What reviewers say

Both reviewers praised detailed sound and effective noise cancellation, but experienced occasional right-earbud dropouts. TechRadar found the housings bulky and missed volume controls; Tech Advisor found them light and comfortable, but criticised the case's charge-level indication and the need to clip the earbuds carefully into place. Their reports describe the firmware available during each review.
