Audiology patient test headphones (as opposed to the clinician monitor headphones) are awful for music, requiring 20+ dB of EQ at low frequencies, 10+ dB at high frequencies. They sound distant, overly sharp, weirdly not musical, seal poorly, and have uncomfortable headbands. The accuracy and correctness is in the audiometer, not the headphones. The headphones only redeeming feature is their similarity- they’re manufactured to a specification and distributed worldwide so a calibrated audiometer (should) yield the same effective results anywhere.
