I bought this flip 5 thinking I could integrate it into my setup to provide music on the deck and inside at the same time. This speaker is not compatible with previous versions. I refuse to buy another JBL speaker at this point.
No, I would not recommend this to a friend.

JBL Flip 5 has PartyBoost while Charge 3 has Connect. These are two different features of different technologies, which explains why it's not possible to link them together.
So before I bought the flip 5 I had the xb20 (an old ish Sony speaker).The switch was amazing it’s sound is great and the battery the battery is amazing!!! I haven’t charged it up in the last two weeks and it still has half battery it’s an great product but that’s not to say it doesn’t have is problems. So my first problem is that you can a skip a track but you can’t go back and there’s no microphone which mean you will have to use your phone to take calls.
