This works perfect - sound, somewhat portable and Bluetooth. We used first night on our street outdoors. Lights are a good feature. It can get loud. I’d have no hesitation buying again if you need some volume in a semi-portable BT speaker. JBL has a solid history in speakers, BT speakers and high end audio.

I have read that people can't seem to get these to sync into stereo mode. I have had zero issue with that. I think they may be trying to get them both to connect with bluetooth and you do not need to do that. Just one, then follow the instructions. Now to the review. These things are freaking AWESOME. I have 12.5 acres of land and I can cart these things wherever I want and set them up and have great tunes whether I am sitting at the bonfire, on the pool deck, in the back pasture, etc... Additionally, having the ability to RCA cable out to a separate powered speaker, stand back. These are a perfect. I have always been a fan of JBL and this is exactly what I needed as I was tired of cords everywhere. Clean sound, good bass, very responsive.

Jeeze oh pete's! This thing is freaking loud! I regret buying for my husband, he likes listening to music really loud anyway, but now, OMG!! I bet we'd be getting complaints from the neighbors if they didn't have one too! LOL. It's fantastic, really. The lights are cool, the portability is fun, you can take the party on the road!!

JBL 300 very simple to set up. Speakers are powerful and music enjoyable. Box holds charge considerably well for hours of endles, it appears, playing. Great value for price. I enjoy streaming music on this device as well as playing thumb drive music on it. Get one, or two :).

I like the sound quality of this speaker. Has good bass. I’d say the only negative is it’s a little on the heavy side. It’s called a portable speaker but I’m not sure how many times I’ll be moving it around, as for me it’s not that easily portable that I was thinking it would have been. Was thinking it would have been easy to take and travel around with. Other than that it sounds good! I enjoy the lights on it too. I bought my kids a microphone and they love to sing karaoke on it

I wanted something loud to stream music to and this thing is loud and has plenty of thump where you want it. It is wireless as needed and has a massive battery life. I tried a sonos system but it does not work with blue tooth like this bad boy does so this one definitely wins out for my needs. If you want something loud and portable look no further.

I was debating wether to get the 100 or the 300. Soooooo glad I got the 300. Although it’s a little heavy (not a problem for me) it has amazing sounds, the bass is also GREAT as well. My family and I use this speaker mainly outdoors and it’s amazing!!!

This was a gift for our teenage son. He loves it. Sound is great, Bass is good. Battery life so far has been as expected. he loves not having to worry about finding an extension cord or plug. He can't wait until COVID is under control and he can have his larger gatherings of friends again.

This speaker is amazing with great sound and long lasting battery life. It is Bluetooth so you can be across the garage or room and still control the party without having to go over where the speaker is to change the songs or volume. This is a must have if you entertain.

Easily the best and biggest wireless speaker I've ever owned. Super nice sound that carries a good distance. From hip hop to dubstep to rock and metal, all sound amazing. Long lasting battery as well. The different light settings are a cool feature as well!

Really good speaker. Really loud and clear. I just like turning it on and leaving the bass on. It kinda heavy so both hands would help. Would buy this all over again

Great sound and nice bass. Love the fact that you don’t have to carry the power cord with you. battery lasted all day for me. You can also add a Mic and guitar. Also play music from a thumb drive. Well worth the money.

Great Bass, battery lasted the duration of our party (5 hours) nice, loud and clear.
Inside house it's sound is amazing, clear at 100%
Even though it's plenty loud... I like enough to consider getting another to link up.

This has made. A perfect addition to our outdoor entertainment. The lights are fun and there are a couple different settings, including off if preferred. The bass sounds great and the highs and mids are nice and clear.

I got this for my 11 year old daughter. This thing ROCKS, she and here friends Love it. If you don't like clear, loud, bassy, music, this is probably not what you want to get your kids. My buddy and I like to rock it as well. My buddy is going to buy one for himself. It has a rechargeable battery, so you can take it Anywhere. It comes with a 12 volt charging cord to charge/run in a vehicle too.
