This thing sounds good from low volume all the way to when its cranked. It will beat almost any speaker out there, and trust me I know because we use it to tail gate and we never hear any other peoples music except for ours. Bigger is better with this JBL PartyBox 300!

Good speaker if you can get it on sale. I like the colors that show when the music is playing and the sound is pretty good. I think it should be able to get louder given its size, but its good enough for listening to music in the yard.

Nice size to move around plus 2this better than one fun with the light show going and playing the music party boxes LL

They fill the room with sound no problem.... and easy to connect and move around as needed..

Awesome Speaker. Got on a black Friday deal. Ended up being cheaper than the boombox sounds great have a good bass

great sound battery life is very good and the price is good as well i highly recommend it for anyone who enjoys good sound

Christmas gift for my husband and he is thrilled with it , the bass lights and great loud sound makes for a happy costumer.. Thanks

excellent option to put music in a meeting,It takes up little space but its sound volume and quality are very good

Great sound and bass. I love the quality of sound you get from the speaker.

I got the speaker on Black Friday for $300 and it sounded pretty good but it is quite big and a pain in the butt to move. After watching videos about it on YouTube I found that the partybox 100 sounded better in comparison to the 300 sounds muffled ( it does have a little better bass but that’s at high volumes). So I returned it and got the 100 and it sounds really good (it has great clear sound with nice bass that can shake the room) and is super easy to carry and move. I would highly suggest getting 2 party box 100 or even save some money and get one party box 100 over the 300 or get the 310 but it’s a bit pricy rn.

It’s being so fun using this speaker. Plenty loud and the lights are fun to watch. Totally recommend.

This is an awesome speaker!!! If you want a good sounding speaker with great bass then you need to get this! Would recommend to anyone.

Best portable Bluetooth speaker I ever had. The sound is amazing and the bass is over the top.

Amazing sound and base. I bought 2 of them and they synced pretty well and delivered very nice output.

Ok this speaker is the best speaker I have every bought loud fantastic bass lights are fun I love this thing

I would imagine this speaker was louder for the price. It’s a good speaker, good sound, good bass but not really loud at all. It’s a little bit on the heavy side as well

This speaker has great sound and my kids have a blast with it. They love the lights and the bluetooth works great.

Great sound quality! Awesome speaker for $400. Love JBL. Syncs to your phone immediately. Won’t regret the purchase!
