my monster beats tour headphones were a gift from a friend and I've had this amazing piece for quite sometime now, but it suddenly died on me, and i can't afford to buy another one. So I would like to ask, what cheaper headphones out there are on the same par (or almost on the same par) as these Monster Beats Tour headphones? are there any Sennheiser or AKG in-ear phones out there that can match the Monster? thanks...
