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
