Nice upgrade to the Sennheiser hd 600, 650, 6xx line up, better bass better imaging and better soundstage.

Got a lot of enjoyment out of these, especially since the hd 600 were already really good, these fix the lack of bass and upgrade the soundstage.

Definitely a more desisive audiophile headphone, but any issues with it are related to the msrp price (so at ~470 their good value) and EQ which can be easily fixed with good software.

Basically brand new condition, super well taken care of. Only selling to eventually upgrade to hd800
