I brought this headset to link to my phone and Beeline 2 so I could hear directions. The lining on my Schuberth would not allow the clamp fitting but the adhesive fixing works extremely well. Bluetooth is easy to pair and has been stable on all rides so far. A couple of five hour trips proved that battery life is good too. Sound quality and volume are both excellent with earplugs and the volume control is easy to use. Well chuffed with a quality product at a good price.
