It seems Dutch Mediamarkt leaked a video of the upcoming JBL Flip 3, as there has been no official announcement yet.
In contrast to the farting bassreflex port of the previous versions that were not able to produce any bass worth mentioning, the Flip 3 uses the same dual passive radiator design of the Charge 2 and rather looks like a shrinked version of it, but the Flip 3 is claimed to be waterproof with support for wireless pairing of several speakers (maybe up to 3 as the video suggests). I am not quite sure if stereo pairing with 2 speakers is also possible, but this would be great. If the JBL Flip 3 manages to sound as serious as the JBL Charge 2 which is to be assumed as the acoustic design looks very familiar, then the JBL Flip 3 might become a very serious portable speaker and a much better alternative to all this UE junk out there.
It will be available in 8 colors and comes with a handy wrist strap. Of course no information about availability nor price yet, but I guess it will be announced soon and come to the stores this summer.
