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.
Pros: This is a great little device for the money, I got it for my birthday a few weeks back and it has worked flawlessly. Have worn it around for hours at a time with very little discomfort. Very easy to pair with my samsung sch-u740 and also with my PS3.
Cons: Gets kind of staticy when you put object between the headset and your phone but nothing to send it back over. I have small ears and it fits fine but for someone with bigger ears it would be very uncomfortable.
