Ultimate Ears Wonderboom 4 40% Off Best Compact Bluetooth Speaker

Wonderboom 4 hits its lowest price

Ultimate Ears’ Wonderboom 4 is discounted to $59.99 — $40 off — at Amazon, Best Buy, and B&H Photo. This compact Bluetooth speaker, roughly the size of a softball, has become a go-to pick for outdoor hangs, pool days, and light travel because it balances portability, durability, and sound.

• Compact, clip-friendly design with built-in loop for carabiners
• Up to 14 hours of battery life and USB-C charging
• IP67-rated for dust and water resistance, floats and resists drops
• Google Fast Pair for quick Android connections and the ability to link two units for stereo

The Wonderboom 4’s strengths are practical: it’s small enough to clip to a pack for a hike, rugged enough to survive a poolside splash, and loud enough to soundtrack a small gathering. Verge staffers who own the speaker praise its mix of size, price, and durability — and David Pierce specifically recommends the blue color for a pleasant, balanced hue.

Why this deal matters

When a durable, well-reviewed device dips to its lowest price, buyers who delayed purchase often convert quickly. For consumers, the math is simple: you get a travel-friendly, long‑lasting speaker at a meaningful discount. For buyers who prioritize reliability over raw audiophile performance, the Wonderboom 4 checks many boxes.

There are also small decisions that multiply value: buying a second unit for stereo sound, choosing a color that matches gear for gifting, or using the loop and carabiner to free up hands on the trail. Google Fast Pair means Android users spend less time fiddling and more time listening.

What product teams and retailers should note

Promotions like this reveal consumer preferences: demand spikes for rugged, portable audio during outdoor seasons and around gift cycles. Retailers benefit from timed discounts to clear inventory and stimulate cross-sell opportunities (think straps, mounts, or protective cases). Product teams can learn from which features drive repeat purchases — long battery, waterproofing, and easy pairing consistently rank high.
