PHOTO: Handout If you’ve been looking for a music speaker to bring to the pool or simply chill at the park, the new Sonos Roam just unveiled today might be something worth checking out. Weighing just 430 grams, the cylinder-shaped speaker is also rated IP67, which means it can be submerged in water with a depth of up to 1 metre for up to 30 minutes. Fine even if you drop it in the pool, but don’t go swimming with it, of course.
