Nanajorwa Bone Conduction Swimming Headphones with 32GB MP3

Nanajorwa Bone Conduction Headphones are open-ear, IPX8-rated sports headphones with a built-in 32GB MP3 player for listening underwater, plus Bluetooth 6.0 for dry-land streaming.

These wraparound bone conduction headphones combine waterproof durability for pool and open-water sessions with a lightweight, stable fit for running, cycling, and gym use. Because Bluetooth signals don’t travel well underwater, the integrated 32GB MP3 storage lets you load music and spoken-word files directly onto the headset. On land, Bluetooth 6.0 provides low-latency wireless playback and hands-free calls. The design prioritizes situational awareness by leaving the ear canal open while delivering sound through bone conduction.

How do I use the built-in MP3 player while swimming?

Switch the headphones to MP3 mode and navigate stored files using the onboard controls. Files are played from internal storage without any wireless connection, so audio remains uninterrupted during submersion.

• Load MP3/compatible audio files to the 32GB internal memory via USB.
• Use physical buttons to play, pause, skip tracks, and adjust volume.
• IPX8 rating protects the electronics for submersion up to 2 meters.
• Magnetic charging seals the port to reduce water ingress risk.

Will these stay secure during intense workouts?

The wraparound, open-ear frame is engineered to sit firmly behind the head and over the cheekbones, minimizing bounce during repetitive movement. At just 26 grams, the headphones are light enough to remain comfortable through long sessions while staying in place for swimming laps, running, and cycling.

• Flexible, ergonomic frame contours to head shape for a snug fit.
• Low weight (26 g) reduces slippage and neck strain.
• Open-ear layout avoids in-ear seal issues that can loosen during activity.
• Stable during cardio, pool training, and strength circuits.

Can I use Bluetooth and MP3 modes interchangeably?

Yes — Bluetooth 6.0 handles wireless streaming and calls when you’re out of the water, while the onboard MP3 player provides reliable playback during swims. Switch modes depending on environment and battery needs.

• Bluetooth 6.0 for low-latency streaming, calls, and pairing with devices.
• 32GB internal storage for offline audio during submerged use.
• Simple mode switching using the physical control cluster.
• Up to 10 hours playtime at moderate volume on a full charge.

How long does the battery last and how do I recharge?

Expect up to 10 hours of playback at around half volume — enough for long training sessions or multiple workouts between charges. A magnetic charging connector speeds recharging and reduces exposure of ports to water and sweat.

• Approx. 10 hours playback at 50% volume.
• Full recharge in under 2 hours with magnetic charging cable.
• Charging design helps protect sealed electronics from moisture.
• Battery life varies with volume, mode (Bluetooth vs MP3), and usage patterns.

Who is this for? These Nanajorwa bone conduction headphones are aimed at swimmers, triathletes, and active outdoor exercisers who want music or coaching audio without blocking ambient sound. They suit anyone who needs reliable underwater playback for lap training and a secure, comfortable headset for running, cycling, and gym use. Choose them if you prioritize situational awareness, waterproof performance, and the convenience of built-in MP3 storage alongside modern Bluetooth connectivity.
