#75 AKG K240 MKII: $149.00 B&H Photo Video eBay
Pros: 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. A gentle 2.8 dB lift in the low mids gives voices and acoustic instruments a warm body, and the treble from 6 to 16 kHz stays within about 1 dB of target. At 240 g with a semi-open back, it suits warm and neutral listeners who want an airy presentation.
Cons: 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. A 4.2 dB dip near 4.4 kHz followed by a 4.3 dB peak near 7 kHz makes the upper treble a little uneven, and the semi-open back leaks sound and blocks little outside noise. The Thinksound ov21 is rated higher and costs less.
