What Buyers Say
CMF by Nothing Buds 2 Plus
The CMF Buds 2 Plus deliver exceptional audio quality and value, especially for their sub-$100 price point. Users praise the superb sound, effective ANC, spatial audio, and comfortable fit, though some note limited touch controls and mediocre noise cancellation in noisy environments. The Nothing app enhances the experience with customization, but classical music performance and bass-heavy default EQ may not suit everyone.
Pros
- Superb sound quality
- Excellent value for money
- Effective active noise cancellation
- Spatial audio feature
- Comfortable and secure fit
Cons
- Limited touch controls on left bud only
- Mediocre noise cancellation in loud environments
- No track backward skip
- No volume down control
- Poor battery charge indicator on case
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
