Product details

The S300W True Wireless in-ear headphones provide a stable connection - even in crowded places. That, and the minimalist and compact design, means you can enjoy your content anytime, anywhere without interference.
The special positioning of the six high-performance MEMS microphones suppresses wind noise. Unpleasant noises are reduced to ensure excellent call quality. With conventional True Wireless headphones, the Bluetooth connection may be temporarily interrupted, especially in crowded places. In the RZ-S300W Wireless In-Ear Headphones, the innovative antenna arrangement around the operating sensor ensures a significantly improved Bluetooth connection. The separate transmission of the signals for the right and left channels additionally increases the stability of the Bluetooth connection. In the RZ-S300W earbuds, the innovative arrangement of the antenna around the touch sensor ensures a significantly improved and more stable Bluetooth connection and a much more compact design.
