The verdict

The Panasonic RZ-S300W is meant for the listener who wants her earbuds to do a little bit of everything. Alexa integration means you can easily respond to incoming messages, check notifications, and more, while the IPX4 rating makes these earbuds ready for almost any workout. That said, these are feature-sparse relative to offerings from Samsung, Google, and even Sony. Sound quality and comfort are the main reasons to buy the RZ-S300W.
