Opinta Bone Conduction Waterproof Swimming Headphones

Opinta Swimming Headphones are waterproof bone-conduction earbuds with IPX8 protection, 32GB onboard storage, Bluetooth 6.0, and long battery life designed for swimming, cycling, and running.

These sport-focused headphones combine open-ear bone conduction with true waterproof performance so you can listen while staying aware of your surroundings. Built-in 32GB memory lets you play music without a phone while an advanced Bluetooth 6.0 link handles land-based streaming. Lightweight and ergonomically shaped, the Opinta headphones are made to fit under a swim cap or behind-the-ear for all-day training and travel.

How do these headphones work underwater and on land?

On land, the Opinta headphones connect to phones and devices using Bluetooth 6.0 for calls and streaming. Underwater, Bluetooth cannot transmit, so the unit switches to MP3 mode and reads files from the internal 32GB memory for offline playback. This flexible design supports both active workouts and swim sessions.

• Bluetooth 6.0 for stable wireless connections up to about 10 meters on land.
• IPX8-rated sealing allows full submersion and use with swim caps and goggles.
• MP3 mode uses onboard 32GB storage for underwater listening.
• Supports MP3, WAV, WMA, M4A and FLAC audio formats for wide compatibility.

What safety and comfort features should I expect while exercising?

Opinta uses open-ear bone conduction so your ears remain uncovered, letting you hear environmental sounds like traffic or poolside instructions. The lightweight frame and ergonomic bend behind the ear offer a secure fit for running, cycling, or laps without ear canal pressure.

• Open-ear design keeps ear canals free and preserves ambient awareness.
• Bone conduction transmits sound through cheekbones for clear audio without in-ear buds.
• Low weight and flexible band fit under swim caps and behind ears comfortably.
• Built-in microphone enables clearer calls and voice assistant use on land.

How long will battery and storage last for workouts and travel?

The Opinta headphones recharge in about two hours and deliver extended performance for multi-session use. Expect up to 8 hours of continuous playback, plus roughly 110 hours of standby—enough for full training days or travel. With 32GB internal memory you can store thousands of tracks and leave your phone behind during swims.

• Full charge in roughly 2 hours using the magnetic charging connector.
• Up to 8 hours continuous playback per charge for sustained training.
• Approx. 110 hours of standby time for infrequent charging between trips.
• 32GB memory holds roughly 8,000 tracks depending on file size and format.

Can these headphones handle different activities and audio formats?

Yes — they are built for multi-sport use and accept many common audio file types. Use Bluetooth mode for calls and streaming outdoors, and switch to MP3 mode for reliable offline playback when swimming. The IPX8 rating and robust materials make them suitable for triathlon training, open-water swims, gym sessions, and daily commuting.

• Supports MP3, WAV, WMA, M4A and FLAC formats for high and compressed quality files.
• IPX8 waterproofing for submersion and heavy-sweat environments.
• Versatile fit for swimmers, cyclists, runners and general fitness.
• Magnetic charging reduces wear on ports and improves water resistance integrity.

Who is this for: Athletes and active commuters who need reliable audio both in and out of the water will find Opinta’s swimming headphones especially useful. They suit swimmers who want music during laps without earplugs, cyclists and runners who value ambient awareness, and travelers who need long battery life and on-device storage. If you want a lightweight, open-ear listening solution that performs underwater and supports standalone playback, these headphones are designed for you.
