#88 AKG K240 Studio: $54.95 Amazon eBay
Pros: A preference score of 68 in oratory1990’s measurement puts it in the middle of the pack, with a fairly even tilt and bass within about 1.4 dB of target from 60 to 200 Hz. At 55 ohms and 104 dB sensitivity it runs fine from a phone or laptop without a dedicated amp. The semi-open design weighs 240 g and suits critical listening at home, and it is rated higher than the Sennheiser HD 280 Pro and the Sony WH-CH510.
Cons: Sub-bass from 20 to 60 Hz sits about 13.7 dB below target, so kick drums and synth bass lack rumble and weight. A 6.2 dB dip near 3.6 kHz pulls back vocal presence and detail, while a 3.7 dB peak near 7 kHz can add a touch of edge to cymbals. The semi-open back leaks sound and offers little isolation, and there is no microphone.
