Boombox 4

Reviewer verdict

Across 13 YouTube reviews, the JBL Boombox 4 earns an Index score of 3.9/5, ranking #44 among Bluetooth Speakers. Reviewers most often praise its sound quality, features, design, while the most common criticisms concern sound quality, design.

The JBL Boombox 4 is widely praised for its powerful, room‑filling sound and especially its deep, punchy bass, a theme mentioned by many reviewers across the sample. Reviewers frequently note the redesigned driver setup (two woofers, two tweeters, three passive radiators and a rear passive radiator) and higher wattage output that deliver loud, clean playback with clear vocals and crisp highs. Features like two bass boost modes, a removable battery, Bluetooth 5.4/Auracast support, USB‑C powerbank/audio, and a seven‑band EQ in the app are repeatedly highlighted as useful modern upgrades. The build and design — lighter weight than the previous model, IP68 durability, improved handle/feet, and subtle LED lighting on the passive radiators — are also commonly praised for portability and toughness.

Critics commonly point to sound drawbacks at extremes: some reviewers report distortion at maximum volume or when pushing deep bass and describe the speaker as directional rather than 360‑degree. Design complaints focus on the replacement of the metal handle with plastic and the white color option staining easily, while battery criticisms include real‑world shorter runtimes at high volume, a fiddly battery swap process and costly replacement batteries. Other recurring negatives are the limited onboard light customization, removal of the 3.5 mm aux jack and lack of PartyBoost/older JBL compatibility, which some reviewers see as reducing value for the price.
