I've been listening to them for less than a week and they are amazing! I own the HD800S and of course it's better than MD+ in sound quality but for a $300 earphones to be comparable with $1600 headphones is a nice feat! personally I LIKE THEM! I'll keep both. These are worthy of the price, just wished if they provided a better cable (It's not that bad) & I ordered a good one from null-audio already.
