Massive sound. All day long. We just made our most powerful portable Bluetooth speaker even better. The iconic silhouette of the JBL Boombox 3 has a bold update featuring a sturdy metal handle with silicone grips, twin sidecaps, and waterproof and dustproof signature fabric. It’s been redesigned inside too, added with an improved subwoofer unleashing much deeper bass and massive JBL original pro sound, all with lower distortion. And 24 hours of play time takes you all the way from your morning workout to a late-night hang with your friends. And for sound that’s practically limitless, instantly connect multiple speakers with the JBL Portable app.
Q: Can you play this while it is plugged in and charging or is it on battery only?
A: Our JBL Boombox 3 can be played while the speaker is charging. There's no harm in using the unit while it is connected to a power source. Our products have PCM circuits that manage the charging of the battery. However, if you'd like to save energy, unplug the speaker.
A: Our JBL Boombox 3 will be almost twice as loud as it has more speakers that produces more wattage compared to the Xtreme 3. The JBL Boombox has 1 subwoofer(80watts) + 2 midrange drivers (80watts) and 2 tweeters (20watts). While the Xtreme 3 has 2 woofers(50watts) and 2 tweeters(50watts).
Q: Thinking about this or the older 2 version for half the price. Is the 3 worth 200 bucks more??
A: Yes, the 3 is louder and has better bass. Also the old charger was annoying with the big block.
Q: Does jbl boombox 3 has microphone outlet?
A: No it doesn’t have a dedicated mic input. However, it is technically possible to use a wireless battery powered mic plug-in module with an aux adaptor tip that downsizes from the standard 1/4” mic tip found on most adaptors. Unfortunately the volume of your voice with a wireless mic that comes with such an adaptor will be rather low compared to a PartyBox or Karaoke Box/PA system. Also, there is no Mic specific volume function on the Boombox to increase the sound of your voice. I am not sure if any wireless mic modules and mics have their own physical volume buttons that could increase the vocal sound through the boombox, but that may be worth looking into.
A: With it cranked up it doesn’t matter no distortion on high res lossless tracks that will play for 9-10 hours full blast.
Q: Do you sell a replacement charging cable for the JBL WiFi Boombox?
A: Yes, its just a regular radio cord. Can get anywhere
Q: Does a single unit play in stereo or is this only possible when matched with a 2nd speaker?
A: Thanks for your inquiry. Our JBL Boombox 3 plays in mono when using a single unit, and stereo sound is only achieved when it is paired or PartyBoost with another speaker.
A: The USB port on our JBL Boombox 3 is for charging other devices and does not function as an audio input. It can only connect via Bluetooth wirelessly.
