Customer Ratings & Reviews

Tons of bass and great for my daughters softball team. It is 41 pounds and can be bulky for some but overall extemely high quality and crisp sound! Battery has lasted 8+ hours at 60% volume. (50% volume is extemely loud FYI) Bluetooth range is 50+ feet. Havent needed any further yet You feel the Bass!

Great speaker, the family loves the bass and the loudness, great for a karaoke!

I got this for my husband for his birthday. We use this for every party we have or if we’re just cleaning the house we have it panting. It has great volume and is easy enough to move around

I’ve had this speaker for about a month now. So far it sounds great and has had great battery life. I previously bought a Boombox 3 that I used maybe 5 times in a year and it suddenly stopped working . I assume the issue is the battery however, since the speaker was out of warranty, I’m out of luck. The great thing about this speaker is that I can easily replace the battery if I have any issues with it.

This speaker brings the party to wherever you need it. Great battery life and easy sync for pairing devices. Would buy again. Ability to link speakers together is a plus.

Love this JBL Bluetooth speaker. I primarily purchased this model, looking for a party speaker that would have decent bass and low end. The 320 nails it! Especially with the bass boost. The JBL PartyBox app gives you great customization on your EQ, bass boost, lights, effects, and more! I love this speaker so much, that I am going to purchase a second one, and take advantage of the ability to pair them together!

Great portable speaker. Very loud and bass is top notch. The light show is a nice touch. Removable battery is amazing so this speaker will last you a while.

Wonderful sound and lights. Very portable. Exactly what we wanted.

Have had this for a few months and the sound system is great. The battery life lasts about 10-12 hours and it super easy to connect to our TV or iPad. The app is user friendly. One downfall is the connecting the MICs for karaoke nights the plug is in the back and it is a little bulky too many entries.

Excellent sound, easily portable with extendable handle. I use it in my man cave with a tripod. Has an app you can download on your Apple iPhone.

My husband brought this to the lake as we go every other weekend and it has stayed charged the whole entire time we are out there for 8 hours would definitely recommend great quality sound as well

Extremely surprised by the quality sound that comes out of this speaker. LOUD DEEP BASS!!! Super easy to use. Battery life is outstanding even when using the speaker at max volume. Very very happy!!!!

I was hesitant to pay over $500 for a portable speaker. However, I am glad that I did. This speaker has excellent sound and the battery lasts for a very long time. I’ve used it all day at the beach and it still had charge left for the following day. Highly recommend.

Best large speaker! We haul this around to our travel ball games and it always works great! Battery last all day and has great sound!

JBL done us good on this one. Sound is solid. Bass is the cherry on top. Replaceable battery..... it's a win win all around. Easy

Booming sound. Bright lights. Just an overall perfect speaker! Great addition to my party sound! I have the partybox 110 and now the 320. Love how it has wheels and a handle for easy mobility.

Awesome speaker puts out a good and clear punch. Purchased it for 4th of July weeked and was loud enough to make poping fireworks a party. Have used it for several othe get togethers and the sound filled up my living room like a night club. Sounds amazing for the size of the spaeking and its portability makes it perfert to take outside by the pool and the sound effects were cool too had my kids and guests laughing especially the classic DJ airhorn lol. I would say the only downside is the JBL app and not being able to download or add my own sound effects

I really like this speaker a lot. I like that it is rechargeable. The sound is amazing. It really has good bass and adjustable bass settinga and the lights are changeable and adjustable and color changing

Perfect for parties: Designed to energize large gatherings, from backyard BBQs to full block parties. Simple setup: Connect via Bluetooth, queue up your playlist, and let the speaker do the rest.

I purchased this for the sole purpose of bring it to parties during my masters degree. This did not disappoint and I got the task of always bringing a speaker. In a room of 40 people, this speaker will still stand out. In addition of being loud, big, good sound quality, the battery really last a long time. We've used it continuously for 2 nights at 50% volume and I still have 40% left after a 3 day trip. All in all, used for around 12 hours combined at 40% volume and still has 40% battery left.
