For almost a year I couldn’t use this app to use with my speakers to play them in stereo. To there credit they do seem to be addressing issues with the app. I can now do stereo playback. However, one thing still bugs me, the app does not show an accurate representation of just how much battery life your speakers have, it constantly says 100%. This wouldn’t be so frustrating if it wasn’t for the fact that the speakers don’t show up as a Bluetooth device connected on the iOS front page where you see you battery status for other devices like your watch or Apple Pencil. I seriously hope they address this. Knowing just how much charge your devices have is crucial.

Pros: when this app is (was) working, it makes playing more than one portable speaker easier than trying to manage them through Apple Music. Cons: when attempting to update the firmware as prompted, both JBL Flip 6s abruptly started blasting the most horrendous, harshest, literally ear piercing noise while I was sitting about two feet away from both of them! That noise was so loud and so bad that I had to overcome my instinct to cover my ears with my hands to try and hard shut down the speakers. That took a couple of minutes simply to get both speakers turned off and the stop the hellacious noise. The volume control was not working, I was in panicked shock. No exaggeration here - we are talking literally hearing damaging harshness at a dangerous volume. I wish I had a way to convey how bad this actually was. Perhaps to help illustrate, my dogs literally fled the floor of the house that I was on yelping and whining, cowered for another 20 minutes and avoided that room for several days. Intelligent animals! For the past 6 weeks since, I have been afraid to attempt another firmware update, but perhaps fortunately - it will not progress. After multiple, multiple attempts the update seems stuck on 0%. Recap. Aside from the cons above and the fact that I absolutely cannot recommend this app, everything‘s great!

Thanks for ruining my listening experience with the latest firmware update, taking something that worked perfectly and breaking it. The audio cuts in and out constantly now. And you CAN’T use stereo mode unless you use THIS useless, bloatware app. Before you could just turn your speakers on and select partymode and they’d be in stereo. Now when you do that without the use of this app, you have both speakers in mono. I love the sound quality of these speakers but the hassle of being forced to use a separate app just to listen in true stereo mode is extremely annoying. Fix this with another firmware update or give us a way to roll back to previous firmware versions. This app is totally useless otherwise because you can’t use the EQ in partyboost, so why create an inconvenience to your customers of having to use this app just to put your speakers in stereo mode? Very poorly thought out.
