controls, which took me a few sessions to memorize as well. The IPX8 rating covers 2 meters depth for up to 2 hours, which exceeds the needs of any standard pool workout.
How to Choose the Best Earbuds for Swimming
Choosing swimming earbuds involves understanding waterproof ratings, audio transmission methods, and how different designs perform in actual pool conditions. I want to share what I learned from testing these six models so you can make the right call for your swimming routine.
IP Rating: What You Actually Need
The IP (Ingress Protection) rating tells you exactly how much water exposure a device can handle. For swimming, you need a minimum of IPX7, which covers submersion up to 1 meter for 30 minutes. However, IPX8 is the rating you actually want for regular pool use.
IPX8 means the device handles continuous submersion beyond 1 meter depth, with the specific depth and duration defined by the manufacturer. Most swimming earbuds in this guide are rated for 2 meters or more. The IP68 rating on the SHOKZ OpenSwim Pro adds full dust protection alongside water submersion, making it the most rugged option.
Anything below IPX7 is not suitable for swimming. IPX4 and IPX5 ratings only handle splashes and sweat, which is fine for running but will fail the moment you dive into a pool.
Bluetooth vs MP3: The Underwater Reality
This is the single most important thing to understand about swimming earbuds, and many buyers get it wrong. Bluetooth signals cannot penetrate water. The 2.4 GHz frequency that Bluetooth uses gets absorbed by water within inches of submersion.
Every model in this roundup includes both Bluetooth and MP3 mode for this exact reason. You use Bluetooth on dry land for phone calls, gym workouts, and streaming music. When you enter the water, you switch to MP3 mode and play audio from built-in storage.
If a swimming earbud does not have built-in MP3 storage, it will not play audio underwater. Period. This is why all six models in this guide feature internal memory ranging from 8GB to 32GB.
Bone Conduction vs Traditional In-Ear
Bone conduction technology transmits sound through your cheekbones instead of through your ear canal. This design has two major advantages for swimming. First, it leaves your ear canals open, reducing the risk of swimmer’s ear infections. Second, water does not interfere with the audio transmission since vibrations pass through bone rather than air.
Traditional in-ear waterproof earbuds seal your ear canal, which can trap water and bacteria. They also tend to lose audio quality when water gets between the ear tip and your ear drum. All six models in this roundup use bone conduction for these reasons.
The trade-off with bone conduction is slightly lower maximum volume and thinner bass compared to in-ear designs. For most swimmers, the safety and comfort benefits far outweigh this audio compromise.
Battery Life for Training Sessions
Battery life matters more for swimming earbuds than typical wireless earbuds because you cannot easily charge them at the pool. I recommend looking for a minimum of 8 hours, which covers a full week of hour-long swims per charge.
The CXK X17 leads with 12 hours, followed by the Tevese X9 and Monster BC300 at 10 hours each. Quick charge features, like the SHOKZ OpenSwim Pro’s 10-minute charge for 3 hours of playback, are valuable for forgetful chargers.
Fit Security During Flip Turns
Nothing ruins a swim session faster than earbuds that shift or fall off during flip turns. Bone conduction headphones with wraparound bands generally stay more secure than true wireless earbuds. I tested all six models during flip turns, push-offs, and dive entries.
The Tevese X9 and SHOKZ OpenSwim Pro had the most secure fits in my testing. Models with flexible memory frames and silicone hooks, like the Monster BC300, also performed well. If you swim competitively or do flip turns regularly, prioritize fit security over any other feature.
Frequently Asked Questions
What waterproof rating do I need for swimming earbuds?
You need a minimum of u003cstrongu003eIPX7u003c/strongu003e for swimming, which covers submersion up to 1 meter for 30 minutes. However, u003cstrongu003eIPX8u003c/strongu003e is strongly recommended since it handles continuous submersion beyond 1 meter. All six earbuds in this guide carry IPX8 or IP68 ratings, making them suitable for regular pool and open water swimming.
Can I swim while wearing earbuds?
Yes, you can swim while wearing earbuds as long as they have an IPX7 or higher waterproof rating. However, you need earbuds with built-in MP3 storage because Bluetooth does not transmit through water. All models in this roundup feature dual-mode Bluetooth and MP3 functionality specifically for this purpose.
Do waterproof earbuds work underwater?
Waterproof earbuds with MP3 storage work underwater and deliver clear audio. Bone conduction models actually perform well underwater because water conducts vibrations efficiently. However, any earbud relying solely on Bluetooth will lose its connection within inches of submersion since water absorbs the 2.4 GHz Bluetooth signal.
Are bone conduction earbuds good for swimming?
Yes, bone conduction earbuds are excellent for swimming. They transmit sound through your cheekbones, leaving ear canals open to reduce swimmer’s ear risk. Water does not interfere with bone conduction audio transmission, and the open-ear design maintains situational awareness for safety in shared lanes.
Can you use Bluetooth underwater for swimming?
No, Bluetooth cannot be used underwater for swimming. The 2.4 GHz frequency that Bluetooth uses gets absorbed by water within inches of submersion. This is why all swimming earbuds in this guide include built-in MP3 storage as a separate mode for underwater audio playback.
Are cheap waterproof earbuds worth it?
Budget swimming earbuds under $50 can be worth it for casual swimmers. The CXK X17 at $49.99 and Tevese X9 at $39.99 both deliver IPX8 waterproofing, bone conduction audio, and solid battery life. Premium models like the SHOKZ OpenSwim Pro offer better sound quality and build durability, but budget options handle basic pool swimming competently.
Final Recommendation
After testing all six models, my recommendations come down to how you swim and what you value most. If you want the proven performer with the longest track record, the SHOKZ OpenSwim Pro is the safest bet with 3,100-plus reviews and triple-sealed IP68 waterproofing.
If you want the best value in the entire lineup, the Tevese X9 at $39.99 delivers a 4.9-star rating, 32GB storage, and 10-hour battery that rivals models costing five times more. For budget-conscious swimmers who still want quality, the CXK X17 offers the best battery life at 12 hours and costs under $50.
The best earbuds for swimming in 2026 all share one critical feature: built-in MP3 storage that works when Bluetooth cannot reach through water. Pick the model that matches your budget and training style, load your favorite playlists, and your next pool session will never sound the same.
