What reviewers say

Both find comfortable cushioning, effective noise cancelling and long battery life. Their listening impressions differ, with Tom's Guide enjoying the lively, spacious sound and SoundGuys hearing uneven treble and recommending EQ. SoundGuys praises the microphones' rejection of background noise, while Tom's Guide finds outdoor wind interferes with calls. SoundGuys also criticises the app experience.
