Most Mojo owners seem to think it does. Personally, I'm skeptical. The HD600 sounds best on a desktop amp. Then again, I don't have a Mojo, so I can't claim fault here. One thing does seem clear from all the reviews and impressions: If it doesn't drive the Sennheiser to its absolute potential, it must surely come damn close. It will sound superb, and you will not despair.
