This is a small unobtrusive headset that has excellent sound quality.  I like it better than the sound that comes from the earpiece on my cellphone.  People who hear me talking say that the sound quality is very good.  The only complaint that I get is when I try to talk in the car with the windows rolled down.  No biggie.  I just roll up the windows, problem solved. It is very easy to use and it was a cinch to pair up with my cell phone.  Super simple.  It can be paired up to three different phones.  A laptop using (Skype) Voip, a cell phone, and a regular home phone (like Vonage) that is bluetooth capable.  You just press a button 1, 2, or 3 times to connect to all your different equipment.

The battery lasts a good long time and you can charge it from you car, a computer, or from the wall.  All you need is included in the box.  It comes with everything.  No worries there.

All in all it's a good little unit.  It is inexpensive.  I am sure there are better headsets out there but for the money I don't think you can go wrong with this device.  I bought 4!  Now everyone in our house has one and all of us use them on a daily basis.  My wife runs hers completely out of battery power.  No wonder the cell phone bill is so high!! HA!!  If you get one I am sure you will be satisfied.
