What reviewers say

Both praise fuller, better-controlled sound, improved noise cancelling, comfortable fit and convincing film immersion, but favour rivals for musical detail and criticise the non-folding design. TechRadar finds the sound close to leading rivals and calls clear; What Hi-Fi hears weaker rhythm and dynamics and more background noise during calls.
