The company says both sets of buds are good for home, commuting and exercise with an IPX4 splash-proof rating that means you shouldn’t need to worry about rain or sweat. Both pairs of buds also have voice assistant compatibility with Google Assistant or Siri, so you’re good to go whether you use an iPhone or an Android device. Amazon Alexa support is on the way, too and the buds’ mics also have you covered for hands-free calls.
If it’s battery life you’re most interested in then the cheaper RZ-S300W will suit you. They lose the noise cancelling but Panasonic claims they last 7.5 hours on a full charge while the case charges them three times from a full charge of its own, meaning you’ll get 30 hours from the package.
The RZ-S500W will get you 6.5 hours and 19.5 hours overall comparatively. Enough for a round the world flight, but less given the power needed to juice the noise cancelling which you’ll probably want on a flight anyway.
Add to that an ambient mode for letting sound in when you need to be aware of your surroundings and Panasonic’s new sets of buds seem to tick all the boxes. But until we test them, there’s no way of knowing how good the sound or noise cancelling is.
You can buy the RZ-S500W now in black or white, or the RZ-S300W in black, white or green.
