Bone Conduction Swimming Training System – 7-Channel IPX8

Coach Your Swimmers Like a Pro – Without Missing a Beat

The Bone Conduction Swimming Training System (Model H907) is the ultimate tool for swim coaches who need real-time, crystal-clear communication with their swimmers — even underwater. Using advanced bone conduction technology paired with a 7-channel FM transmitter, coaches can broadcast instructions up to 120–200 metres across a pool, while swimmers hear every word through fully waterproof (IPX8) bone conduction earphones rated to 10 metres depth. No more waving from the poolside or shouting over the noise — just seamless, professional coaching.

Frequently Asked Questions

Q: Can one coach use this bone conduction swimming system to instruct multiple swimmers at once?

A: Yes! Each FM frequency channel supports an unlimited number of swimmers simultaneously. The coach's transmitter broadcasts to all earphones set to the same frequency, making large group lessons easy and efficient.

Q: How many coaches and groups can use the system in the same pool without signal interference?

A: Up to 12 groups can operate simultaneously in the same pool. Each coach selects a different frequency channel, ensuring completely separate, interference-free communication with their respective student group.

Q: Is this swimming training earphone system truly waterproof?

A: Yes. The bone conduction earphones carry an IPX8 waterproof rating, meaning they can withstand submersion to 10 metres depth — well beyond what most training drills require. The earphones can also receive audio signals up to 1 metre underwater.

Q: How long does the battery last on a single charge, and how do I charge the earphones?

A: The earphones offer 4–6 hours of continuous use on a full charge. Charging takes approximately 2 hours using the included magnetic charging cable. After swimming, always wipe the magnetic charging port clean and dry before connecting the charger.

Q: Can a coach speak privately to a single student using this bone conduction swim training system?

A: Yes. The coach and the individual student can both switch to the same selected frequency for private communication. This allows targeted instruction without broadcasting to the entire group.
