Nothing Headphone Pro B175
88 out of 100 low confidence 9 reviews
The CMF by Nothing headphones are widely praised for their exceptional value at around $80, offering premium build quality, comfortable fit, and impressive sound with deep bass and clear mids/highs. Active noise cancellation is effective for the price, though not top-tier, and battery life is excellent. Minor drawbacks include a soft carrying pouch instead of a hard case, a slightly bulky design, and a volume scroll wheel that adjusts in 6% increments. Overall, users strongly recommend them as a budget-friendly alternative to high-end models like Sony XM4/XM5.
