Stable Connections Even in Crowded Areas

Say goodbye to brief interruptions to your music or calls, even in crowded places, thanks to the optimised touch sensor and antenna in the compact cabinet design, complemented by a Left-Right Independent Signalling System. Enjoy the stable connection you deserve, wherever you are.
Stable Connections Even in Crowded Areas

Unique Antenna Structure

The small product size is achieved thanks to an integration of our Bluetooth antenna and touch sensor inside the control section, while also improving connection stability.With our own proprietary design of the antenna structure, antenna performance is maximised even in a small product cabinet.
Unique Antenna Structure

Left-Right Independent Signalling System

Most wireless headphones receive the smart phone signal in one earpiece, which transmits it to the other ear. This can produce drop-outs and unbalanced sound. Our Left- Right Independent Signalling system resolves this, as each earpiece receives a dedicated signal.
Left-Right Independent Signalling System

Excellent-Quality Call Sound

Six high-performance MEMS microphones are built in a unique labyrinth cabinet structure that can suppress wind noise. Unpleasant noises are reduced and call quality is improved. With the added beamforming technology, the S500W enables your voice to be efficiently transmitted while suppressing ambient noise.
Excellent-Quality Call Sound
