Product details
The True Wireless In-Ear Headphones S300W offer a stable connection, even in crowded places. Thanks to their minimalist and compact design, you can enjoy your content undisturbed anytime and anywhere. The special positioning of the six high-performance MEMS microphones suppresses wind noise. Unpleasant sounds are reduced to ensure excellent call quality. With conventional True Wireless headphones, it can happen that the Bluetooth connection is temporarily interrupted, especially in crowded areas. However, the Wireless In-Ear Headphones RZ-S300W feature an innovative antenna arrangement around the control sensor that significantly improves the Bluetooth connection. The separate transmission of signals for the right and left channels further enhances the stability of the Bluetooth connection. The RZ-S300W earbuds utilize an innovative antenna arrangement around the touch sensor for a noticeably improved and more stable Bluetooth connection, as well as a much more compact design.

Very good100/100
For around 88 euros, the Panasonic RZ-S300W are an attractive alternative to the Apple Airpods, which currently cost around 129 euros. The Panasonic earpieces have a convincing build quality, even if the charging case is only equipped with a plastic folding mechanism. The battery life of our test device is also impressive...

Sound quality is impeccable for the price range, and operation is simple and almost intuitive...
