Your phone will ring in your ear at quite some distance, but to actually connect and talk to someone using the headset remotely, you needed to be within 10-15 feet of the phone.To avoid too much static, you really needed to be within 5-10 feet of your phone. But even if you had the ohone in your hand/holster, there was some static.The volume was OK, I bought volumecontrol software to boost the volume, but it made it scratchier. The speaker is just too tinny. I am hard of hearing though, so no fair there.Comfort. OK. After about 20 minutes you notice it, then you forget about it, and you take it off 2 hours later and your ear hurts a bit. Normal I guess.Battery time was gerat, both talk and standby.Pairing was easy with my treo.good charging connection (stem plug) and quick charging.It's good for the price, but I think you can do better. I am looking at the Plantronics Voyager 510.
