I use the headset while working out in the gym. It's clearly more fun if you are not dependent on its cable clutter and the device connected. For me it was especially handy when I wore sportswear without pockets. What had me somewhat disturbed was the fact that when something between headset and mobile phone, there was little dropouts came. If it were free path to the headphones, there is no problem even with 8m. The plastic for fixing the ear, I think it's great, there is a playing sports make a safe feeling and you are not afraid to lose it. The battery life is in my opinion sufficient and also the coupling is quick and easy and you always get through a light feedback. All in all, for me to make a good product for sports.
