In one word - Superb
Bought these in a package together with Sennheiser DAC HDV820 and all I can say is WOW!!!The difference between the reproduction on these and say my Sony MDR-1000X is like chalk and cheeseEvery familiar track is like a whole new experience- the openness and clarity is awesomeSome say they are a little lacking in bass but not for me.I have only played a dozen or so tracks from my pop collection so I will be interested to here how well they reproduce my jazz, blues, classical and opera collections.Money well spent especially if you travel a lot as I do and cannot always have my home hi FI set up to listen to
