In my opinion I think these can be used as a DJ reference headphone. Why? Because of the smooth, rich sound these headphones provide. No, they won't ever be fully BASS headphones but the bass is so silky and punchy and you can drive these pretty hard in the SBX Pro Studio software. That being said your ears won't get tired as with other headphones with too much bass. Here the bass is defined. With the right settings these would be pretty good DJ headphones and you won't get tired because they are so light, allowing you to focus on your DJ set.
