My friend loves technology and has a pretty decent setup in his basement for movies. He bought his dad some of the higher quality beats headphones and is convinced they're the best. He listens to a variety of music but his favorite bands are Blink 182 and Angels and Airwaves but also really likes hip hop. He would be playing the headphones from his computer/ipod unless newer headphones will convince him to upgrade his source or buying an amp. Price range would be less than the beats headphones. Any suggestions?
