It cancels noise best of any ear piece or headset. 16 hour talk time and I have walked at least 60 feet (staightline) from the headset. Blue Parrott claims 66, it may be possible
It's not small as most, but it out performs all and it's comfortable
Although the BP is large, it out perfroms so well, size does not matter. Three devices can be paired even a computer, but only one device can be connected. If you desire to use another device one has to be disconnected. HANDS DOWN TOPSSS of any bluetooth!
