Dual Hybrid Noise Cancelling

High-Performance Dual Hybrid Noise Cancelling combines the technologies of Feedback and Feedforward Noise Cancelling with the analogue and digital processing of captured noise.

The S500W wireless earphones thus offer the perfect conditions for you to fully immerse in your audio content.
Dual Hybrid Noise Cancelling

Excellent Call Quality

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

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 S500W earphone’s 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 S500W wireless earphones’ small size was achieved thanks to an integration of our Bluetooth antenna and touch sensor inside the earbud’s control section, while also improving connection stability.

With our own proprietary design of the antenna structure, antenna performance is maximized even in a small product cabinet.
Unique Antenna Structure

Left-Right Independent Signalling System

Relay-type System
Previously, audio data was transmitted in a relay-type form from one earbud to the other. This method consumed more power and was vulnerable to sound interruptions.

Left-Right Independent
With our new method, audio data is transmitted from the smartphone to both wireless earbuds simultaneously, ensuring low power consumption and stable transmissions.
