Crystal Black Bluetooth 6.1 Headset

The SOEWIOU YYK-520 is a new in-ear wireless headset finished in Crystal Black. It targets drivers, office workers and mobile professionals who need a lightweight, cable-free solution for calls and media. The design prioritises secure fit and all-day comfort for extended wear.

100-Hour Total Battery Life

A 500 mAh charging case delivers up to 100 hours of combined talk or music time. The earbuds alone run for 10 to 12 hours per charge and reach full capacity in 1.5 hours. An LED digital display on the case shows remaining power for both the earbuds and the case itself.

CVC 8.0 Noise Cancelling Microphone

The unidirectional microphone uses CVC 8.0 technology to suppress ambient sound during calls. A dedicated mute button on the headset silences your voice instantly for confidential moments. Passive noise isolation from the in-ear fit further reduces background distraction without active electronics.
