Short answer: the Sennheiser HD 599. It ranks #71 of 134 over-ear headphones by sound quality, rated 3.6/5, at $239.95. The Cooler Master MH752 ranks #73, rated 3.5/5, at $189, $50.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Sennheiser HD 599 does well: A preference score of 73 and a modest 2.74 dB deviation from the Harman target in oratory1990’s measurement make this a fairly smooth open back. The catch: Sub-bass falls about 6 dB under target below 60 Hz, so the extra warmth sits higher up and the deepest rumble is missing.
The case for 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 catch: 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.
Buy the Sennheiser HD 599. It is rated higher for sound quality, and the $50.95 you would save on the Cooler Master MH752 does not close the gap.

The Two Headphones In Full
Sennheiser HD 599: $239.95 Amazon eBay
Pros: A preference score of 73 and a modest 2.74 dB deviation from the Harman target in oratory1990’s measurement make this a fairly smooth open back. Bass runs about 2 dB above target and the lows through the low mids are about 2.7 dB up, which gives vocals and guitars a full, warm body. At 50 ohms and 106 dB sensitivity it is easy to drive, and at 250 g it is light.
Cons: Sub-bass falls about 6 dB under target below 60 Hz, so the extra warmth sits higher up and the deepest rumble is missing. A 9.6 dB dip near 9.8 kHz and about 3.5 dB less air above 10 kHz take the sparkle off cymbals, while a 3.7 dB peak near 5.7 kHz can add some edge to vocals. The open back leaks sound and offers no isolation.

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.
