How we chose the best swimming headphones
Swimming presents challenges that a rain-resistant running earbud cannot handle. We prioritized models rated IPX8 or IP68 and designed by their manufacturers for sustained underwater use. Every pick also has onboard storage because Bluetooth signals travel poorly through water; even a phone sitting at the edge of the pool will cut out when the headphones are submerged.
We compared storage capacity, battery life, fit, controls and file-transfer process. We also considered whether each model works outside the pool. Bluetooth is valuable for running and commuting, but it should be treated as a dry-land bonus rather than an underwater playback method.
Best for most swimmers: Shokz OpenSwim Pro
OpenSwim Pro is the most complete one-headset solution here. Its 32GB player carries a large offline library, while Bluetooth mode handles podcasts, calls and streaming on land. The open-ear frame remains stable during push-offs and does not require watertight earbud seals.
It suits swimmers who want one headset for the pool, gym and running. The trade-offs are its relatively high price and the leaner bass typical of bone conduction. You must also switch to MP3 mode before entering the water.
A simpler value: Shokz OpenSwim
The standard OpenSwim strips away Bluetooth and concentrates on lap swimming. Its 4GB capacity is modest by current standards but still accommodates hundreds of compressed tracks. Physical buttons are easier to locate with wet hands than touch controls, and the neckband works comfortably with most caps and goggles.
Choose it if you already own separate everyday earbuds and do not need audio streaming. Its proprietary charging and transfer cradle is less convenient than USB-C, so losing the cable can interrupt training.
Best for podcasts: H2O Audio TRI 2 PRO
H2O Audio’s TRI 2 PRO is notable for Playlist+, a feature designed to load streaming audio into the headset for later offline playback. That makes it more practical for spoken-word listeners who do not maintain a folder of purchased MP3 files. It also offers Bluetooth for above-water workouts.
The capture workflow requires more setup than dragging standard audio files onto storage, and underwater bone-conduction sound is optimized more for rhythm and speech intelligibility than audiophile detail. Nevertheless, it fills a useful niche for podcast-heavy training sessions.
Best sealed in-ear option: Sony NW-WS623
Sony’s NW-WS623 combines a compact Walkman with sealed earbuds. Compared with open-ear designs, it can deliver fuller bass and stronger isolation when the correct swimming tips form a secure seal. It is also rated for saltwater use, making it attractive for open-water swimmers.
Fit is more personal than with a bone-conduction band, however, and the older Micro-USB-era charging system feels dated. Swimmers should rinse it thoroughly after saltwater or chlorinated-pool sessions.
Best for dedicated lap training: FINIS Duo
The FINIS Duo clips directly to goggle straps and rests against the cheekbones. This arrangement eliminates a neckband and keeps the controls close to the temple. Its underwater-focused bone-conduction presentation becomes noticeably clearer once submerged.
The Duo makes the most sense for swimmers who want a pool-only player. It has no Bluetooth, and its seven-hour battery and 4GB storage trail newer multipurpose models. Correct placement also depends on wearing compatible goggles.
