JBL Go 4 4.2W RMS Portable Bluetooth Speaker IP67 Waterproof

Clip the loop through a bag strap or hook it on a railing, and the JBL Go 4 is already doing its job — this is a speaker built to just come along. At 190 grams, it barely registers in a bag, and the redesigned integrated loop makes it genuinely easy to carry rather than something you fumble with at the last minute before heading out.

Small Speaker, Real Presence

Despite the compact size, the 45mm transducer and 4.2W RMS output deliver JBL Pro Sound with punchier bass than the dimensions suggest — not room-filling, but plenty for a picnic table or a small backyard gathering. Frequency response runs 90Hz–20kHz, enough range for vocals to stay clear without the low end going muddy.

Water and Dust Don’t Slow It Down

With an IP67 rating, this is the kind of speaker you stop worrying about near a pool or at the beach — splashes, sand, a stray wave lapping too close, none of it matters. You don’t think about the rating until you’re at the edge of the water and realize you don’t have to move it.

Battery That Keeps Pace

Playback runs up to 7 hours on a charge, and Playtime Boost can stretch that another two hours by tuning performance for louder, crisper output when you need it. USB Type-C charging takes about three hours start to finish.

Connectivity for Bigger Moments

Bluetooth 5.3 handles the everyday pairing, while Auracast lets you link up multiple compatible JBL speakers when one just isn’t enough — or pair two Go 4 units together for proper stereo sound. The JBL Portable app adds EQ customization for anyone who wants to tune highs, mids, and lows to taste. Built partly from recycled plastic and fabric, it’s a compact, competitively positioned speaker for grab-and-go outdoor use.
