We bought this item directly from JBL as we purchased a Boombox 2 from amazon that only lasted 8 hours while playing music. It was not even at full volume. We thought purchasing from you we could trust we were getting a quality product. We were excited about the Boombox 3 and it did sound fantastic. Unfortunately it only lasted under 8 hours and the volume was at 75% while playing music. We were extremely disappointed and returned it. If we are going to spend close to $500 the product should live up to the hype you claim it has.

Battery light needs improvement
I've been using my new Boombox 3 for 4 months now. It sounds great! The battery only lasts 6 hours on max volume. It last about 12 hours on 3/4 volume and 18 hours on half volume.

Here's three massive improvements that are required, in my opinion.

1. Make the bottom flat all the way from end to end and widen the bottom so that it is more stable. It rolls around all the time. If you even slightly bump it, it becomes a rolling pin.

2. Put the LED battery/charging light on top of the unit by the on/off button and volume buttons. Why did you think it was a good idea to put it on the bottom of the speaker where you can't see it?

3. Make the LED battery/charging light a digital readout. Level 0 through 10. You have a limited idea of how much battery life is left until the light bar turns red. At that point you're down to 15 minutes to an hour left of play time depending on the volume you're at. That's also providing you pick it up and check the light periodically.

Old software was better
I just upgraded the jbl Boombox 3 to Software version : and I don't like the bass quality anymore. With this new update he no longer has the classic club jbl bass. Maybe the bass is a little stronger now but I prefer the sophisticated bass typical jbl than before

I just got the Boom box 3 and it's sad to say that it doesn't live up to the 24 hours of play as advertised. I charged my Boombox 3 over night as it states it takes 6.5 hours to charge, now I bought this speaker because it say it supposed to last 24 hours but here I am in the 7th hour of play time and the red light is already flashing. It sounds amazing, I don't even have it but less than half way because I'm at work... But I am disappointed in this for dying so early compared to the promise of 24 hours. Wish there was something that could be done, $500 for this I could have just kept my JBL Charge 4 for this.

A fair improvement in sound, crappy battery
The sound quality is a definite improvement over an already good speaker. The addition of the midrange speakers add a definite depth of field. The only downside is the battery. They apparently used the same battery as the Boombox 2 because I get 25% more life out of a 2.5 year old Boombox 2 battery than a new one

Beware Battery Life!
I purchased this last week (7/16/23) before our beach trip. This speaker lasted roughly 5 hrs on 3 separate occasions (beach and pool). Audio sounds amazing but you'll be left hanging midway through the party. Not worth $$$$
