I bought this speaker about 3 months ago and I absolutely love it you can bring it anywhere with you and always listen to excellent quality audio and the batter life this speaker has is insane how the batter can support the speaker for such a long time at high volume.. overall I'm 18 and was scared about wasting money on a $500 speaker but jt was one of the best purchases ever. Absolutely love it

3rd addition to the Boombox line. Worth it.
I had a Monster Sound blaster from 2016-17. I thought the sound from that boom box would never be matched. As time went on, it lost its ability to keep a charge. I needed another boombox and did some research. After reading a few reviews, I decided to look at JBL's boomboxes. The boombox 2 popped up. I read about it and thought...why not. It had good reviews. Then I heard that there was a boombox 3. I figured it was a little pricey, but, if they were charging this much, they were confident in their product. Man....was I pleasantly surprised. I never heard such solid, tight bass from a portable. They added a subwoofer to boombox 3. Add to that the nice midrange, with crisp, sparkling highs. I'm sold. While the Monster was my introduction to Bluetooth boomboxes...and an awesome one, the boombox 3 took it to another level. If you're willing to spend the extra money, the boombox 3 is well worth it.

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!

Amazing speaker!
I got the boombox 3 just over a week ago and all I can say is WOW! This speaker is amazing for its size, it is alittle bit and heavy but nobody should be complaining considering the sound it puts out. Its literally a portable concert! I own the Boombox 2 also which is still a great speaker. But in my opinion the 3 is better. The bass is very deep and the mids and highs a crystal clear. It gets very loud with no distortion. I also own a partybox 200 and the boombox 3 sounds better with more bass. If you decide to purchase a boombox 3 you will not be disappointed! Remeber, you only live once. Just go for it!
