Best Speaker on the Market!!
Bought this speaker about 3 years ago and it has been through soooo much and has endured through it all like I just bought it yesterday. Best sound quality and bass! Feels like I am at a concert everytime I play my music 🎶 ❤️

Thanks for your feedback on our JBL Boombox 3. The published up-to playtime is the maximum battery time you will get when listening at background levels. As the volume increases, and depending on the source material, the playtime will be reduced. Please try charging your speaker to 100%, and listen to music without bass boost and at low volume. If the speaker lasts close to playtime, the battery is working fine. If you get less than 90%, it is possible there is an issue with the battery. Please contact us for further assistance.

Disappointed
I have a jbl charge and 2 flip speakers but are great however not impressed at all with the boombox3 really disappointed in tbe volume it's not really much if any louder than my charge. It does have more bass but volume sucks definitely not worth the price if I was buying i would just go with the charge is the best bang for the buck!

I'm Impressed, Overall Sound Quality is Great
The Boombox 3 sounds great once your get the EQ settings dialed in. It can go bass heavy, but when playing in an open area, this works. I Played music at moderate levels outdoors for 7 hours and it had plenty of battery life left. It is very easy to connect to Bluetooth.
