#124 AKG K271 MKII: $214.38 Amazon eBay
Pros: A closed-back studio design with 104 dB sensitivity at 55 ohms, so it plays loudly from a phone or laptop without an amp. Treble from 6 to 10 kHz and the lower mids land almost exactly on the Harman target in oratory1990’s measurement. A slightly bright tilt suits listeners who prefer a neutral to bright sound.
Cons: Bass is thin, with sub-bass about 15 dB and the 60 to 200 Hz region about 8 dB under target, so music lacks weight and punch. Presence from 3 to 6 kHz is down about 6 dB, with a 7.5 dB dip near 4 kHz that pulls vocals and guitars back. At 240 g with a preference score of 48, the Beats Studio3 Wireless is rated higher.
