i bought this less than a year ago, and the eight months the speaker battery has barely lasted more than a couple hours, despite charging for days. it will not charge above 2/5, and dies constantly. i have to keep it plugged in to use it at all, and even then it will die within minutes unless it’s been plugged in for a few days. the sound quality is great, but this speaker does not work at all how i was expecting, and i would not have paid this much money for it if i knew it was going to be worthless within a year.

I got this speaker as a Christmas gift. I was so excited about it. I have never had a speaker as loud as this. I have previously had the Go 4 and this is a huge improvement. I was kind of disapointed of the Bluetooth version as it has Bluetooth 4.2. But I love the audio jack. It is compadible with a lot of devices. I wished that JBL still kept the audio jack on their speakers. But the sound quality is excellent. The battery seems to last forever. But it also seems to take forever for it to charge. Overall it is a great speaker. I actually thought it had a tweeter but I was confused when I only heard sound coming from one side of the front of the speaker. Then I just found out it does not have a tweeter. This is fine with me. a little grateful because this is so loud for just a driver and two radiators. The app is kind of disapointing. I thought there was more you could do on the app like the Go 4, which has an equalizer and playtime boost. this you can really only turn on and off the feedback tone and update the firmware. But It does not have connectivity issues like the Go 4 because it randomly disconnects from my chromebook. The charge 4 does not do that. It's connection is strong. And if you are having issues. Connect it maually using an audio cable. This is just an awsome speaker.

So far I have been extremely impressed with the speaker. Great sound for such a small device and the battery has lasted a long time
