Sennheiser CX True Wireless
The Sennheiser CX True Wireless earbuds receive high praise for their exceptional sound quality, which many reviewers describe as the best they have ever heard from wireless earbuds, with clear separation of instruments and balanced bass and treble. Setup is generally easy, though some users note the quick-start guide is lacking and firmware updates can take up to 40 minutes. Comfort is good for most, but a few users experience fatigue with prolonged wear, and one verified reviewer reported a defect after six months where one earbud stopped working properly. Overall, these earbuds are recommended for audiophiles on a budget, especially if you are willing to use the equalizer app to fine-tune the sound.
Pros
- Exceptional sound quality with clear instrument separation
- Balanced bass and treble
- Easy setup and pairing
- Intuitive touch controls
- Good passive noise isolation
Cons
- One earbud failed after six months
- Firmware update takes up to 40 minutes
- Quick-start guide lacks information
