Sennheiser has announced two new audio products, the CX 80U earbuds and the HD 400U headphones. These new models are updated versions of the popular CX 80S and HD 400S, with one big improvement that many users will like. Both now use a USB Type C connection, making them ready for modern phones, tablets, PCs, and gaming devices.
The new USB C connection allows sound to go straight from the device to your ears without delay. This helps keep audio clear and in sync, which is useful for music, videos, calls, and games. Both the CX 80U and HD 400U support high quality digital audio up to 24 bit and 96 kHz, so users can enjoy clean and detailed sound on many platforms.
According to Christian Ern, Senior Product Manager at Sennheiser, these products are made for people who want simple use without losing sound quality. You just plug them in and start listening. An in line remote and microphone are also included, making them useful for daily calls, online classes, and work meetings.

The HD 400U headphones keep the same strong sound style that made the older HD 400S popular. They offer deep bass and a closed back design that helps block outside noise. This makes them a good choice for home, office, or study use. The headphones are light, easy to carry, and come with a storage pouch and a detachable cable for neat travel.
The CX 80U earbuds are made for users who prefer something small and easy to wear. They deliver balanced sound with a bit of punch and help reduce outside noise. Three different ear tip sizes are included, so users can find a comfortable fit for long listening sessions, whether they are studying, gaming, or relaxing with music.
Both models work with many systems, including iOS, Android, Windows, macOS, ChromeOS, and SteamOS. They use a MEMS microphone that captures voices clearly while keeping background noise low.
