I just used it for the first time this morning for about one hour in my car & it was great!! Voice clarity was exellent. It was also very comfortable & fit snuggly to my ear.The best part was the freedom from the wire that always pulled at me everytime I moved my head.I also appreciate the price which was way more reasonable than the Jabra model (which cost almost as much as some phones). A headset should not cost $60 - $80 unless you really have money to burn. The M2500 cost me $37 here on Amazon not including a $20 rebate from cingular. Final Total Cost $17. Not bad at all...Thanx Plantronics,From one happy customer...
