What reviewers say
Reviewers agree the sound is smooth, detailed and open, and that the light headphones are comfortable. The common criticisms are strong competition at the price and a locking cable connection that limits cable choice; TechRadar and What Hi-Fi? found the bass short of punch, and What Hi-Fi? wanted thicker ear pads.
