Ah yes. Did you see the Steve Guttenberg review comparing them to a muscle car:
I’m on the same page as him – these are great ROCK headphones. I reserve mine for genres that are already heavily processed in the studio and that have no ground truth (e.g., Rock, Electronic/EDM, and the little Hip-Hop I listen to), or for productions that could use more vibrato and bass (e.g., flat/dead/thin vocals). I personally hate them for ‘natural’ productions that explicitly avoided studio manipulation.
These are the only headphones where I bought a balanced cable and then took it off. First, it did nothing for the tone and details. Second, it came with a bulky XLR-4 connector and was awkward to use. Third, it took away the sensory experience of the braided factory cable. Muscle cars, 4x4s, Marshall Amps, and Rock & Roll. Take them as they are and for what they are.
Regarding price, I grabbed the factory Black Friday B-Stock offer of $550 and think that’s reasonable in the current market. [With a close initial inspection I saw no flaws at all to justify the B-Stock label.]
