I bought them on another site (for payment in 3, I would like amazon finally offers us the service), I am very happy. Pairing with iPhone 6 works fine, clicking long on the phone button I can even order siri distance (telephone in my room, ear ear, I can call someone from afar by asking Siri to dial ), the sound is okay, insulation too. Anyway, I am pleased of this product and I recommend it.
Edict March 20, 2015: after 6 months of use I'm still delighted with this product that will induce me to go to extra large smartphone. My parties hear me very well and helmet still works very well.
