This was my first Bluetooth Headset, so I wasn't sure what to expect.
After charging the device (took only 30 min or so), connecting it to my mobile was no problem at all. Just switch it on, switch on bluetooth on the phone and voilà.. :) Automatic reconnection if a call comes in, or if you press the button.
The earpiece is quite big and can become uncomfortable after a while, if your ears are small. Other than that it stays where it's supposed to.
The sound quality is ok. Connection isn't the greatest. Works fine with the phone in front of you or somewhere in sight. But it crackles a lot if the mobile is in your pocket or handbag, especially when the battery is low.
I had to set the volume to minimum (unless I'm in traffic). When you press the button the beep is quite loud even on minimal volume. Volume buttons are easy to access, even while wearing it.
All in all I'm not too impressed, but it's an ok product.
