I've read all the reviews and I have to say that the volume level is fine...after I read the manual and set the buttons to raise it. Perhaps this is where some are having their problems. The first time I used it the volume was low for my liking, but after setting the buttons as required and adjusting I could hear as well with the headset as I can with the V3 in hand up to my ear.True the unit is very light. I've forgotten it was on more than once. With small ears I too feel like it might fall off however short of shaking my head with vigor it stays on fine. Sure a 'firmer feel' would give me more of a sense of of security but the looser fit works perfectly with sunglasses.The controls are super easy. Tap a call on or hold for a refusal. Set up was a breeze as well.Nobody I've spoken with has complained with their reception of my calls...in fact some couldn't tell if I was on the headset or not.I've had no problems with road noise or background pick up. As a matter of fact in a very windy walk to the office the mic didn't pick up the noise...the call went on without a missed beat.Overall I'm very pleased with this BT headset. The price is right, the comfort is very good and the operation is, to me, excellent.
