It has built-in touch sensors in the ear pieces but it is a little bit of a learning curve. Though of course this would probably void the warranty. Low quality broke within first 2 weeks Sound is amazing. You can tell how wide it is from the pic I uploaded shows a can of mud mask exactly fits in it. It make my kitchen look Junkie. It fit so perfect. Looks so much more expensive than it was. It seems identical and sounds just as good if not better. They lasted at least 6 months which about what I would expect from a cheap pair but not less than a month of light wear.
