Yes, on the current Flip 4 you must download the JBL App and update Firmware that takes up to 15 minutes or so to process and afterwards you can simply turn feature off as an option on the app via iPhone or Android. I too love the product but when your living with roommates, work in office environments or want to simply stay incognito, having the option to say, you know, I can see that it’s on by the light ambient behind the device is always good enough. Unless of course, one may be visually blind. 

It is absurdly loud and sophomoric, interfering with what I am doing with this speaker. Please, JBL, give us a firmware update that fixes this flaw.

I read somewhere that you can download the JBL app on your phone. next connect to the Flip 3. then update the firmware for the Flip 3 so you can get it to connect to connect+ devices.

In my case, this feedback is only produced when the battery hits 100% (staying on charge from PS4 while aux from tv is connected) the only logical explanation I could come up with was a ground loop somewhere. Since the loop would consist of the speaker USB->PS4->PS4 HDMI->TV->AUX->AUX IN back to flip

Hi Mario, I am actually playing guitar through a Tascam DP-008EX digital recorder which has a preamp, but have also tried my OP-1 Keyboard and same result. To be clear the unit does not power all the way down, the power light remains on. The speaker just delays making sound after there has been a silence of 5seconds.

The charger is tucked into the box at the end. It took us awhile to realize where it was tool

I got these information from various YouTube reviews and here's a summary of them: Bass wise, The Flip 4's bass is impressive, it packs a punch but it's not as deep as the Charge 3's. Battery wise. The 6000mah of the Charge 3 is needed for it's big drivers, and to charge your gadgets. In a word, it gives the same battery life span as of the Flip 4, since the Flip 4 has smaller drivers, a 3000mah battery is all that it needs (It will still depend on volume level and music). Loudness wise, the Flip 4 is loud due to the emphasis of treble, but bass levels stay the same. Whereas the Charge 3 is best in max volume, the treble and bass are further emphasized. But in moderate volumes, like 50-75%, the Flip 4 sounds better since the Charge 3 sounds a bit muffled in these volume levels. If you only listen to electronica, heavy bass songs and so on, the Charge 3 is a better choice, but if you are more into Pop, Rock, EDM and so on, the Flip 4 is a better choice. Portability wise, the Charge 3 is a bit of a hassle to bring due to it's size, but unlike the Flip 4, it is much easier to put in your bag due to the small size. Both can be grasped easily by hand. Protection wise, both are IPX7 certified, but take note that the Flip 4 doesn't float unlike the Charge 3 (in my opinion is kinda weird...) so don't drop the Flip 4 in lakes, rivers, the ocean and so on or it'll be difficult to retrieve it. But for me, the Flip 4 is my choice. But it depends on your preferences. Hope this helps!

So which is it Joe? Will it fit or not?
