CMF Buds 2a — Dirac-Tuned. 42dB ANC. The Most Affordable CMF Earbud.

The CMF by Nothing Buds 2a is the entry point to CMF’s 2025 audio lineup — bringing Dirac Opteo sound tuning, 42dB hybrid ANC, and a 12.4mm bio-fiber driver to the most accessible price in the range. For first-time TWS buyers or anyone who needs a reliable, great-sounding daily driver without spending a lot, the Buds 2a delivers more than the price suggests.

🎵 12.4mm Bio-Fiber Driver — Larger Than Most at This Price

A 12.4mm bio-fiber composite driver — larger than the typical 10mm or 11mm driver at this price point — produces a warmer, fuller sound with deeper sub-bass extension. Bio-fiber diaphragms have a natural damping characteristic that reduces distortion while maintaining fast transient response. Co-tuned by Dirac (the Swedish audio DSP company whose technology is built into BMW, Volvo, and luxury home theatre systems), the Buds 2a’s sound is refined, controlled, and musical rather than harsh or fatiguing.

🔇 42dB Smart ANC — Reliable Everyday Cancellation

42dB Smart ANC is calibrated for the most common listening scenarios: office background hum, café ambient noise, commute rumble, and home appliance sounds. In indoor environments, it effectively muffles background noise; outdoors, it softens low-frequency traffic sound significantly. Three levels (Off, Adaptive, High) and a separate Transparency mode give you flexible environmental control without over-complicating things.

🎮 Low-Lag Gaming Mode + 6-Mic ENC

Activate Low-Lag Mode via the Nothing X app to drop audio latency for mobile gaming — keeping audio synced with on-screen action in PUBG Mobile, Free Fire, and casual games. Six ENC microphones ensure clear call quality even in moderate ambient noise. The Nothing X app adds further depth: custom EQ profiles, Ultra Bass toggle (for even more bass emphasis), Dual Device connectivity, and Find My Earbuds.
