Good Bass and amazing sound But...
I love this when I first bought it a month ago. Then apparently playing it at max volume causes the Amp and speaker to work hard causing smelling and heating it up. Which I'm confused because if it isn't supposed to go to 100% volume, why make a product that's meant for parties? I love it being at 100% because it sounds AMAZING, but it'd sad to hear I gotta make sure it doesn't burn it and it's just, frustrated me when I heard this, I wish I would've known while looking into them

Best speaker known to man
Got my speaker recently and I can safely say I'll never need to buy another speaker in my life.

Best thing I’ve ever bought!
I have been on the hunt to replace a 10 year old hifi system which seemed to have a great sound and I really struggled to find anything as good in my desired price range. I did a fair bit of research and this product seemed to have solid and consistent reviews and let me tell you, this speaker does not disappoint. It absolutely goes off. I haven’t been able to test it to its full capacity as the room starts to shake around 20% of max volume. I can see some great parties coming up!

I love all the additional features and despite not being overly bothered about the lights, they are brilliant and add a great vibe. A cracking product and worth every penny. If you buy you will not regret it.

JBL wins! They created a mini monster with this!
First off, you know this is something to be hyped about when JBL can not keep this in stock and availability is so scarce it’s going almost double MSRP anywhere online!!!

I’m not going to repeat what everyone else is saying, they are not lying, it’s all facts! I will say I started with getting one of these as a compromise from the PB 1000 regarding price, practicality, and versatility all while achieving decent, potent, accurate, performance sound, and this 310 is a delight! One of these is truly a beast on its own but with it sitting in the one corner of my living room I realized this well crafted machine is so good it needed a partner to get that FULL TWS EFFECT! So I still managed to get a 2nd one from my same source after about a week or two from getting the first one!

Once you hear these in TWS mode (True Wireless Stereo) nothing else will ever be the same! 2 of these at less than the price of the 1000 factoring it’s capabilities in portability, internal battery, IPX4 rating, it’s kind of a no brainer especially if you plan to do things and not let them be stationary objects in your decor, which you can but it’s awesome having that ability and having the 2 is WAY more enjoyable with that TWS sound!!!

So far, so good
Battery lasts. Sound is really good. Clear sound, high quality sound. Bass is deep. Even when outdoors in the woods (at my camp fire). The bass boost gives it even more hit.
My neighbors can hear it 1/4 mile away and tell what is playing clearly. I am rural.
I would Absolutely wish it were twice as loud and just as clear. I may have to order a 2nd unit to achieve that but at $500, that won't be soon.

Awesome PartyBox!! Some room for improvement.
Great sound at a decent price!! Very impressed with the sound that slaps out of this portable speaker. The bass sounds great! Loud and clear lows that you feel with decent mids/highs. I've only had this speaker two days and thinking about grabbing another. I can only imagine how two would sound. My only grip which can be fixed through an update....... Allow EQ adjustments within the app not just for inputs and please allow the option to control lights with a simple steady on. The lights have brilliant color but it would be awesome to just have the lights with a steady on and not flashing around all the time and possibly allow for brightness control.
