I bought this a few weeks ago and it is amazingly water proof and has great sound for its size though I’m unsure of what the butting underneath the power button is
Overall I am quite happy. The only drawback is it goes into a sleep mode if the power coming in is too low. I have a Windows 10 PC that is connected via Bluetooth. When you adjust the volume on the speaker, it changes the volume setting on the computer. If it goes below 75% for 10 minutes, regardless if it is playing music, it will go to sleep. I played with the settings in Windows with no success. I cannot stop the bluetooth connection from the speaker from controlling the setting on the PC. I can set the PC to 75% or greater, go to the speaker to adjust volume, and the darn speaker will change the setting in Windows. A firmware patch would be great JBL!!!!!
Great sound, horrible quick start guide, NO manual

Just bought this today and took me a while to figure out what all was in the box the way it was packed. Then it took a longer time to figure out how to get started by trying to sift through the lousy Quick Start Guide with tiny icons and print (I had to use a magnifying glass to read it) and dozens of languages (usually just one line of English). No where did it explain how to do the Bluetooth pairing with my phone. Also, it shows you get a USB cable and tries to show where one end of it goes on the Flip 4, but doesn't explain what to do with the other end. No idea how long it will take to charge the battery nor if the battery needs to be charged before first use. Can't figure out how to tell how much charge there is on the battery, so won't know when it is fully charged and will only know it needs charging when it is dead. Doesn't show how device is supposed to be placed (vertical or horizontal) when used. Seems that it can be used as a microphone / speaker somehow, but no instructions how to do that. Gave it 3 stars because it sounds good, but really frustrated that for this much money they can't have decent instructions either in print with the unit or online.
No, I would not recommend this to a friend.
