Wired earphones USB-C Sennheiser CX 80U black

Sennheiser CX 80U are wired earphones with a digital USB-C connector, designed for playing music, podcasts and films and making calls from devices fitted with a compatible USB-C port. The model combines closed-type dynamic drivers with a built-in microphone and an inline remote on the cable. Wireless connectivity and battery charging are not needed, so the earphones are ready to use as soon as they are connected to a device.

Wired USB-C connection The earphones use a USB-C connector that transmits audio directly from a compatible smartphone, tablet, laptop, computer or other device with a USB-C audio output. The wired connection requires no Bluetooth pairing or additional app installation. The solution is particularly useful with modern devices that lack a conventional headphone jack 3,5 mm.

Digital audio without compression CX 80U use digital audio transmission via USB-C. This connection method avoids the compression typical of Bluetooth transmission and provides a direct signal path from the source to the earphones. The model supports audio playback at up to 24-bit resolution and a sampling rate of 96 kHz, so it can work with high-quality audio material, provided the connected device and app also support it.

Natural and balanced sound The dynamic drivers in a closed design are intended for everyday listening to music and other audio content. The frequency response from 17 Hz to 20 000 Hz covers the range used when playing music recordings, films, audiobooks and podcasts. An impedance of 28 Ω and a sound pressure level of 119 dB SPL at 1 kHz and 1 V RMS define the operating parameters of the drivers.

In-ear design and passive isolation The in-ear form allows the drivers to sit closer to the ear canal, and the closed construction limits the leakage of some ambient sound. CX 80U use passive noise reduction, without active ANC. Correct fitting of the eartips helps achieve a more stable fit and more comfortable conditions when listening at home, while travelling or at work.

Eartips in three sizes The package contents include silicone eartips in sizes S, M and L. Choosing the right size makes it easier to fit the earphones to the individual shape of the ear. A proper fit can improve comfort and reduce ambient sound entering the ear. The set lets you start using the earphones without buying basic eartips separately.

Microphone and inline remote The built-in omnidirectional MEMS microphone enables voice calls via the connected device. The inline remote on the cable allows you to operate selected functions without reaching for a smartphone or computer, including controlling playback and answering and ending calls. The microphone's pickup range is from 100 Hz to 10 000 Hz, and its characteristics suit phone calls and voice communication.

Convenient use without a battery The earphones are powered directly from the connected device, so they do not need charging and have no specified battery life. The wired design means they can be used immediately after connecting, without waiting for a wireless link to start. This is a practical solution for regular music listening, remote work, study and calls made from USB-C devices.

Cable length 1,2 m The 1,2 m cable provides freedom of use with a smartphone, tablet or laptop. The USB-C connector is at its end, and the module with the microphone and remote is placed on the cable, making it easy to operate while wearing the earphones. The one-piece wired construction does not require a separate charging case or any additional power components.

Use with USB-C devices Sennheiser CX 80U are designed for devices that support audio via USB-C. They may work with smartphones, tablets, laptops, computers and other compatible devices fitted with this standard. Before use, make sure the USB-C port on the specific device supports audio output, as the presence of this connector alone does not necessarily mean it supports USB-C earphones.

Black, compact design The black colour gives the earphones a universal look that suits various devices and styles of use. The in-ear design takes up little space, so the model is a convenient choice for everyday carrying and for storing in a bag or pocket. The absence of a wireless module and battery simplifies the construction and eliminates the need for regular charging.
