The Wonderboom 4 is Ultimate Ears’ latest ultra-portable pool-friendly speaker, and it sounds far better than you’d think, given its modest size. In our early tests, the Wonderboom 4 has deeper bass and clearer midrange performance than any speaker we’ve tested in its held-in-the-palm-of-our-hand size class. We’re also fans of its design, from the mesh covering made partially out of recycled plastic to the giant volume buttons that are easy to press and impossible to miss. Ultimate Ears says the Wonderboom 4 lasts up to 14 hours per charge, and its IP67 rating means it can be fully submerged underwater without being permanently damaged. Though it probably won’t be because it floats. Don’t skip this deal if you need an ultra-portable speaker that can still pack a punch.

Why Trust PopSci

Popular Science started writing about technology more than 150 years ago. There was no such thing as “gadget writing” when we published our first issue in 1872, but if there was, our mission to demystify the world of innovation for everyday readers means we would have been all over it. Here in the present, PopSci is fully committed to helping readers navigate the increasingly intimidating array of devices on the market right now.

Our writers and editors have combined decades of experience covering and reviewing consumer electronics. We each have our own obsessive specialties—from high-end audio to video games to cameras and beyond—but when we’re reviewing devices outside of our immediate wheelhouses, we do our best to seek out trustworthy voices and opinions to help guide people to the very best recommendations. We know we don’t know everything, but we’re excited to live through the analysis paralysis that internet shopping can spur so readers don’t have to.
