The Sennheiser CX 80U and HD 400U promise high-quality audio on a budget.

TL;DR

Sennheiser has announced a significant upgrade for its affordable CX 80S earbuds and HD 400S headphones.
Renamed the CX 80U and HD 400U, both devices now sport USB-C connectors.
This provides future-proof, 24-bit/96 kHz digital audio playback.

Sennheiser has refreshed its popular CX 80S earbuds and HD 400S headphones with significantly upgraded successors. Renamed the CX 80U and HD 400 U, these feature USB-C connectors and support digital audio playback up to 24-bit/96 kHz. The update provides future-proof connectivity with modern smartphones, tablets, PCs, and gaming consoles. This comes at a time when the older 3.5mm standard is becoming less ubiquitous.

Both models are compatible with iOS, Android, ChromeOS, macOS, Windows, and SteamOS. Similarly, both devices feature a microphone for calls and sport an identical form factor to their predecessors. However, fashion-conscious buyers may be disappointed with the singular Black color variant. Likewise, both devices sacrifice advanced features, such as active noise cancellation, spatial audio, and integrated voice assistants, for a cheaper price tag.

The Sennheiser HD 400U feature a closed-back, over-ear design with passive noise isolation. The company claims that the cans deliver the same rich bass as the previous model, and they include a detachable cable and storage pouch. Conversely, the Sennheiser CX 80U are compact earbuds that come equipped with three ear tip sizes and a balanced sound quality. While both lack industry-leading features, the introduction of USB-C and their continually affordable price tag make them a compelling choice for price-conscious buyers.

The Sennheiser CX 80U and HD 400U are available now for $39.95 and $99.95, respectively. Both can be purchased from authorised dealers and Sennheiser’s website. They should remain relevant for the next few years.
