I already own the Audio-Technica AD900x and The beyer Dynamics Custom One Pro.
I use the first one for clear and vivid highs and for a large and precise soundstage (mainly for electronica, idm, classical etc.). I truly love it. To me, the second one is good for urban or pop music beats (thanks to the bass reflex system), but got the disadvantage to make me quite claustrophobic...
I'm thinking about buying a third pair but I'm lost...
Considering you got the AD900x and the COP, what would be your next move ?
I want something that sounds really different and at least as good as my AD900x. I'm thinking Grado but is it a good move ?
Thank you in advance for your precious advice.
