## What reviewers say

**Bose QuietComfort Ultra Earbuds (2nd Gen)** — Two whitelisted outlets (SoundGuys, What Hi-Fi) both hands-on tested these and rate them a strong premium pick at an unchanged $299 / £299: class-leading noise cancelling and a comfortable, secure fit via Bose's stability bands. SoundGuys measured 85% external-noise reduction and a below-average 5h34m battery, and knocks the poor 3-band EQ. Verdicts split on sound: What Hi-Fi awards five stars for richer, punchier tuning, while SoundGuys' reviewer personally dislikes the bass/treble-heavy signature and calls the refresh minor enough to just buy the cheaper 1st-gen on sale.
