These have a seam that holds it shape better. Which is fine. He says he likes it. I was a little worried about the design of this headset, but the moment I put it on, everything was fine. I do recommend using a fitness tracker rather than relying on the calorie tracker on the machine. My daughter has narrow feet and these were simply too wide. I was on the fence whether these hooks would hold. I?ve tried charging again, but nothing works. I read all the reviews and comments from seller so I sized up one size as recommended. The Zone Wireless dongle sticks out a tiny bit more than the regular Logitech unifying receiver.
