i've had this bluetooth headset for about 6 months now. i can wear this thing all day. it's really comfortable and secure. you don't have that feeling that is going to fall off when you turn your head. i can only compare this to two other headsets i've had which is the moto hs820 and one of the logitech's. the moto had horrible outgoing, where the other person could barely hear me. the logitech was great, but it was really bulky and heavy on my ear. both suffered from that unsecure feeling.the v510 has great inbound and outbound sound quality, but using the headset while there is a breeze renders it useless unless you use the included foam attachment that goes over the mic. there is a newer version of this same bluetooth headset that is the same name and model, but it is black and silver instead. it appears the mic area was redesigned to help with the wind problem without the use of the foam attachment. you guys might want to check that version out instead.
