A patio speaker needs to survive spills, splashes, and the occasional drop. This comparison puts four portable Bluetooth speakers from Ultimate Ears, Sony, JBL, and Bose side by side on water rating, battery life, range, multi-speaker pairing, and warranty.
How We Chose
We compared four portable waterproof Bluetooth speakers from JBL, Bose, Ultimate Ears, and Sony, all available on Amazon and priced between $110 and $160. We left out cheaper speakers from little-known brands. The speakers are not identical. They differ in size, in the water rating (IP67 or IP68), and in what each listing states, so where a value was not stated on a manufacturer page we say so. Every spec and warranty cell in the table comes from the manufacturer’’s own page and names it. The Sony cells come from Sony Canada pages and the Sony help guide because Sony’s US site could not be read, and the Ultimate Ears cells come from Ultimate Ears and Logitech pages because Ultimate Ears is a Logitech brand and Logitech publishes its warranty. This is a researched comparison, not a hands-on test, so we make no claims about sound quality or how well any of them holds up beyond what each listing says. Prices are Amazon prices checked in September 2026 and can change.

Check Price on Amazon →Our Take
If price matters most, the Ultimate Ears BOOM 4 is the cheapest and the only one here that says it floats. If long battery life matters most, the JBL Charge 6 lists the most hours and can charge a phone. The Bose is the most compact of the four and the most expensive, and the Sony sits in between with a bass button. All four have similar water ratings on paper, so the choice comes down to battery, size, and price. We did not test any of them.
