Our take

The K712 keeps AKG’s spacious, analytical character but adds the low-end body the 701/702 famously lack. It’s the easiest of the family to just enjoy, still wants power, and stays honest through the mids. The one to get if lean bass put you off the 701.

Measured by Jamey Warren on a Head Acoustics HMS II.3 artificial head — raw response, left/right averaged, normalized to 0 dB at 1 kHz. From the Sonic Temple Archive(2008–2014, one unit per model). Honest limits: seating variance runs ±0.4 dB in the mids to ±3.9 dB above 12 kHz, and open headphones read bass-light on this fixture — don’t read fine treble detail as settled. How we measure →
