Gmoore . 1 month ago
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.

We have this Boombox and have had it for over a year. We just bought it for my daughter and son in law who just bought a new house with a nice backyard for entertaining. The speaker is fantastic and my husband literally uses it every day. He will listen to music on it while he is getting ready for work then when he gets home he goes out to our backyard and listens to music again. The battery life is really good. He only charges it maybe once every two weeks. He has really enjoyed the speaker so I'm hoping my daughter and son in law enjoy it as well.

JBL puts the BOOM in Boombox3

BlindGeek007 . 3 months ago
I use the JBL Pro Series when we do our outdoor event, and they always give excellent sound. I have a JBL XTreme2 Portable, and it gives excellent sound. So, when I saw the Boombox3, I knew I had to have it. It totally did not disappoint. Big stereo sound out of a portable device...

JBL Boombox3 Portable Bluetooth Speaker FAQs

Is there a way to buy a back up charger
Mufutau55 . Nov 17, 2025
How do you Reset Boombox 3 to Factory defaults
Answer from Customer Support2 months
Thanks for your question. To reset the JBL Boombox 3 to its factory default settings, turn on the speaker, press and hold the "Volume +" and "Play" buttons for more than 3 seconds until the speaker turns off. You may need to 'forget' the speaker in your phone/tablet's Bluetooth settings to pair it again.

which is louder...boombox 3 or boombox 4 ???
Bface . Dec 26, 2023
Does it have mic in?
Answer from Customer Support2 years
Our JBL Boombox 3 doesn't have a microphone input to connect external microphones. If you're looking for a speaker with built-in microphone input, we recommend checking out our JBL PartyBox Series speakers like the JBL PartyBox 310 or JBL PartyBox Encore Essential.

Not able to Connect to charge 4
Answer from Customer Support2 years
Our JBL Boombox 3 and JBL Charge 4 have different features that are incompatible with each other. The JBL Boombox 3 has the PartyBoost, while the JBL Charge 4 has the Connect+. Each speaker must exclusively connect to another speaker with the same feature.

How many total wwatts is the boom box 3?
Dec 5, 2023
itunes on PC recognizes JBL Boombox 3 but states it is incompatible with current version of Itunes. Is there a fix? I upgraded software. NO improvement. I will have to return as I run my home audio through itunes PC airplay.
Answer from Customer Support2 years
Thanks for reaching out. We'd like to let you know that this is a known issue as Apple is phasing out iTunes and is replacing it with Apple Music which can be used on iOS and Mac OS but there is no Windows alternative as of the moment. If you need more help, please contact our customer support.

Is it possible to use for karaoke?
Answer from Customer Support2 years
Thanks for your question. Our JBL Boombox 3 isn't suited for karaoke since it doesn't have a microphone input. We recommend our JBL Partybox On-the-Go as it comes with a pre-paired wireless microphone and an additional microphone input that works best for karaoke. You can also tune the bass, echo, and treble on the speaker's panel to achieve the best vocal and music settings.
