Who wins on what

Ranked by what users actually praise

Overall Impression

Sound quality and battery life stand out as major strengths. Commenters highlight the bump to 10 watts of output compared to the WB3's 5 watts, delivering noticeably better bass and volume for its size. One user got about 18 hours of playback at 30-40% volume, while another still reports strong performance from an old first-generation Wonderboom after years of use. New owners note surprising sound quality and volume straight out of the box, and several say it beats competitors like the JBL Flip and Tribit Stormbox Mini in direct comparisons.

Hardware upgrades bring the WONDERBOOM 4 up to modern standards. The switch to USB-C charging and Bluetooth 5.3, up from the WB3's 4.2, is welcomed by longtime users upgrading from earlier models. Buyers also praise the tank-like build quality, with one owner recalling dropping their original Wonderboom off a roof without damage. Another calls the current model 'built like a tank,' though notes the volume buttons are stiff and hard to press. Overall the physical design earns consistent praise for durability and placement flexibility around a room.

App support and included accessories are common sources of frustration. Multiple commenters angrily report that the speaker does not actually connect to any companion app, contradicting some reviews that claimed otherwise. Buyers also note that a charging cable is no longer included in the box as of 2026. One user experienced dropped Bluetooth connections and no memory of stereo pairing settings between two units, calling the setup process tedious. Others report crackling or distorted audio in Standard mode with certain tracks, though it clears up in different sound modes.
