Really comfortable and manageable waterproof cordless external (e.bone conduction) headset with IPX8 water protection.

Don't use the headphones in sauna or sea water. 
These headphones are designed to be used with MP3s in the pool. Since bluetooth connection does not work after 10m distance and under water.

New technology - Waterproof headphones that can be carried around the swimming pool. You can listen to music while you swim and even dive. Function down to a depth of 3 meters.

The battery that gives the ability to listen for approx. 5 hours per charge.

The phone is therefore unnecessary in swimming and other sports. It is possible to go out in the rain without any problems and phone calls. Water, sweat and other wetting cause no problems.

No cables - no tangles and no fuss.

The headphones let you know with a speaking voice who is calling and so you do not have to look at the phone or answer without knowing who is on the line. Also let them know the status of batteries etc.

Very good sound quality through HD audio system.
