His is 6ft and 190 lbs. They have a built in mic, a sensor to pause music when the right one is removed from your ear and a rechargable case. I am still working on trying to adjust the settings but not sure if that will help I was sitting most of the time and still the straps cut into my ankles and scraped them upend bruised them. Note, I have no affiliation with this app. So if you are in a loud room you may have trouble listening to tv shows on your phone or music. The price was reasonable, my husband said it installed easily and its very quiet. I really like this charging station, it?s everything I need for my charging needs. We used it for a bike rack, but the rack sways and rattles back and forth while you are driving. I tried different devices to make sure it wasnt just my device.
