Bought to replace an identical pair from another manufacturer that had withstood three years of fairly rough use. The sound quality is good, the "vibration" which sounds like a gimmick gives the base a nice extra punch, so the sound quality seems better. The microphone is good but not adjustable. The only major complaint is that the built-in volume wheel is placed so low that it sometimes rubs against my leg and changes the volume. (although this one seems better than my previous one with a tighter dial) Bought as a gift and for a friend of mine. Good value for money.
