Introduced in late-2019, the Move was a very Sonos approach to the Bluetooth speaker. It was an attempt to bring the company’s long-standing premium approach to a more portable form factor. Accordingly, the press photos feature a lot of shots of the product on porches and around pools.

Today’s arrival of the Roam, however, takes an even bigger step to full portability, with a smaller, lighter, more ruggedized and waterproof design that puts it more in line with popular offerings from companies like JBL. It’s also priced at a much more palatable $169, more than half the Move’s starting price.
