#40 Sony MDR-7506: $129.99 Amazon eBay
Pros: A preference score of 83 with a deviation of only 1.7 dB from the Harman target in oratory1990’s measurement is excellent for a closed studio headphone. Bass and low mids sit within about 1 dB of target, so vocals and instruments sound natural and uncolored. At 260 g with a 106 dB/mW sensitivity, it plays loud straight from a phone or laptop without an amp.
Cons: Presence and treble run about 3.5 dB hot, with a peak of 6 dB near 4.5 kHz, which makes vocals forward and cymbals or sibilance sharp at higher volumes. Air above 10 kHz is about 2.6 dB low, and the wired-only design has no microphone.
