    I just received my JBL Boombox 4 through UPS in just 3 business days. Not only was my product shipped to me fast but the box was much bigger than I expected. After testing the sound on this boombox I realized this boombox sounded a lot more like a kicker I had installed in a car. This boombox is off da wall, Seriously, all these comparisons they advertise on YouTube are garbage. No more comparing because if you ain’t got JBL, you ain’t got a boombox. Not only does this boombox have superior sound, but it has bass that bumps just as loud as my JBL 1300 & it’s portable. You got to get this boombox, there is nothing but pure bass & you get every dollars worth & even more for what you bargain for. JBL4LIFE.

    This speaker has decent power. Sounds decent battery life. If you played a full power last about 5 hours If you are conservative with the power could last longer overall, an ok product dust proof water resistant, convenient to move around, if you are interested in moving a speaker around, this will be a great product.

    Great sounding speaker, the louder It plays The better it sounds I found to get the best clarity Between base & vocals is to download the app. And use the EQ. Battery life is good and I like the flexibility of being able to pop out old battery and replace it with a fresh one when on the go.
