#SoundOnStay connected. No matter what.
The S300W true wireless headphones provide stable connectivity to reduce interruptions even in crowded areas and enable smartphone content to be enjoyed comfortably.
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.
Unique Antenna Structure
The small product size was 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 maximized even in a small product cabinet.
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.
High-Quality Call Sound
Applies high-performance MEMS microphones built-in unique noise reduction (labyrinth cabinet) structure that can suppress wind noise. Unpleasant noises are reduced and call quality is improved.
Compact Size with Perfect Fit
The rounded body fits comfortably in the ears even for long use. A massive amount of 3D ear data has helped design the angle and length of the sound ports.
