Nice sound and Comfy 
It have what I was looking for: Small size, nice quality sound with no echo, and a long battery life.
But something that I was misunderstood for some reason is that the connects to the computer or a car outlet is just for charging. You can’t use it while charging. Hope this helped
BlueAnt X3 
Great little product for the price. This was my first bluetooth headset, so I did a lot of research and was a little unsure if it would work with my phone, the blackberry 8830 world phone, but happily it did work. In my opinion the only button that is really usable while it is in your ear is the answer call/hangup button, IE the big circular button in the middle. The rest are two small to operate blindly. Luckily it is pretty easy to mute a call from my phone, so it doesn’t matter that I can’t easily do it from the ear piece. I tried the ear piece in several noisy locations, an Airport, driving in the car, and in a quiet office, and all times the other party said they heard me just fine, and I heard them just fine. It also works great with the voice dialing feature of my phone. I don’t even use the ear hook, and it stays in just fine, note though I’m no athelete, so you wont find me playing basketball with the ear piece in. In the end I am very happy with my purchase, I wanted a low priced bluetooth earpiece that worked with my phone, that would answer calls, hangup calls, mute calls if it was too loud where I was, and that did some level of background noise cancellation for a newbie introductory price, and that had a relatively good standby and talk time, and except for having to activate mute from my phone I got what I wanted.
Well worth the money!
This works very well. It is lightweight and always works. The only problem is the earbud is a little larger but it should bother most people because instead of putting it in your ear it sets on top of your ear. The feature of connecting 3 phones is awesome.
Good but not great. 
The X3 pairs easily with my Palm but the one trouble I have is that it does not fit snugly in my ear and thus I have a hard time hearing people on it.
Hard to keep on
The call clarity is wonderful and the fact that you can charge the unit using the wall plug or USB right out of the box is great. The battery life is good as well. The weight is also a plus since it’s barely noticeable once you have it on.
There are two problems that I had with this headset though. The first is the fact that it was hard to get the headset on quickly. Even after months it took some time to get the headset on correctly. My other bluetooth was much easier to put on.
The second problem is default rubber cover for the speaker can move a bit so sometimes you have to play with the placement of the cover to get it to sit correctly in your ear.
