What Buyers Say
CMF BY NOTHING Buds Pro 2 B172
The CMF Buds 2 Pro are widely praised for their exceptional sound quality and value for money, with many users comparing them favorably to more expensive competitors. The dual-driver design delivers clear highs and deep bass, while the Nothing app offers extensive customization. However, a few users report durability issues, with one noting the buds became unusable after five months. Build quality is described as decent but not premium, though this helps keep the weight low.
Pros
- Exceptional sound quality for the price
- Dual-driver design for clear highs and deep bass
- Extensive customization via Nothing app
- Comfortable fit with soft ear tips
- Good noise canceling and transparency mode
Cons
- Build quality feels slightly cheap (plastic)
- Durability concerns (unusable after 5 months reported)
- Case dial can trigger accidentally in pocket
- Firmware update required out of the box
- No 10-band EQ in app
Technics EAH-AZ80
The Technics EAH-AZ10 earbuds receive overwhelmingly positive feedback for their exceptional sound quality, featuring clear separation, wide soundstage, and natural tuning that rivals higher-end models. Users praise the comfortable and secure fit, effective noise cancellation that doesn't muddy the audio, and impressive battery life lasting up to 7 hours. However, a few critical reviews highlight poor touch controls that are unresponsive, and one user experienced a significant volume imbalance after 1.5 years, with the company offering only a 10% discount on a replacement rather than a fix. Overall, these are highly recommended for audiophiles and daily use, but potential buyers should be aware of possible durability and control issues.
Pros
- Exceptional sound quality with clear separation
- Comfortable and secure fit
- Effective noise cancellation without audio degradation
- Impressive battery life up to 7 hours
- Great call quality
Cons
- Unresponsive touch controls
- Volume imbalance after extended use
- Poor customer service for defects
- Bulky design for some users
- ANC not sufficient in very loud environments
