Best price ever: The Ultimate Ears Wonderboom 4 Bluetooth speaker is half off at Amazon
The price-tracking data cited by Mashable places it as the lowest recorded figure for the SKU.

The Ultimate Ears Wonderboom 4 has dropped to $51.44 on Amazon, according to Mashable, marking a 48.6% cut from its $99.99 MSRP and a record low per price tracker camelcamelcamel. The move puts the palm-sized Bluetooth speaker at the lowest bracket of the sub-$100 portable market, a segment PCMag's 2026 budget guide treats as the practical entry tier for buyers who need durability over smart features.
Discount mechanics
The listing trims $48.55 off the retail price and is live in the blue colorway. The price-tracking data cited by Mashable places it as the lowest recorded figure for the SKU. No coupon code, bundle, or trade-in is attached; the discount is a flat Amazon cut. At this number, the unit undercuts most competing IP-rated portable speakers in the same size class, including the Anker Soundcore Motion 300 referenced by PCMag at its typical street price.
What the spec sheet covers
The Wonderboom 4 ships a 14-hour rated battery life per charge, a 1.2-meter drop resistance rating, and an IP67 ingress rating that covers full submersion up to 30 minutes. Output is single-driver mono with a passive radiator and a dedicated outdoor boost mode that lifts the upper-mid range for open-air listening. Mashable's reviewer notes the sound profile is well-rounded and reaches usable volume, but flags the absence of a companion app for EQ or firmware control. There is no multipoint pairing or LDAC support listed; the unit runs standard SBC over Bluetooth.
Where it sits, what to watch
For buyers prioritizing drop and water durability in a sub-100-gram form factor, the data points to a direct value pick over the JBL Flip and Tribit StormBox lines currently competing in the same Amazon search results. The trade-off is software: no app, no EQ, no stereo pairing firmware updates since launch. Stock at the discounted price has historically thinned within 48 to 72 hours of past lows, per Mashable's coverage. The main risk for a buyer is timing — the $51.44 figure is tied to the live listing and not a permanent price reset.
