Pros: I bought this headset to connect as a blue tooth head set for my PlayStation 3 console. The sound quality was outstanding and the mic input was awesome. I'm sure it's fine for phones but so a ps3 headset communicator it's tops.
Pros: Clarity of calls are good, volume operates as it needs too (I'm somewhat hard of hearing due to the Vietnam war).With all the others if I couldn't hear the caller I caught myself talking with a raised voice at times due to my hearing loss.
Cons: The ear support could be much longer so it wraps around the ear more. I Had a problem with it wanting to come off the ear now and again while working. And eventually broke it trying to adjust it over & over again to conform to my ear.
