These are the headphones that are currently being used in my studio. Back L-R: Beyer DT 880 600Ω; Beyer DT 990 Pro; Beyer DT 1990 Pro; AIAIAI Studio; Front L-R: Focal Clear Mg Pro; Sennhieser HD 660 s2; Grado 325e.
The Senn's are brand new. Took advantage of the $200 price drop. Beyer DT 1990's are great for mixing upper end detail. AIAIAI's are well isolated. Grados and DT 990's are for clients to use. Beyer DT 880's just work. If you can get a mix to sound good on them, you're almost home. 600 Ω version is different from other 880's.
I do the most critical work with the Focal Clear Mg Pros. The Mg drivers are angled and sound nearly like using studio monitors. I use Focal Shape 65 near fields with Mg tweeters which are perfect with the Clear Mg cans. I also have a pair of BW 705's and a REL sub for clients and for me to listen to vinyl.
There is no "good, better, best." They all do something specific that I like. The new Senn 660 s2's are voiced almost identically to the $1500 Focals. However, the Focals do imaging/instrument placement and create space like nothing else. Up/down/back/front/left/right/center--they are ridiculously good.
Love the new Senn's for leisurely listening. Sweet, much lighter than the Focals, lots of fun. $399 at the moment seems about right.
Edit: I have a large walk-in closet in my studio and this is the headphone area.
