Overview
The JBL Boombox 4 (Black) is a premium portable Bluetooth speaker built for music lovers who want massive, room‑filling sound wherever they go. Packing a powerful combination of two 5″ woofers, two tweeters, and three passive radiators, it delivers bold JBL Pro Sound with deep, thumping bass that’s perfect for parties, outdoor adventures, workouts, or everyday listening.
AI Sound Boost technology continuously analyzes your audio in real time, optimizing output so your tracks stay clear and impactful even at high volumes. With Bluetooth 5.4 connectivity, pairing to phones, tablets, and other devices is seamless and stable.
Designed for all‑day enjoyment, the Boombox 4 offers up to around 34 hours of playtime thanks to JBL Playtime Boost — and its rugged IP68 waterproof and dustproof rating means it stands up to splashes, rain, dust, and sandy beaches without missing a beat.
Advanced features include Multi‑Speaker Connection via Auracast™, so you can link two Boombox 4 units or other compatible JBL speakers for wider stereo or party sound. The USB‑C port also supports lossless audio playback when connected to a suitable source, and the speaker’s replaceable rechargeable battery extends its lifetime and usability long‑term.
Despite its powerful performance, the Boombox 4 is lighter than its predecessor, making it easier to carry to picnics, barbecues, beach days, or anywhere you want powerful, weather‑ready sound on the go.
