JBL PartyBox 300 High Power Audio System is rated 4.4 out of 5 by 88.
Rated 5 out of 5 by from Very Impressed! After reviewing several bluetooth chargeable speakers, this always came up as the top review, and boy, what amazing results. JBL has always been a fave for me for PA equipment and subwoofers playing large concerts around the country, and this little gem has some very nice sub sound for its size. I mainly got it to slide behind my seats in my corvette stingray, and now there are even more heads turning. All my neighbors are getting one now too, this was a real eye opener for all of them. We can pair them all together for stereo sound for our parties, which I'm also looking forward to. Kudos JBL, you hit another home-run!

Rated 5 out of 5 by from The party starter. I bought this 2 weeks ago after watching many reviews on youtube of multiple products. Very happy with my purchase overall, great sound quality, the bass literally vibrates my full flat block and takes parties to the next level. Definitely would recommend.

Rated 5 out of 5 by from Best Bluetooth Loud Speaker Ever I purchased this JBL PartyBox a few weeks ago and it was the best thing I did. I compare this PartyBox with the Sony XB7 Extra Bass Audio System. Take my word for it, there was no comparison in sound quality!!!

Rated 5 out of 5 by from Favorite Speaker I've owned I bought this Tuesday and it arrived Friday and immediately walked it to the park and met all my friends and played loud music while they played basketball and had a blast the bass is boomy and clear and the tweeters are super clear despite it being rated for 45 Hz It plays lower and you can still hear the bass clearly just not as loud but that makes sense I wish you could turn the white strobe leds off because for some songs it isn't just the right mood but thats something I can live with I'm here today at school with it we will see how the assistant principles like me toting thus huge thing around but i recommend this to anyone and everyone its the perfect speaker as long as your willing to work a little bit to get it places those who arent get the JBL boombox which is also an amazing speaker.

Rated 5 out of 5 by from ABSOLUTLEY INSANE The speaker is probably the best I have ever bought. The sound quality is amazing and like nothing I have ever heard before. The shape is portable and yet large at the same time . The LED lights are awesome and after not being sure whether to buy this I am so glad I did. Absolutely amazing.

Rated 5 out of 5 by from Flawless! If you’re a fan of the Boombox, then you wouldn’t want to miss this beauty. Best Bluetooth bass speaker ever! (If that makes sense)
