The 360-degree video above shows, in a somewhat chaotic manner, JBL’s successful attempt to achieve a world record for ‘Most Bluetooth Speakers Playing from a Single Source’ (yes, there’s a category for that…) by successfully playing more than 1000 JBL Flip 4 Bluetooth speakers simultaneously from a single media source.

Sure, you’re unlikely to be trying that at home. But as part of ongoing celebrations surrounding JBL’s 70th birthday, it does show how multiple units of the new Flip 4 can easily share their tunes to an ever expanding level, while also bumping out the previous record-holder, rival UE, which had linked a mere 208 in Paris last year.

The other trick of the Flip 4 is impressive waterproofing, not just the usual splashproofing but full IPX7 immersion-proofing (and one of JBL’s video for this did make us laugh, so we’ll link to that below).

JBL is a company that spans the entire range of audio, from its Synthesis bespoke home theatres through the highest end of two-channel audio right down to portable and Bluetooth speakers. And the lesser breed of music making no small market — at the recent Sydney Harman (not to be confused with Sidney Harman) launch they told us that JBL has shipped some 40 million of its various portable speakers between September 2012 and May 2017.

The Flip 4 is one of its mainstays, a 175mm-long portable Bluetooth speaker powered by a 3000mAh rechargeable Li-ion battery that offers 12 hours of continuous audio playtime — that’s just a little longer and larger than the Flip 3, with the same battery capacity but longer quoted play time (and 3.5 hour recharge time).

And where the Flip 3 was splashproof, the Flip 4 is immersion-proof, entirely sealed, with a passive bass radiator at each end and two 40mm active drivers along its length, covered with waterproof fabric material available in six colours – Black, White, Teal, Grey, Red and Blue.

It can work as a speakerphone, with built-in noise and echo cancelling speakerphone, and can link to the Siri or Google Now assistant in your connected smart device. Indeed two different devices can connect via Bluetooth simultaneously, taking turns to play music.

And then there’s that JBL Connect+ technology that can wirelessly link “more than 100” (but apparently 1000) JBL Connect+-enabled speakers together.

The Flip 4 is available now, RRP$149.95.
