What reviewers say

Both find a comfortable fit, useful customisation and clear outgoing calls, but differ sharply on sound and value. SoundGuys praises bass and noise cancelling and recommends them; Tom's Guide finds weak bass, thin highs, inconsistent controls and inadequate cancellation beside busy roads. Both question the case controls, while SoundGuys also dislikes spatial audio.
