Best Waterproof Swim Headphones for 2025 (Tested by a World Championship Swimmer)

Swimming in silence is a thing of the past. Waterproof headphones have become one of the most requested training accessories among competitive and fitness swimmers — and for good reason. Music and audio cues improve motivation, pacing, and focus during long sets. I've been swimming competitively since age 8, competed at the 2008 and 2012 U.S. Olympic Trials, won a silver medal at the 2008 FINA World Championships in the 4x100 medley relay, and currently hold the American Record in the 100 yard butterfly for ages 35–39. I've used waterproof headphones throughout my Masters training and know what separates reliable options from overpriced frustrations.

I've tested waterproof headphones across open water sessions, lap pool training, and kick sets. The best options balance audio quality, secure fit, battery life, and true waterproofing. Here are my top 5 picks for 2025.

#1 FINIS Duo Underwater MP3 Player — Best Overall (~$100–120)

The FINIS Duo is the gold standard for competitive swimmers. It uses bone conduction technology — the audio transmits through your cheekbones rather than into your ear canal — which means it stays secure under goggles and works perfectly in the pool. Storage is onboard (no Bluetooth required underwater), so you load music directly and swim. Battery life is solid at around 7 hours. The audio quality is surprisingly good for a bone conduction device. I've personally used FINIS products for years and trust the brand's engineering for swim-specific gear.

#2 Shokz OpenSwim Bone Conduction Headphones — Best Runner-Up (~$130–150)

The Shokz OpenSwim (formerly AfterShokz Xtrainerz) is built specifically for swimming. Like the FINIS Duo, it uses bone conduction and onboard MP3 storage — no Bluetooth needed underwater. It holds up to 4GB of music, has an 8-hour battery life, and is rated IP68 waterproof to 2 meters. The fit is secure and comfortable for long sessions. The audio quality is slightly better than the FINIS Duo in my experience, though the price point is higher. A top pick for swimmers who want premium bone conduction audio.

#3 H2O Audio Tri Multi-Sport Headphones — Best Value (~$50–60)

H2O Audio makes one of the best budget options for swimmers who want earbuds rather than bone conduction. The Tri Multi-Sport Headphones are IPX8 rated to 3.6 meters, have a secure fit with swim-specific ear tips, and work with most waterproof MP3 players and cases. Sound quality is good for the price — noticeably better bass response than bone conduction options.

#4 Deboer Swim Training Kit — My Training Brand

As a member of Deboer Swim's Team Elite program, I train in Deboer suits and gear daily. Deboer is an elite performance swimwear brand trusted by top competitive swimmers. Their training suits are designed for durability and performance, holding up through heavy yardage while maintaining compression and comfort. If you're serious about your swim training, Deboer is worth trying.

#5 Sony NW-WS413 Walkman Waterproof MP3 Player — Best for Advanced Swimmers (~$80–90)

The Sony NW-WS413 is a wearable all-in-one waterproof MP3 player — the headphones and player are one unit that wraps around your head. It's IPX5/8 rated, has 4GB of onboard storage, and delivers 12 hours of battery life. The audio quality is noticeably better than bone conduction options, and the secure wrap-around design stays put during aggressive swimming. A premium choice for experienced swimmers who want the best audio quality underwater.
