Short answer: the AKG K240 MKII. It ranks #190 of 481 over-ear headphones by sound quality, rated 3.7/5, at $149. The Beyerdynamic DT 270 Pro ranks #212, rated 3.6/5, at $129.99, $19.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the AKG K240 MKII: In oratory1990’s measurement it earns a preference score of 75, with bass from 60 to 200 Hz within 1 dB of the Harman target, so bass guitar and male vocals sound full without boom. The catch: Sub-bass falls 6 dB below target by 63 Hz and sits more than 14 dB down at 30 Hz, so kick drums, synth bass and film rumble lose their weight.
The case for the Beyerdynamic DT 270 Pro: The median of 5 hobbyist measurements gives it a solid Harman preference score of 74 with a 2.17 dB spread, and its mids sit within about 1 dB of target, so vocals and instruments sound natural. Watch for: A 5 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
Buy the AKG K240 MKII. It is rated higher for sound quality, and the $19.01 you would save on the Beyerdynamic DT 270 Pro does not close the gap.
