Headphones usams SJ452HS01 stereo wired USB-C white, in-ear earphones

Wired stereo in-ear headphones usams SJ452HS01 with a USB-C connector in white provide wired stereo audio and call functionality for devices with USB-C audio output. The compact in-ear design and included ear caps offer a secure fit for commuting, remote work and everyday listening. The bundled 1.2 m TPE cable and plug-and-play USB-C connection make setup simple: connect directly to a compatible Type-C port without an adapter.

Advantages

A built-in microphone with –48±3 dB sensitivity supports voice calls and hands-free operation. The in-ear form factor provides stable, comfortable wear and passive noise isolation, while the durable selected TPE cable and 1.2 m length balance mobility and reach.

Usage recommendations

Use these earphones with devices that explicitly support USB-C audio output. Some devices with Type-C ports may require specific audio profiles or may not support USB-C audio through the charging port; check device compatibility if audio is not detected. Clean ear caps regularly and avoid exposing the cable to extreme heat or moisture to prolong lifespan.
