The S500W and S300W promise “supreme call quality” with a premium microphone in a specially designed housing that minimizes wind noise. Each earbud connects individually to your device rather than to each other, which should improve sound quality over older wireless earbuds. The Panasonic Audio Connect App will let you change sound modes and customize additional settings, including your voice assistant of choice. Both pairs of earbuds are compatible with Siri and Google Assistant, and support for Alexa will be added in a future update. 

The RZ-S500W sell for £169, while the RZ-S300W are £109. Once they hit American shelves, the RZ-S500W will cost $199 at launch and are available in white or black. The RZ-S300W will be only $129 and comes in black, white, or green. In January, Panasonic said these earbuds were scheduled for a June release in Europe, but a US launch date has yet to be announced.
