CMF by Nothing Buds 2a Specs Summary
Review Verdict: The CMF by Nothing Buds is a highly aggressive and stylish budget offering that stands out with its minimalist design and premium matte-finished square case. Sporting 42dB Active Noise Cancellation, reviewers note it impressively mutes low-frequency AC hums and traffic rumbles, outperforming many competitors in the sub-₹2,500 segment. The 12.4mm Dirac-tuned drivers deliver a heavy, bass-forward sound profile (enhanced by Ultra Bass Technology 2.0) that EDM and Bollywood music lovers will appreciate, though audiophiles might find it a bit treble-shy. With excellent 35.5-hour battery life, Dual Device Connectivity, and a fully-featured Nothing X companion app, it's one of the best overall value-for-money ANC earbuds available right now.
