Grab the Ultimate Ears Wonderboom 4 for $64.99 before this deal ends
Oct 16, 2026 — 12:32 PM ET
Beach days, pool hangs, and backyard music sessions all call for a speaker that can handle water, dust, and being tossed in a bag. The Ultimate Ears Wonderboom 4 fits that kind of use well, and there’s a nice deal on it at Amazon right now.
You can grab the Ultimate Ears Wonderboom 4 for $64.99, down from its $79.99 recommended retail price. That’s a $15 discount, or 19% off RRP. For a portable speaker built for travel and outdoor use, that price cut makes it a lot more tempting.
The Wonderboom 4 is a compact Bluetooth speaker with a rugged design that’s made for taking on the go. It has an IP67 rating for full waterproof and dustproof protection, and it even floats, which is great for poolside use, beach trips, or even listening in the shower. Ultimate Ears also includes 360-degree audio, so sound spreads in every direction, plus an Outdoor Boost mode for open spaces and a Podcast mode that puts more focus on voices.
Battery life is rated at up to 14 hours per charge, which is enough for a full day out. You can also pair two Wonderboom 4 speakers from a single source for a bigger sound. On top of that, the speaker has a 4.4-star rating, which adds some extra confidence if you’re shopping for a small speaker that can go almost anywhere.
If you want a portable speaker that’s built for water, dust, and outdoor listening, this Amazon deal is worth a look.
