Our Verdict
Bose QuietComfort Ultra Headphones Wireless
CMF Buds Pro 2
The Bose QuietComfort Ultra Headphones Wireless and the CMF Buds Pro 2 serve different purposes and different market price points. The Bose are premium over-ears, designed for people willing to pay top dollar for outstanding ANC. And to that end, they deliver. The Bose block out everything from the low rumble of plane engines to higher-pitched office chatter. On the other hand, the CMF are affordable in-ears that are extremely portable and still offer very good ANC. Their bass-heavy sound isn't as balanced as the Bose, but you can tweak the sound of both pairs in their companion apps.
