Our Verdict
Sennheiser HD 650
AKG Q701
The AKG Q701 are better critical listening headphones than the Sennheiser HD 650. The Sennheiser have a disappointing soundstage for open-backs, and their treble range depends on the positioning of the headphones and ear shape. The AKG also has an extra 20-foot cable. The Sennheiser are more expensive, making the AKG a better pick.
