WIILGN OY131 Single Ear Bluetooth 5.2 Headphone 51g 300mAh 20h

Lightweight Single-Ear Headset for Calls

The WIILGN OY131 is a mono Bluetooth 5.2 headset weighing 51g, built for professionals who spend hours on calls. Its single-ear design keeps one ear open to the surroundings while the boom microphone captures voice with CVC 6.0 noise suppression. The 30mm driver covers a 20Hz-20KHz frequency response at 105±3dB sensitivity for clear audio.

Simple Pairing and Dual Charging Options

Pairing is straightforward with Bluetooth 5.2, offering a 10m wireless range and LED connection indicators. The 300mAh battery delivers 8-20 hours of operating time and 200 hours standby after a 2-hour charge. A charging base provides a second docking method, reducing wear on the direct port. The mute function and volume controls sit on the earcup for quick access during calls.

Check Bluetooth Profile and Wearing Preference

Verify your device supports the headset and hands-free profiles used for calls and music streaming. The over-the-head band with a concave cushion on the non-ear side suits left or right placement, but users who dislike any headband pressure should note the 220g total weight. Microphone impedance is 32Ω with a 50Hz-16KHz response optimised for speech rather than music fidelity.
