Pick by room, not by brand. If a microphone is live in the same space, you need closed-back, which means the MDR7506 or the ATH-M50x. The MDR7506 is the cheaper reference and has been a studio fixture since 1991, but its cable is fixed, so a snagged cable is a soldering job rather than a swap. The M50x costs more and fixes exactly that, with a fuller, more liveable tuning that is slightly less neutral in the low end.
We changed the premium pick in August 2026. It used to be a bundled beyerdynamic DT 990 Pro listing that is now out of stock; the DT 900 Pro X replaces it and is a better recommendation on its own terms, because it drops to 48 ohms (so an interface output drives it) and adds the detachable cable the DT 990 Pro never had.
What we do not cover: the standard mixing reference above this price is the Sennheiser HD 650 or the Beyerdynamic DT 1990 Pro, and neither is in our catalog.
Basis: published specs, the long service record of all three models, and owner reviews. We have not listened to them. Ratings score each product on the merits with price left out, so the premium pick always sits highest. The tier tells you where a pick sits on price, not how good it is.
