Plantronics is a world leader in ear-piece peripherals. They manufacture every imaginable headsets from telephone to gaming. The Explorer 330 fits the bill to supplement a bluetooth cellphone and its ease of use and functionality is way superior to a lot of bluetooth headphones out there. I have had mine for about 2 years now and has always worked great. Pairing is not a problem for this headset, once the pairing is recorded in the phone, there are no quirks about pairing it when you need to use it. Distance-wise, it does not conform to the 33ft maximum, but on a personal note, I hardly part the headset with the phone in that distance so it hardly matters according to my intended use. Overall happy with this headset as it has exceeded my expectations to great lengths!
