The Jabra BT8010 is a nice and innovative product. It's the Bluetooth headset of choice if you want the option of listening to music in stereo from your cell phone and you aren't interested in making a fashion statement. It has functionality that isn't in any other Bluetooth head set.It's not perfect though.The sound is good for both music and voice. It isn't as good as the "ear muff" types I've used but better than other convertible types. The jog dial volume control is much better than the push button of other headsets.The controls are easy to use and intuitive once you get familiar with them. When listening to music you can skip forward but not jump back.I like the hard switch to turn the device on or off.The innovative features really sets this headset apart from the rest. The display clearly provides status information and the caller ID lets you know who's calling. Of course you need to remove it from your ear to read the display. The call list allows you to dial the number of up to 15 recent calls. The built in 30 entry phone book is quite handy.The battery life is pretty much as advertised, which is good.There are a couple of things that keep me from giving it 5 stars.The minor things, it don't look stylish at all and you can't jump backwards to previous songs. The major issue is the built in equalizer simply does not work at any setting other than neutral.
