I know you would not regret purchasing these but I have to say that at first they are tight. Fast easy and in good condition. Der Magene T100 ist genauso leise wie der teure Trainer und viel leiser als Wheel on Trainer. It was the reason why i bought this for him and hes so excited walking around the house with it. spent over 20 hours of my life to make it works with my brand new computer, the headset had the connection problem and the control issue. Really good for healthy walking. I have $500 worth of products I cant return for refund. 5?3? 130lbs, got a size S. The only reason it got two stars was because amazon was kind enough to not make me it apart to ship it back and I partially blame my own naivety for purchasing such a cheap thing. Yes, it is a plus under comfort as it keeps the headphones light.
