CMF BY NOTHING Buds Pro B172
These CMF Buds deliver impressive sound quality with dual drivers and LDAC support, often compared favorably to much pricier competitors. Users praise the comfortable fit, long battery life, and useful case controls, though noise cancellation is noted as merely decent and the build feels a bit plasticky. A few minor complaints include the lack of a USB-C cable and a 5% battery display granularity, but overall they are seen as excellent value for under $60.

- Long battery life
- Useful case controls
Cons
- No USB-C cable included
- Battery display only in 5% increments
