Customer Ratings & Reviews

product is good. easy to use, cordless and good sound quality

This thing is awesome! Nice loud bass, wireless connectivity, and a light show, if so desired. The only negative is as others have pointed out, after a while, you lose the ability to adjust the volume. If you turn Bluetooth off and back on, it will work again. Other than that, fantastic!

Large speaker for sure! Sound is good so far, but not “really” a solid bass boost in my opinion. The button can be clicked on or off for that. That said, when it gets warmer out, it will be outside with me on the patio. Perhaps the bass boost will sound a bit different, maybe better, outside. Have a few JBL products, so it is a good brand and I have been pleased with the smaller JBL speakers I have. I’m sure this one will not disappoint! Cool lighting effects as well.

Very loud and easy to connect to. Absolutely no complaints with this speaker. I’ve used it for parties and it makes it so convenient and easy to move the party when it’s started to rain, you just pick one speaker up instead of an entire system.

I have tried to purchase this product all during Covid lockdowns I am actually glad I waited I was able to catch it at $299 the sound is awesome from bass to quality & clarity it’s perfect for parties or just listening at home

I will always buy JBL products good quality and rugged.. been a fan of JBL since Sophmore yr high school.. this Party Box produces a good balance of Highs and good Tight Bass... highly recommend to anyone looking to bring any Party to Life.

Not so good. Because it is heavy Not good for soft listening. Good for louder listeners.

This speaker has great sound and a great volume level. However the speaker goes to sleep even when plugged up to A/C. This requires you to walk over and turn it back on pair your device again. I bought this speaker to be the audio out for my google home, but since it goes to sleep it will not stay connected to the network like my Bose Speakers.

This thing bumps! Haven’t had a party big enough where this speaker can’t provide. Exceeds my expectations, especially when it’s plugged in, as it is able to draw more power that way. A little hefty, but to be expected from something so powerful.

The sound quality on this speaker is great and with the addition of the light feature makes this purchase amazing.

Nice sound and great base. Really good for my party sounds and even on my karaoke magic sing.

This bad boy puts out some sound! A bit heavy but if you don’t have to move much it’s great

I love this system, been eyeing it for a while and finally bought it. I have so many of these portable speakers from JBL and they are def worth it, knock on wood I’ve never had any issues. This system is not heavy and I love the lights.

This was a Christmas gift for my son. It was his favorite gift!!! It is everything it says it is!!! I would totally recommend it. The sound is amazing. He plays his playlist from his iPhone and it is so clear. He loves it.

Pretty good bass and good voice quality. Overall sound quality is excellent!

very loud and sounds awesome the light show cool and comes with a car charger Must have

I love my JBL PartyBox 300 Speaker! This speaker delivers crisp, clear sound and the light effects is sure to bring the party. Although, I wish the speaker had wheels but the easy grip handle is okay for transporting the speaker.

I enjoyed this product. However I ended up retuning it because it’s way to heavy to make it portable to use outside. Unless your going to leave it in one spot don’t go with this because it’s very heavy. Sound quality is amazing!

Awesome speaker. Produces a really big sound. Heavier than expected.

Great for outside by the pool, patio, or just in the house. Sound is amazing. Actually better than what I expected. Glad we made the purchase. Highly recommend.
