What reviewers say

Reviewers agree the comfortable fit, folding design and effective noise cancellation suit travelling. What Hi-Fi and TechRadar find competing Sony models more expressive and detailed, while SoundGuys praises the broadly balanced tuning. SoundGuys also finds the microphone admits background noise; newer competitors offer more features and longer battery life.
