What is the difference between the Sennheiser CX 80U and CX 80S?

The CX 80U replaces the CX 80S with a USB-C connector and adds a built-in DAC supporting 24-bit/96kHz hi-res audio. The driver, design, and sound character are essentially the same. The CX 80U works directly with modern USB-C devices without a separate dongle or adapter. The CX 80S used a 3.5mm connector and required an external DAC or adapter for USB-C devices.

Does the CX 80U work with iPhones?

Yes. The CX 80U is class-compliant and plug-and-play with iOS and iPadOS devices via USB-C. It connects directly to iPhone 15 and later, iPad models with USB-C, and other Apple devices without requiring any app, driver, or additional adapter.

Is there a companion app or EQ for the CX 80U?

No. The CX 80U does not have a companion app or on-device EQ. The sound signature is fixed at the factory tuning, which is balanced with controlled bass and clean midrange.

Does the CX 80U work for gaming?

Yes. The USB-C connection provides a direct, low-latency lossless audio path suited to gaming on phones, tablets, handheld consoles including SteamDeck, and PCs. The MEMS microphone supports in-game voice communication.

Sennheiser CX 80U USB-C Wired Earbuds

The Sennheiser CX 80U is the USB-C successor to the popular CX 80S, updated for modern devices that no longer include a 3.5mm headphone jack. The core design and 9.7mm driver are carried over from the CX 80S, with one significant addition: a built-in digital-to-analog converter (DAC) integrated directly into the USB-C connector. This means no dongle, no adapter, and no additional cost to get lossless, hi-res audio from any USB-C device.

The built-in DAC supports 24-bit/96kHz digital audio playback, covering virtually all lossless and hi-res streaming content available on Apple Music, Tidal, Amazon Music HD, and similar services. The CX 80U is class-compliant and plug-and-play across iOS, iPadOS, Android, ChromeOS, macOS, Windows, and SteamOS devices. It connects and plays without any app, driver, or pairing process.

Sound signature is balanced with controlled low-end presence, clear midrange, and refined treble. Passive noise isolation from the in-ear fit handles ambient noise without ANC circuitry or battery requirements. The in-line one-button remote with integrated MEMS microphone supports music playback control and voice calls.

All in-stock orders placed before 5pm EST Monday through Friday ship the same day. Free ground shipping on all orders over $9.99 within the 48 contiguous United States.
