"True Wireless" in-ears with active noise cancelling are not only available from the smartphone specialists in California – although their model names are much more memorable. Japanese manufacturers have always been particularly familiar with filigree electronics in the smallest of spaces. In May, Panasonic will be launching two affordable models with sophisticated technology: the top model RZ-S500W (180 euros) works with microphones mounted both outside and inside and with digital and - for particularly low latency - analogue signal processing. In addition, the beam-forming technology suppresses ambient noise during telephone calls. Panasonic indicates the battery life with 6.5 hours plus two refuels from the charger case, making a total of 19.5 hours. In the even smaller model RZ-S300W (120 euro), it's even 26 hours in total. Both models are splash-proof and transmit the Bluetooth signal separately for the left and right channel directly to the respective ear cup. They are also compatible with the voice assistants Siri, Google Assitant and Amazon Alexa. The RZ-S500W will be available in black and white, and the RZ-S300W additionally in mint green.
