The earpiece is comfortable. When it worked, I enjoyed using it. But, the Bluetooth connection to my Motorola Razr phone was spotty at best. In the middle of about 33% of my calls, I would get a "bluetooth connection weak" message from my phone, even though I was holding the phone in my hand, 2 feet from the phone. Disappointing performance to say the least.UPDATE: Turns out the problem was really with the phone, not the ear piece.
