Our Verdict

Sony MDR-7506

AKG K371

The AKG K371 are slightly better over-ear studio headphones than the Sony MDR-7506. The AKG have a much more accurate and well-balanced sound profile, leak less audio, and have a detachable cable. On the other hand, the Sony's frequency response is much more consistent among users.
