Okay. For starters if you want something with some good sound and good bass compared to the normal mid range speakers, this is it.
This thing is bigger than your usual speaker. I was looking for something with some more bass than the current JBL Extreme 2 I have, and this blew it out the water, of course over $150 the extreme price. Your able to download the JBL app so it helps you control a few EQ settings, including bass, but why lower that with the price tag on this thing.
I live in an apartment and after a few days of use, I had to make a hard decision and say I’ll return this because to listen to it at its full potential, the walls vibrate and it’ll just be a complaint issue for me or my annoying neighbors. lol. Even if I drop the bass down fully using the app, it is just right to an extent, but with those settings, I’m basically at where the JBL Extreme 2 I have is, with maybe 10% more bass.
So overall I’m returning this because I don’t go out enough to use it, but it was a hard decision because I love the bass. This thing at a little outside hangout or beach would make it seem like you have an actual system with you, but for me, $500 for maybe a few outside uses a year is not worth it due to my living conditions. But if you use a lot outside for work or etc., have a home where neighbors wont be an issue due to the space next to each other, then this is it for you. Who knows, I have only had less than a week, maybe I might just keep it to have so when I do have those times I go out or we have family gatherings or beach days, then this speaker will be it. But for my general in home use in an apartment, I’ll stick with my Extreme 2 I’ve had for the last year. That is on sale for $200 right now because they are on the 3rd version. Extreme 2 is greater than Extreme 3 because it allows you to answer and talk through your phone on the speaker which #3 does not, just FYI.
Battery life is great, also depends on how loud you use it. I opened it a few days ago at 60% and only at 40% with a lot of use/testing.

This speaker is an absolute monster when it comes to bass, this boombox has the same bass as an entire subwoofer because it has one! This speaker has a 3-way speaker system, 1xSubwoofer 2xMidranges 2xTweeters stacked on top of the midranges, this speaker is the best for indoor and outdoor use, good bass with the best sound quality you will ever hear. You can also take advantage of its EQ settings in the app made for this speaker, 10/10 highly recommend!

Okay let start with unboxing, it got very cool artwork on the outside of the box with all the jbl logo and people jamming out, getting inside everything was packaged very well you get a nice cloth for the speaker, taken it out was super easy but however it so heavy 15 pounds for a speaker, i turned it on in the car and played some music at 50% and i fell in love with it right away with the new speaker setup in the boombox 3 and it probably by far the best sounding speaker the bass is so deep and powerful that it was litterly shaking the car mirrors i was blown away the mids were super crystal clear and the highs were a little but too high but it was clear, the build quality on the speaker is super premium which is what you would expect on a high end portable speaker, the fabric is super tough does not flex at all, it does get little dust in it super easy though but it is water proof dust resistant making it a great speaker for outdoor! When your outdoor you dont need to worry about your phone battery going low because it has built in usb ports to charge your phone! Definitely worth buying the boombox 3

Capable of producing decently full sound in large rooms and outside, with a moderate battery life at mid-high volumes and a decently solid waterproof rating, this is a great option to use around the house and on the go. It has a decent connection range to match the sound it can throw. It weighs a little more than many portable speakers, but it’s not inconveniently heavy in most situations for me.
