Bass is simply phenomenal! punchy and lethal, feels like a planar but without the planar disadvantages (oversize and heavy weight), I’m really not sure how did beyerdynamic manage to get this kind of massive powerful bass from such small dynamic drivers, moreover; while very bassy and warm sounding; no detail is lost when bass is punching through your skull, it really is a master of keeping its very high resolution and preserving detail whether its treble or mids, all is there and all perfectly intact, if you are a bass head that happen to love high res audio too look no farther.
another aspect i love is its warm sounding profile which is a welcome thing that is rarely found in ultra-high end headphones, very smooth and comfy sounding, those headphones was intentionally tuned for home use and entertainment, it should never cause you any fatigue no matter how long or loud you listen to them which is a plus in my opinion, some might be turned off because of its very warm sound nature and its totally understood if you are used to more bright sounding headphones, but unless you're planning to use the headphone strictly for audio production/monitoring i highly advise you to give it a few days till your ears get used to its warmness and trust me it will grow into you and you will love it for any and all entertainment purposes be it music, cinema or gaming, damn if that shotgun doesn’t sound epic!!!
Finally sound stage and imaging is simply great and is what you would come to expect from any open back headphone, not much to say here, all is good.
now the only disadvantage i see is its fit and comfort, its not exactly uncomfortable; but its not the best either, the ear cups are a bit on the smaller side, barely fit my ears (which are not exactly the biggest ears btw), also the fit is a bit on the lose side so be careful they don’t fall down if you happen to move fast or lean down to grab something ... so yeah i hope T1 4th gen will address that.
