Bose says changes in noise cancellation level are now smoother than before and that a new AI-powered noise suppression system improves call quality. Bose UK Support
What Hi-Fi? gave the earbuds 5 out of 5 for sound, features and comfort. It found the sound punchy and full-bodied, the noise cancelling among the best in class and calls clear, and wrote that the claim of smoother handling of sudden noise holds up. It counted Immersive Audio cutting battery to 4 hours and only three ear tip sizes as cons, and found the Technics EAH-AZ100 more detailed.
