Quite a lot, actually. It doesn’t have the soundstage and openness of an open back, but it is pretty wide for a closed back. Had to EQ the mids a bit to clean them up and bring them forward a bit more, but the bass and treble are solid and clean. For $149, I think they were a steal.

I got the Sundara closed back a couple of weeks ago for $149; does that count?

I bought a set at that price; just waiting to unbox and set up. If they sound half as good as my 4xx’s, I will take that as a win. Hell, even my R7-DX’s sound pretty good comparatively, so I am not worried. EQ exists to balance out rough spots.
