Our verdict

Adaptive noise cancelling and a long total playtime suit commuters and desk workers. The listing gives no water resistance rating or Bluetooth version, so check those before buying for the gym.

Overview

Blocking a wider range of distracting sound, these earbuds detect noise around you and select a suitable cancelling level on their own. A charging case supplies the extra playtime between outlets.

Automatic noise cancelling that follows your surroundings means little fiddling on trains, planes and in offices. The case extends listening well past one charge. The gaps are in the listing, which skips water resistance and the Bluetooth version.

Who it's for

Travelers and open-plan workers get the most from the adaptive cancelling and the long case-backed playtime. Buyers who need a confirmed waterproof rating, or a specific Bluetooth version, will find neither in the listing.

Pros and cons

Pros
  • Adaptive noise cancelling tailors itself to surroundings
  • Long total playtime with charging case
  • Fast charging gives hours from a short top-up
  • LDAC mode for Hi-Res wireless audio
Cons
  • Water resistance rating not listed
  • Noise reduction is an up to figure
  • Single charge covers only part of total playtime

Performance notes

Noise cancelling adjusts by detecting outside sound and choosing a level for indoor, outdoor and travel settings. Sound comes from double-layer diaphragm drivers aimed at strong bass, clear mids and bright treble. Choosing LDAC mode is how the earbuds deliver Hi-Res wireless audio, and the case recharges them between uses.
