Short answer: the Cooler Master MH752. It ranks #123 of 216 over-ear headphones by sound quality, rated 3.5/5, at $189; the Fostex T40RP Mk3 ranks #160, rated 3.2/5, and costs $189.99, which makes this an easy call rather than a real tradeoff.
Why pick the Cooler Master MH752: The bass is balanced and slightly full, about 1.8 dB over target, with sub-bass only about 1 dB under, so low notes keep some impact. The tradeoff: Presence and lower treble are 3.9 dB and 3.1 dB below target, and a 9.2 dB dip near 9.3 kHz dulls cymbals and consonants.
Why pick the Fostex T40RP Mk3: This closed back planar magnetic model measures smoothly in oratory1990’s test, with only 2.57 dB of deviation around the target and sub-bass within 6 dB down to 20 Hz. The catch: Sensitivity of 91 dB/mW is low for an over-ear, so a dedicated headphone amp helps it reach full volume.

The Two Headphones In Full
Cooler Master MH752: $189.00 Amazon eBay
Pros: The bass is balanced and slightly full, about 1.8 dB over target, with sub-bass only about 1 dB under, so low notes keep some impact. Mids are close to target, within about half a dB through the vocal range. It is a closed 250 g design with a built in microphone and a 26 ohm impedance, so it works straight from a laptop or console.
Cons: Presence and lower treble are 3.9 dB and 3.1 dB below target, and a 9.2 dB dip near 9.3 kHz dulls cymbals and consonants. A 2.9 dB peak near 11.9 kHz and extra air above 10 kHz then bring back some fizz, so the top end sounds uneven rather than simply dark. Sensitivity of 97 dB means it needs a little more volume than the most efficient headphones.

Fostex T40RP Mk3: $189.99 B&H Photo Video eBay
Pros: This closed back planar magnetic model measures smoothly in oratory1990’s test, with only 2.57 dB of deviation around the target and sub-bass within 6 dB down to 20 Hz. Bass sits about 3 dB above target, giving a warm, solid low end for listeners who prefer a fuller sound. The closed design isolates from room noise and keeps sound in.
Cons: Sensitivity of 91 dB/mW is low for an over-ear, so a dedicated headphone amp helps it reach full volume. Upper mids and presence both run about 2.5 dB below target, which softens vocal detail, and a 4.5 dB dip near 11.9 kHz trims air. The Audio-Technica ATH-AD700X and Yamaha HPH-200 earn the same rating for less money. See headphone amps and DACs with enough power to drive it.
