What Buyers Say
Bose QuietComfort (888507-0100)
The Bose QuietComfort earbuds receive mixed feedback. Many users praise the excellent sound quality, comfort, and effective noise cancellation, especially for music and general use. However, a significant number of complaints focus on fit issues (earbuds falling out or being too large), connectivity problems (random cutouts, disconnections), and a flimsy charging case. Some users also report inconsistent noise cancellation in noisy environments and issues with the left earbud. Overall, while many are satisfied, the product's reliability and fit are common concerns.
Pros
- Excellent sound quality
- Effective noise cancellation
- Comfortable fit
- Great bass
- Good app features
Cons
- Fit issues (falling out)
- Connectivity problems
- Flimsy charging case
- Inconsistent noise cancellation
- Left earbud issues
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
