JBL PartyBox 300 is rated 4.4 out of 5 by 19.
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 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.

Hi Jack, our JBL PartyBox speakers can play in stereo in TWS mode with a distance of 10 meters, making sure that there is a clear line of sight between both speakers and the Bluetooth enabled source for optimal results.

I have doubts about how the treble work, should the three of them work together? or only two depending on the position of the speaker?

Asked by: peluso
Hi there, the JBL Partybox automatically optimizes sound to adapt to placing orientation but for best quality sound, ensure the two tweeters are placed on the upper side of the speaker box. For more information, you can check on the Owner's manual of the Partybox under the manuals and downloads here: https://www.jbl.com/bluetooth-speakers/JBL+PartyBox+300.html

Does the battery gets damaged if speaker is plugged in for most of the time? Since tickle charge is not good but every battery also has certain amount of charging cycles which way would it last longer?

Asked by: Krustins
An average Lithium-ion battery would survive around 500~1,500 charging cycles. Now, according to techs out there who've tested it, it is not ideal to use it from 100-0 in one go, this would degrade the battery's life span badly. There is no harm in keeping the speaker plugged in, what is harmful, is heat. Keeping it plugged in while using it might cause the battery to heat up to such degree that it would also degrade your battery. With these things in mind, what we can advise is - it is okay to leave it plugged in, the charger and the batteries right now are smarter than we think, there is no such thing now as "overcharging". But since heat is something we would like to avoid, unplug it when you use it and charge the speaker a little every time you have a chance to. Lithium-ions takes charge better when done on small frequent charges than going from 0-100. And last note, NEVER flat your battery out.

would the jbl boombox with 2 or 3 charge 3s connected to it be louder than the partybox 300 or better in sound quality?

Asked by: Austin Smith
