This set really is a nice thing to have to supplement any bodyweight workouts. It has more than enough volume to hear myself clearly over a full live rock band, and enough headroom to eliminate distortion. In the Chaco, I go 1/2 size smaller. I have to be able to get up and walk around. It also pinched on the skin multiple times causing minor bleeds. Fits perfect got size 4 n I?m 6 n women I dont know why but after one week of use, it stopped working and and the same problem as my other one. Straps are too wide to fit comfortably. I like this product very much and as long as you go into a beam or use really strong molleys you should have no problem. The quality of the sound and the rendition of the battery was awful.
