Jabra extreme2 bluetooth works great! Bought it elsewhere for $20 or so and never regret it. I love the long battery life that lasts all day at work.

Overall the mounting options are really really realllllly awful- the button position is very idiotic really. Very disappointing. The cost to ups this to the uk is $80.

The battery lasts at least 2-3 days before it needs recharging. It keeps disconnecting when you move from one room to another without the phone. I get a low batter warning at 3hrs 40 minutes and 20 minutes later it shuts itself off.

The microphone pickup was hit an miss. The audio is fine - it's the microphone that's the problem. As long as the speaker isn't speaking the unit transmits noise as usual.

Only came with one ear bud. No ear clip. Not comfortable in the ear. If i have to look at my phone to see who's calling, that defeats half the purpose of the earpiece.
