Rock-Solid, Interruption Free Bluetooth Connectivity

Make dropouts on your music and calls a thing of the past. Bluetooth 5.0 delivers ultra-stable wireless connectivity, even in crowded areas, to ensure your favourite tracks and important phone calls are uninterrupted.
Rock-Solid, Interruption Free Bluetooth Connectivity

Left-Right Independent Signalling System

Most earphones use a relay system where only one earpiece receives the signal and transmits it to the other. This can cause connectivity issues and result in an unbalanced sound.
Left-Right Independent Signalling System

Impossibly Compact Design, Without Compromise

A breakthrough in technology allowed us to integrate the Bluetooth antenna and touch sensor while improving connection stability. The uncompromising approach to reducing the overall size and weight of the earphone ensures maximum comfort and convenience.
Impossibly Compact Design, Without Compromise

Compact, Convenient & Ultra-Comfortable

Weighing in at approx. 4g per earphone, the S300’s take convenience to the next level. Comprehensive research on the length and angle of the sound ports are combined with four different earbud sizes ensuring all-day comfort.
