thats a weird one... i can speculate though.
the mobius has builtin 3d and head tracking, the dt1770 is a stereo headphone. yw
did you make a face like this? -.-
;] so the dt1770 is not quite as lively and undamped as some of the lower model beyers, but its still got that bass bump, elevated treble, and low distortion
The Mobius can mimick that signature if you want it to, it can play flat as a board, v shaped, w.e you want really which makes it tough to compare. For me with a pad change and some additional eq they sound really excellent, and I use 3d all the time with room ambience at about 30. They're intensely detailed, balanced and responsive. You can boost the bass up 5db+ if you want with little distortion, and theyve already got quite a bit of treble as I bring that area down about 5db. The built in virtualization, head tracking, and bluetooth 5.0 ldac with planar transducers sets them apart from everything else on the market. I quite literally almost never use my other headphones when I'm not using m desktop systems, unless I need in ears for yard work or something like that.
So ya vs the dt1770s? Mobius wins =p
