CMF Buds 2a Wireless Earbuds
The CMF Buds 2a are true wireless in-ear headphones from the CMF by Nothing sub-brand. They use 12.4 mm bio-fibre dynamic drivers co-tuned with DIRAC and offer up to 42 dB hybrid active noise cancellation. Bluetooth 5.4 provides a stable connection with Google Fast Pair and Microsoft Quick Switch support. The set includes multiple ear-tip sizes for a secure fit.
Commuters and office workers needing decent ANC
These earbuds suit listeners who want effective noise reduction for travel or open-plan offices and appreciate a warm sound signature with strong bass. The IP54 rating handles sweat and light rain during exercise. Buyers who require multipoint Bluetooth for simultaneous laptop and phone connections should look elsewhere. Audiophiles seeking a neutral reference tuning or support for high-resolution codecs such as LDAC or aptX Adaptive will not find them here.
42 dB hybrid active noise cancellation
The headline specification is the 42 dB hybrid ANC system that targets low-frequency drone and mid-range chatter in daily scenarios. Combined with the 12.4 mm drivers and quad-microphone ENC array, it determines whether the buds meet your isolation and call-clarity needs. Battery life reaches 8 hours per charge or 35.5 hours with the case, and a 5-minute quick charge adds up to 2 hours of playback.
