This is the first and only Bluetooth I purchased. The reception and microphone is good indoors and out. I could never get it to feel comfortable on my ear. The answer, on/off button is in a very awkward position. The ear piece kept loosing connection with my phone (Samsung A900) and it was depleting the phone battery very fast, so by the end of the day I had no battery left, even if I used the ear piece for only two hours a day. I stopped using it after two months.
