Etón is not a brand I'm familiar with and a quick look through the company's current products and Wikipedia page doesn't reveal too much aside from the fact that its products are aimed toward outdoor use and emergency preparedness. However, its new Air4 speaker is a very striking departure from all of that. It's a high-quality indoor speaker with a price that oscillates between $499 and $599 depending on where you look and it supports streaming through both Chromecast and Apple Airplay. (Note: Eton calls it Google Cast, but Google phased the name out in favor of Chromecast a long time ago.)

The Air4 is an 80W speaker with two 10 x 15.2cm woofers and built-in 25mm tweeters.
