#64 AKG K712: $469.99 Amazon eBay
Pros: The open back gives a wide, airy presentation with a flat midrange, presence and treble within about 0.3 dB of the target between 3 and 10 kHz. Bass from 60 to 200 Hz is about 1.4 dB warm, which adds a little body. At 235 g it is light, and 105 dB/mW sensitivity is high for a 62 ohm design.
Cons: Sub-bass is about 3.7 dB under target and the low mids are about 3 dB hot, so music sounds a touch thick in the midrange while the deepest bass lacks rumble. A 6 dB dip near 9.4 kHz and a 3.8 dB peak near 5.9 kHz make treble slightly uneven. The open design leaks sound and offers no isolation, and the Austrian Audio Hi-X65 matches its rating for a lower price.
