Sennheiser CX 80

Headphonecheck described the CX 80S as a very affordable in-ear headphone that still manages a strong sound image. The review pointed to its small dynamic drivers, low-end extension, and light build as strengths, with the overall impression being solid value rather than premium refinement.

Macworld’s review said the CX 80U is a simple but good-value USB-C wired earbud, with solid audio for the price and broad device compatibility. It emphasized that the earphones skip extras like Bluetooth and noise cancellation, but still work well thanks to their fit, inline controls, and microphone.

TechRadar concluded that the CX 80U delivers unusually strong sound quality for a budget wired USB-C earbud, with clean bass, clear mids, and crisp treble. It also praised the build and isolation, while noting drawbacks like the lack of volume buttons and only average microphone performance.

Tom’s Guide found the CX 80U to be an affordable wired option with decent sound and a straightforward feature set. Its review highlighted the USB-C connection, 9.7 mm drivers, and compact design, while implying that the earbuds are best suited to basic everyday listening rather than feature-rich use.
