#9 Beyerdynamic MMX 300: $325.00 Amazon eBay
Pros: It scores 91 on the Harman model, with bass from 60 to 200 Hz and the whole midrange within about half a dB of target. A built-in microphone and closed back make it practical for calls, gaming and noisy rooms, and 32 ohms with 96 dB SPL sensitivity runs from a phone or laptop. Its tuning is slightly warm.
Cons: The top end is uneven, with a 4.3 dB dip near 9.5 kHz followed by a 6.1 dB peak near 11.9 kHz and air above 10 kHz about 5.3 dB hot. That can make cymbals and strings sound sharp or glassy. Sub-bass is about 3.2 dB under target, so the deepest bass notes lack some rumble.
