KOPIDOE Bone Conduction Swimming Headphones 32GB MP3

KOPIDOE Bone Conduction Swimming Headphones are open-ear, IPX8 waterproof earbuds with built-in 32GB MP3 storage and Bluetooth 5.4 for swimming, running, and cycling.

These headphones combine bone conduction audio with a waterproof, sport-ready design so you can listen without in-ear buds. With an internal 32GB music player, you can play thousands of tracks while you swim; Bluetooth 5.4 offers fast wireless pairing on land. The open-ear fit keeps your ear canals free and maintains environmental awareness during outdoor activities.

How do these headphones work while swimming?

The KOPIDOE uses bone conduction to transmit sound through the cheekbones, letting you hear audio without inserting earbuds. For submerged use, switch the unit to MP3 mode and play music directly from the internal 32GB storage since Bluetooth signals don’t pass well underwater. The IPX8 rating supports immersion up to 3 meters, so they’re designed for laps and open-water sessions.

• Switch to MP3 mode before entering water for uninterrupted playback.
• Store up to about 9,000 songs on the built-in 32GB memory.
• IPX8 waterproofing withstands prolonged submersion up to 3 meters.
• Bone conduction transmits sound without blocking ear canals.

How reliable is the wireless connection on land?

On dry land, Bluetooth 5.4 delivers fast pairing and more stable transmission up to roughly 33 feet. The headphones support dual-device connections so you can be paired to a phone and tablet at once and switch with minimal interruption. Keep in mind Bluetooth is intended for air use only — not underwater.

• Bluetooth 5.4 for improved speed and range up to about 10 meters (33 feet).
• Simultaneous connection to two devices for easy switching.
• Use Bluetooth for calls, streaming, and outdoor workouts; MP3 mode for underwater.
• Lightweight design reduces dropouts during movement and exercise.

What battery life and charging features should I expect?

The headphones have a 200 mAh battery that supports roughly 8 hours of continuous music or talk time and about 72 hours standby. A magnetic waterproof charging connector fully replenishes the battery in approximately two hours, helping you return to training quickly. The long runtime covers multiple workouts or a full day of outdoor activity.

• About 8 hours of continuous playback per full charge.
• 200 mAh battery capacity with ~2 hour recharge via magnetic waterproof port.
• 72 hours typical standby time between charges.
• Magnetic connector preserves waterproof seal and simplifies charging.

How comfortable and safe is the open-ear design?

The open-ear bone conduction format keeps your ear canals clear and reduces in-ear pressure while letting ambient sound through for situational awareness. Ergonomic shaping and a lightweight frame keep the headset stable during running, cycling, and swimming movements. This design supports both safety and comfort for outdoor training.

• Open-ear fit maintains awareness of traffic and surroundings.
• Ergonomic, lightweight frame stays put during active use.
• No in-ear tips to cause pressure or block ear canals.
• Suitable for multisport use: pool laps, road runs, and rides.

Who is this for: KOPIDOE bone conduction headphones suit swimmers who want onboard music without a phone, triathletes transitioning between water and land, runners and cyclists who need to hear traffic, and fitness lovers who prefer an open-ear listening experience. They’re ideal for anyone wanting a waterproof, standalone audio option with both Bluetooth convenience on land and a dedicated MP3 player for underwater sessions.
