Comfortable and functionable

I love the concept of bluetooth earpieces to save me from having to either hold the phone or have it on speaker.  Rarely am I able to find one that easily pairs with my device and works well.  So far, this ear piece has done both.
The sound and microphone are very clear.  I haven't had a single phone call where the person could tell I was using a connected device and not the actual phone.  I have also not had any issues where the phone and device unexpectedly unpaired.  This was a huge issue with some of the others I tried.
The ear piece itself is also very comfortable.  I can usually only tolerate ear pieces for short periods of time.
Typically, I only put them in for phone calls, and then promptly remove them.  I don't have that issue with this one and often leave it in once the phone call has finished.
