Plantronics Discovery™ 640 Bluetooth Headset

It works, and works well. I rarely am 30ft away from my cell phone, but I am often 10-12 feet, and it works perfect. One button touch and the phone is answered and I am able to talk.
Charging: I hate having separate plug-in chargers. The AAA pen style pocket charger is GENIUS and works well. I can now charge the device anywhere, anytime and not worry about a wall outlet.
I can hear people fine, and they can hear me. No one even knows I am using a headset - and this is important because I often have used other devices and everyone eventually asks me, "Are you using a headset?"
I find it hard to even really notice that I am wearing it, and the fact that it comes with three different sized ear gels makes it easy to find the right fit. I have never used the over ear clip because it fits so well into my ear.
