Read the full review

If blocking out the world and sounding clear on calls are what you want most, these are excellent.

Love it

Meh

  • Superb noise canceling on engine drone
  • Much clearer calls
  • Fun, detailed sound
  • Touch controls can be switched off
  • Chunky fit
  • Up to six hours per charge
  • Case has no water rating

Where it shines

  1. Noise cancelling

    Quiet, Aware and Immersion modes let you set how much of the world gets in, with CustomTune fitting the sound to your ears.

  2. Calls

    Eight microphones and AI noise suppression clean up your voice on calls, whether you wear one bud or both.

  3. Travel

    Noise cancelling quiets trains and planes, and the case tops up on a wireless pad.
