Our Review
The Quick Verdict
The CMF Buds 2 is a budget TWS that brings 48dB hybrid ANC, 11mm custom PMI drivers with Dirac Opteo support, ChatGPT integration, and an exceptional 55-hour total battery life to the sub-₹2,700 segment. As part of Nothing's CMF sub-brand, the Buds 2 deliver minimalist design, genuine ANC performance, and unique AI features at a competitive price. The 55-hour battery is class-leading, the Dirac Opteo tuning provides balanced sound, and the ChatGPT integration adds a futuristic dimension. However, there's no LHDC codec, the gaming latency is high at 120ms, and the CMF brand is still establishing itself. For Nothing/CMF ecosystem users and tech enthusiasts who want AI on a budget, it's an excellent choice. For gamers, the high latency is a dealbreaker.
Bottom Line
The CMF Buds 2 is a well-designed, feature-rich budget TWS that excels in battery life, sound balance, and unique AI integration. The 55-hour battery is class-leading, the Dirac Opteo tuning is audiophile-friendly, and the ChatGPT feature is genuinely innovative. However, the 120ms gaming latency is a significant drawback for gamers, and the lack of LHDC limits audiophile appeal. For CMF ecosystem users and tech enthusiasts who prioritize battery and AI over gaming, it's an excellent choice. For gamers, the OnePlus Nord Buds 4 or Realme Buds Air 7 are better options.
Rating: 3.75/5
Pros
- + 55-Hour Total Battery Life — Class-leading, the longest in the budget segment.
- + 48dB Hybrid ANC — Effective noise cancellation with environmental adaptive technology.
- + Dirac Opteo Sound Tuning — Balanced, detailed sound with good separation and wide soundstage.
- + ChatGPT Integration — Unique AI feature for quick queries and assistance through the earbuds.
- + Clear Voice Technology 3.0 + Wind Noise Reduction 3.0 — Clear calls even in windy conditions.
- + IP55 Earbuds + IPX2 Case — Better protection than many competitors with case rating.
- + Minimalist CMF Design — Restrained, functional aesthetic stands out from flashy designs.
- + Fast Charging — 31 minutes for earbuds, 1.55 hours for case.
Cons
- − 120ms Gaming Latency — Too high for competitive mobile gaming; noticeable audio-visual lag.
- − No LHDC or Hi-Res Audio — Limited to AAC/SBC codecs.
- − High Latency Without Nothing OS — May be even higher on non-Nothing phones.
- − CMF Brand Still Establishing — Service network and long-term support less certain.
- − Bass May Be Too Neutral for Some — Dirac Opteo tuning prioritizes balance over punch.
- − No Wireless Charging — Case charges only via USB-C.
Verdict
The CMF Buds 2 is a well-designed, feature-rich budget TWS that excels in battery life, sound balance, and unique AI integration. The 55-hour battery is class-leading, the Dirac Opteo tuning is audiophile-friendly, and the ChatGPT feature is genuinely innovative. However, the 120ms gaming latency is a significant drawback for gamers, and the lack of LHDC limits audiophile appeal. For CMF ecosystem users and tech enthusiasts who prioritize battery and AI over gaming, it's an excellent choice. For gamers, the OnePlus Nord Buds 4 or Realme Buds Air 7 are better options.
