OVERVIEW:
Listen to your favorite audio out in the backyard or by the pool with the gray-colored Ultimate Ears WONDERBOOM 4 Wireless Bluetooth Speaker from Logitech. The WONDERBOOM 4's floatable, submergible, dustproof design gives you piece of mind when using it by the pool or at the beach. Use the one-tap Outdoor Boost function to increase the volume when outside to better hear your music, or activate Podcast Mode and relax to an episode with vocals that sound rich and clear. Any type of audio enjoys 360 degrees of sound with crisp and balanced sound with punchy bass, thanks to dual 1.6"" active drivers and a pair of passive radiators.
KEY FEATURES:
Stereo Sound: With an additional WONDERBOOM 4, you can pair the two to either double the soundstage, or to use them for true stereo sound.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $28 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Ultimate Ears products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
