About this Custom JBL - Boombox 4 portable waterproof speaker:
- The all-new JBL Boombox 4 is bigger, bolder, and better than ever, delivering powerful JBL Pro Sound with deep, thumping bass. Two 5-inch woofers, two 0.75-inch tweeters, and three passive radiators (two circular, one racetrack) work together so every track hits harder and sounds cleaner, while AI Sound Boost analyzes the music in real time and adjusts the sound to give more power with less distortion, even at full volume. Two Bass Boost settings let users switch between deep and punchy bass to match the mood.
- The classic Boombox design gets a fresh upgrade here — larger, but lighter, so it travels easily to the beach, the block, or the backyard.
- It's IP68 waterproof and dustproof, so weather is never a dealbreaker, and delivers up to 34 hours of playtime (28 hours standard, plus 6 more with Playtime Boost).
- Auracast™ lets users stereo pair two Boombox 4 units or link multiple Auracast-enabled JBL speakers to the same playlist. A USB-C port supports lossless audio playback for listeners plugged into a laptop or compatible source, and the battery is user-replaceable in three simple steps (spare battery sold separately).
- The housing uses post-consumer recycled plastic and recycled fabric for the grille, and it ships in FSC-certified paper packaging printed with soy ink.
- At this price and size point, the Boombox 4 works best as a premium, high-visibility reward rather than a mass giveaway. Its large front grille offers generous branding real estate, making it a strong co-branding piece for a company logo alongside JBL's own.
- It's a natural fit for top-tier client and VIP gifting — a rugged, daily-use item that keeps a brand in view every time it comes out for a beach day, a barbecue, or a weekend trip.
- On the internal side, it makes a memorable milestone gift: a work anniversary reward, an employee-of-the-quarter prize, or the grand prize in a sales incentive (SPIFF) for a rep or team that blew past target.
- Its rugged, outdoor-ready build also makes it a standout grand prize for summer contests, sweepstakes, or trade show booth drawings — the kind of prize that gets people to actually stop at the booth.
