The JBL Go 4 Blue looks like it belongs next to water, and with an IP67 rating it can actually live there. This is the bright blue version of JBL’s smallest Go speaker: 94.3 x 75.7 x 42.2 mm, 0.19 kg, protected against dust and temporary immersion. JBL lists a 45 mm driver delivering 4.2 W RMS with JBL Pro Sound tuning, up to 7 hours of music on a charge plus up to 2 hours with Playtime Boost, Bluetooth 5.3, and Auracast so a second Go 4 can join for stereo. It is a speaker for swim days, boat trips and family afternoons at the pool.

The blue finish by the water
Blue is the colour most people picture with a pool or the sea, and the JBL Go 4 Blue matches swimwear, beach towels, kayaks and paddleboards without effort. On a white pool deck or pale sand it stands out clearly, so it is easy to keep an eye on when children are moving around. A mid-tone blue hides light sand and water spots better than white, though dried salt can leave pale marks; a rinse in fresh water clears them. The colour also suits a bathroom with blue or grey tiles, where the speaker often ends up for the morning shower playlist.
Waterproof and dustproof by design
JBL rates the JBL Go 4 Blue at IP67. In plain terms, dust cannot get inside to damage it, and a drop into a pool or a splash from a wave does not end its life. That makes it one of the few speakers you can leave on the edge of a bathtub, by a pool or on a boat deck without worrying. JBL does not publish a floating claim for the Go 4, so do not count on it bobbing on the surface; tie the loop to something if you use it near deep water. Dry the charging port before connecting the cable.
One speaker, or several with Auracast
Buy one JBL Go 4 Blue and it plays alone; buy a second Go 4 and JBL says the pair can play in stereo, with left and right channels split between them. Beyond that, Auracast lets you link multiple Auracast-enabled JBL speakers for bigger sound. This is handy at a family gathering where one speaker sits in the majlis and another on the terrace. Connection to your phone is over Bluetooth 5.3, and multi-point connection means a phone and a tablet can both stay paired, so switching between them does not require re-pairing.
How the 4.2 W output sounds in real rooms
The official figure is 4.2 W, with a frequency range that JBL lists as 90 Hz to 20 kHz. That lower limit tells you what to expect: kick drums and bass lines are present and punchy for the size, but the deepest sub-bass you hear from a large speaker is not there. Where the JBL Go 4 Blue works best is close listening: on a desk an arm away, in a bathroom while you get ready, on a picnic blanket in the middle of the group. JBL calls the tuning JBL Pro Sound, and the free JBL Portable app lets you shift the balance with presets or your own EQ.
Who the JBL Go 4 Blue suits
Families who spend weekends at a pool, a beach club or a villa garden get the most from this colour: the speaker sits on the edge of the water, survives splashes from the kids and goes back in the beach bag wet. Swimmers and divers who play music before and after a session, people who go out on boats or jet skis around the islands, and anyone who likes the shower as a music room all fit the profile. It is also a cheerful gift for a boy or a teenager. If you want a speaker that blends into an office, the black or white Go 4 is the quieter choice.
Who This Is Not For
Look elsewhere if you need a conference or call speaker: the JBL Go 4 Blue has no microphone listed by JBL. A single unit plays in mono, and its 4.2 W RMS output will not cover a big hall or a loud outdoor crowd. It has no wired input and no charge-out port for your phone. JBL’s maximum operating temperature is 45 °C, so keep it out of a hot car and away from midday sun on the dashboard. The box contains a USB-C cable but no charger.
