I only use them for phone calls and video conference calls. app = mega ! Even though I live in US I am able to receive call for the second sim from my country. They are a little big, but they still are a great fit. I tried out both the S3 Frontier and the Galaxy watch and came to the following conclusions. Wish there was a magnet or clip to hold them in it cause once you open it they will fall out if you dont close it. First, the remote extenders seem unbelievably chintzy and cheap for $49. 5 would be reasonable IMHO. Very less bass Terribly difficult to get on, even with my help.
