I produced beats for a while with thee and dj'ed with them as well. The bass is good for listening to music, but for producing electronic music like I do your gonna need an EQ and pump up the bass a bit. I always just had to take my laptop to my car and test my bass lines on my subs to make sure it sounded right. Also after about an hour and a half they start to get uncomfortable on the ear, which kinda sucks if you plan on using them for DJ purposes. Durability is alright. they lasted me a year before they blew even tho i broke them in properly (on full blast 2-8 hours a day). Over all pretty good buy for the money. They are crisp, accurate, and clean. able to Pick up the really low lows if you have them eq'ed right. I enjoyed the cord length, you can be hooked up to your computer/mixer or whatever and walk across the room and grab your drink without having to take them off. Also they have decent noise cancellation which is a plus.
