"40mm drivers aren't usually found on compact, lightweight models like these (similar Koss models use 35mm drivers). This results in more bass and a larger soundstage. The detachable cable is also great for less wear (unplug them when you have to store them for travel). Lastly at this price range, this model is hard to beat." - TTL
