They are strong, sturdy and well made. Well done Huawei, keep up the good work. on flat pavement. Ive paid hundreds of dollars for other shoes, and they didnt stand up to the pounding like this one. I found these and thought I would give them a try. Well, was I WRONG! My car was packed, so I had to haul my bike up on a rack, which I had never done before. I totally recommend these if youre getting a new headset or your first wireless headset, but as a laterally upgrade it probably wouldnt be worth it unless youre a stickler for great audio quality like I am. Try it, but don’t tell anyone how great it is. My opinion is still out on this.
