Portable power for travellers who need serious sound on the move.
JBL’s Xtreme line has always been the brand’s “work hard, play hard” speaker, the one you sling over your shoulder for a weekend away or park confidently in a meeting room when you need punchy, room‑filling audio. The Xtreme 4 continues that legacy with more refinement, more stamina, and a design that feels purpose‑built for business travellers who want reliability without fuss.
Design & portability
The Xtreme 4 keeps JBL’s familiar cylindrical silhouette but feels more grown‑up this time: cleaner lines, a sturdier carry strap, and a finish that looks smart rather than sporty. It’s still chunky — this isn’t a speaker you slip into a laptop bag — but it’s light enough to travel with and tough enough to survive airport lounges, hotel terraces, and the occasional outdoor meeting. The IP67 rating means it’s dustproof and waterproof, which is reassuring when you’re working on the go.
Sound performance
Where the Xtreme 4 really earns its name is power. The bass is bold but controlled, the mids are clear, and the highs stay crisp even at higher volumes. It easily fills a hotel suite or small boardroom, and it’s equally comfortable handling conference calls or background playlists. JBL’s updated tuning gives it a more balanced profile than previous generations, making it a strong all‑rounder for both work and downtime.
Battery & features
Battery life is excellent – up to 24 hours depending on volume and the built‑in power bank is genuinely useful when your phone is running low between meetings. Bluetooth connectivity is stable, pairing is instant, and the new Auracast support means you can link multiple compatible speakers for larger spaces.
The JBL Xtreme 4 is a confident, capable travel speaker that bridges business and leisure effortlessly. It’s not the smallest option on the market, but if you want robust build, impressive sound, and all‑day battery life, it’s a dependable companion for life on the road.
