Perfect for your outdoor adventures, this lightweight, stable and comfortable helmet naturally stays put, even when you're practising on technical terrain.
Designed around bone conductiontechnology, these headphones rest on your jawbone, unlike In-ear headphones. It leaves your ear canal free so you can listen to your music without masking the ambient noise that's vital to Belayer's security.
What's more, the Long 8-hour battery life means you can enjoy your favourite artist's new album to the full while listening to the birds around you. They are fully charged in 90 minutes , and a simple 20-minute charge will give you 3 hours extra listening time!
You can use them in all weathers, thanks to their IP67 Standard , as they are water and rain resistant.
If you want to listen to both your music and the sounds around you, while enjoying unrivalled comfort during your activities, opt for the Active.
