Prompt Delivery, Case I find very good, equipment at the cost of real passable. At first it hurt the ear, now I know what it is sitting on top. Of course, it roars in the car and one hears not clear ... but the few bucks it really is sufficient to briefly lift with both hands on the control times. Duration talks would but exhausting time. Also in order to bridge with single-sided listening to music even for a short time, it is my opinion ok.
