One thing ruins all good impression
The speaker is good in sound - I previously owned HK Go&Play and this one sounds not a bit less beautiful.

However there is one thing that Extremely Ruins the experience!

When you listen via cable and your music track is in low volume, the speaker goes to what can best be described as "sleep" almost immediately - 5-10 seconds. And then it requires a higher volume than before to "wake up" and start playing again, and it also takes time. I can't even describe how irritating is that when you are listening to a classical music track - they very often have long loud and almost silent periods, so you just started to listen and then in the middle of the song - voila, your speaker just stops playing because it considered your track not loud enough - but it was loud enough for you to hear! Or one more case from my life - when you decide to practice your guitar and connect boombox 3 to a guitar pedal. One second you played a chord then spent few seconds adjusting your fingers to a new one - and the chord is simply not sounding because the speaker went to sleep during that pause, so you need to play something for next ~5-6 seconds before you start to hear what you are playing again.
The described behavior is not present when you connect via bluetooth not via cable, but for cable I can describe it with only one word - AWFUL! Don't buy it if you plan to listen via cable!

JBL, this _needs_ to be fixed!
Few minutes of battery life or some silent noise whispering in the background are not worth the loss of continuous playback. This "sleep" interruptions are awful!

Massive speaker that will rock your party!
First of all the design and the processing quality are well refined and the orange spots on the logo brand and under the handle are just impressive. The speaker is indeed very heavy and it's definitely not an item that you just move from one to another spot quickly despite of carrying it longer ways. The speaker has the latest Bluetooth 5.3 version, so you get the state of the art. But when I try to start playing a song, almost every time the first half second the song gets cut off. Even when I have the latest software update installed. The battery life is just excellent and the recharge works with no hassle. You can even charge your own device over the USB-A port with around 10 W. The app looks fine, of course you can disable those annoying sound prompts for example when you turn on/off the Boombox. The latency is great when you watching movies or series with you audio over the speaker, so no sound delay in this case. And of course it sounds good in this area. Now let's talk about the sound quality in general. I would say the speaker sounds the best when you are listening to EDM, Hip Hop, Rock and Pop music. The highs are fine, some details in comprehensive songs don't show up unfortunately, the mids are audible and present, but miss some clarity directional, the bass on the other hand is just awesome but I would put it down to -1 at the EQ settings. The mids and high +1, respectively. Then it sound the best in my opinion. Regrettably you can only select each (highs, mids, bass) between -2 and +2, so no in between option or more settings available. For that price it just too expensive at the moment in my opinion and I would only recommend it to people that are really enjoying listening to music at higher volume and have the option and location to do so. And of course people who want to have a private party. When you are also enjoy listening at lower volume levels, you absolutely can, but don't expect the best balanced sound quality.

Packs a Punch
This will get everyones attention, neighbors beware. It is loud and is the best sounding product I have seen that you are able to carry around. Bass, Mids, Highs are all crisp and clear. I do have a large 2 acre lot, if I am up late at night, I will turn it down slightly. Easy to connect, super long range, i can walk all the way back to my house, and it's still connected for great range. Long play time, the 24 hours is accurate. My only knock is that it may be a little large and heavy for your liking, but if you can get past that, you will not need anything else.

Amazing product as always JBL. Thanks for bringing us this.

Great unit all around
After I purchased the Sony XG500, I returned it due to the sound and looked at a Boombox 2 at the store, They didn't have any available so I went searching for the Boombox 3, I am so glad I did.
I'm really pleased, not only with the bass (the Sony had good bass too) but the highs and mids were equally impressive and didn't get drowned out by the incredible bass of this unit.

It gets quite loud but luckily doesn't lose much quality at the higher volume levels.

I wish they got the app better, it needs a battery percentage rather than a bar and the graphic eq doesn't really do much.

Overall, I like the design, it feels super sturdy, looks great and performs even better. Yes, it's pricey comparative to others on the market, but I'm still happy.

Insane Sound!
The sound is still perfect even at full volume. Only the weight is a small drawback. The Boombox 3 is just fun, good mood and puts a big grin on everyone's face. The neighbors should be very tolerant, because with that you can entertain the whole street!

Awesome boom box with awesome bass & sound
This boom box has nice sound quality that is perfect for entertaining 35 x 45 foot backyard area. Clear sound from every angle in area. Bass is crisp & specific sound sharpness for light soundong instruments whic allows for true musical entertainment. Now while it is a bit heavy, it is worth it for the experience.
