What Buyers Say
Sennheiser CX Plus
The Sennheiser CX Plus earbuds deliver excellent sound quality with crisp highs, deep bass, and good instrument separation, which many users consider premium. However, the ANC is underwhelming compared to competitors in the same price range, and the companion app has room for improvement. Battery life is solid at around 8 hours, and the earbuds are comfortable once the right ear tips are chosen. A few users reported connectivity quirks and one experienced a hardware failure after five months.
Pros
- Excellent sound quality
- Good battery life (8 hours)
- Comfortable fit
- Good transparency mode
- Useful touch controls
Cons
- Underwhelming ANC
- App needs improvement
- Bulky case
- Volume control confusion
- Occasional connectivity issues
Technics EAH-AZ100
Users are overwhelmingly positive about the Technics EAH-AZ100 earbuds, praising the exceptional sound quality, especially with LDAC and Dolby Atmos, and the surprisingly effective AI-powered call noise cancellation that blocks out background noise like screaming kids or car washes. Comfort, customization via the app, and solid battery life are also highlighted. The only potential downside mentioned is the high price, but most feel the premium features justify the cost.
Pros
- Exceptional sound quality with LDAC
- AI-powered call noise cancellation
- Comfortable fit for long wear
- Customizable EQ via app
- Solid battery life
Cons
- High price point
- ANC slightly weaker than AZ80
