They do! I got mine around this time last year for 430 from audio46

Hey just FYI, the 770 are faaaaar from flat and neutral. I thought the same when I first demo’d them, but alas I was wrong. They are really well balanced, which can give off that impression, but they have boosted highs and bass with many peaks and dips through the frequency response.

For mixing I’d really recommend looking into the AKG 371. They’re not as fun but since you need a reference tool, these are much better for mixing.

Foam might cause too drastic of a change. Try paper towels or dried wet wipes if it doesn’t look terrible on the Anandas. That’s what I use on my 1990s and it addresses the treble (8khz and above) specifically and leaves the rest of the spectrum virtually untouched.
