DT 900 PRO X : Really good except a teeny tiny design flaw

As an average audiothusiast, the sound output is superb with the low volume setting giving normal output sound even for being open cans. As such, it can be comfortably repurposed as a subwoofer for the times you just don't want to wear them.

Smooth sounding. Not terribly bass-y which I like. Cushion ear padding and being detachable makes it great for cleaning and long use which I find true.

I would not necessarily recommend it for long hair or for only if you have your hair neatly tied because the design where the cans meet the handband has a button-like clip (gap and all) that easily catch any stray hairs. Small enough it just manage 1-2 strands but once caught it will take some careful prying to get it loose. Which either damage or lose the hair. That said if you are able to adjust to this small design flaw it's a good value headphones.
