Wantek® BC3 Pro Bluetooth Waterproof Headphones for Swimming – Bone Conduction MP3 Player for Lap & Open Water Training

Bone conduction headphones bypass the ear canal entirely. They transmit sound vibrations directly through your cheekbones to the cochlea (inner ear). Underwater, they switch to onboard MP3 storage rather than Bluetooth — because Bluetooth radio signals cannot travel through water. Load music onto the device via USB before your swim, press the mode button to switch to MP3 mode, and audio plays clearly at any depth within the IP68 rating. The Wantek BC3 Pro's 32GB storage holds approximately 8,000 songs.

No — and no swimming headphone can use Bluetooth while submerged. Bluetooth (2.4 GHz radio) cannot penetrate water. The Wantek BC3 Pro handles this correctly: 32GB of onboard MP3 storage is used underwater, and full Bluetooth 5.3 connectivity is available for running, cycling, or gym training on land. Switch modes with a double-tap of the power button. This dual-mode design is what sets it apart from Shokz OpenSwim, which has no Bluetooth at all.

IP68 is more comprehensive than IPX8. The first digit (6) in IP68 certifies dust-tightness — no particles enter the device. The second digit (8) certifies continuous submersion beyond 1 meter. IPX8 certifies submersion but the "X" means dust protection was never tested. For pool environments, which expose headphones to fine grit, sand, and sunscreen particles in addition to water, IP68 is the correct minimum standard.

Connect the BC3 Pro to any computer using the included magnetic charging cable. It appears as a USB storage drive. Drag and drop music files (MP3, FLAC, AAC supported) into the music folder. 32GB holds approximately 5,000–8,000 songs. Eject the drive, disconnect, and double-tap the power button to switch from Bluetooth to MP3 playback mode. No app, no subscription, no account required.

Yes. The BC3 Pro's behind-the-head titanium band sits below the goggle strap line and under a standard silicone or latex cap. The transducer pads rest on the cheekbones in front of the ears, clear of most goggle frame designs. The fit range accommodates head circumferences of 4.3 to 5.5 inches. Triathlon and open-water swimmers regularly use this setup with no fit conflicts reported.

The Wantek BC3 Pro delivers up to 9 hours of continuous playback per charge. A full charge takes approximately 1.5 hours via the magnetic cable. A 5-minute quick charge provides approximately 30 minutes of additional playback — a useful rescue before a morning swim session. This compares favourably to the Shokz OpenSwim (8 hours) at less than one-quarter the price.

Yes. The BC3 Pro is designed for both pool and saltwater open-water swimming. The titanium frame is chemically inert — unaffected by chlorine, saltwater, or UV. After ocean or saltwater swimming, rinse with fresh water and air-dry before charging. This is standard practice for all waterproof electronics regardless of IP rating.

The Wantek BC3 Pro and Shokz OpenSwim share the same core technology (IP68 bone conduction, MP3 storage) but differ in two key areas: the BC3 Pro adds Bluetooth 5.3 for out-of-water multi-use (the Shokz OpenSwim has no Bluetooth), and the BC3 Pro's 32GB storage is 4× the OpenSwim's 8GB (4GB usable). The BC3 Pro retails at $39.99 versus $149–$180 for the OpenSwim. For swimmers who also run or cycle with their headphones, the BC3 Pro's Bluetooth mode eliminates the need for a separate device.

They often provide a more comfortable listening solution for swimmers with ear conditions or hearing loss.
