I’m a truck driver and I use my speakers all the time . I stopped using them before the update because they would go in and out . I just updated and I do see improvement on the sync, before the speakers would go out and come back on but would not be in sync with the picture. That problem looks like it is fixed. The problem now is they still go in and out , I use them with my iPad and I really love the speakers. I hope the developers can get this together and as the updates come out I will give my opinion on them . Also note they do not stay synced when you play them together. One will drop out and one will play on and off.I give two stars for the small update. Update august 5 . I will give five stars now because I haven’t had any problems with the connection for the last month. The app is working fine at this time.

The JBL app is… well it’s available for the JBL speakers. I was going to give it 2 stars, but they recently added the option the adjust the EQ on the speaker. I suppose I’m a little sour because I used to use the Ultimate ears app with the MegaBoom speaker. With that app you could turn on and off the speaker (which was super handy if you were laying in bed and wanted to crank some music in the moment, you didn’t have to get up and find the speaker, or if you didn’t know where the speaker was 😆) it never lost Bluetooth connection, never had to find it in my phone Bluetooth settings. If other Ultimate Ears speakers were on, you’d simply “drag” the speakers into your profile and they’d instantly start playing what you were playing… good for party’s. I understand you can do this with the JBL speakers as well (I own 3) With that though, the JBL speakers are WAY better (in my opinion) than the Ultimate Ears speakers, but the JBL app isn’t very good… it often doesn’t find the speaker that I’m currently playing from, and same for other speakers that are awaiting to be linked together… I almost never use the JBL app, I just run my speakers manually (which works really well) If anyone from JBL reads this… AWESOME speakers, but the app needs work when compared to others.

So I’ve had the speaker for about 2 years now and it by far is one of the best speakers I’ve ever used. But the only reason I’m giving it 4 stars instead of 5 is because it’s had a bunch of problems with charging, EVEN after I replaced the battery a couple days later it started doing the exact same thing it was doing before I replaced it. Now it’s working perfectly fine all the sudden and it’s only staying “charged” on the 1 out of 5 of the dots for charging and that’s what it was doing before I replaced it and I go on this app and it says it’s that low. Idk I take super good care of it always have and it’s still took a weird turn and idk if two years would be long enough for it to have anything happen to it but who knows. Please help idk if it needs an update but if so please send that haha. Thank you that’s my review. Send me a new JBL charge 4 or upgrade me to a charge 5 or trade mine in and upgrade me to the charge 5 and I’ll raise my rating but idk if it’s that worth the extra stars.
