It provides solid everyday comfort and good passive isolation, though its call quality and overall audio performance don't quite match some of its siblings.

- Pro:Comfortable stem design with good passive isolation
- Pro:Long total battery life (40 hours with case)
- Con:Call quality is below expectations despite four mics
- Con:Sound quality trails competitors like M5 and M7

- Pro:Long battery life with wireless charging case
- Con:Microphone quality is mediocre
- Con:Touch controls can be inconsistent
