    • Best speaker so far!
Style: Speaker Color: Black
I own other JBL speakers and products so I researched the 710 and 720 models before making a purchase. I didn’t want to buy something and then feel like I needed more. The 520 model meets my needs perfectly. It’s loud, clear, and easy to connect to other speakers. The app also makes it convenient! The charge holds quite a while as well. ... show more

    • Upgraded from the 310, and WOW!
Style: Speaker Color: Black
Like so many have said before me, the 310 lead to the purchase of the 520. At the time the 310 was the biggest speaker you could buy from JBL that had a battery making it truly portable. New for 2025 the 520 is the next step in the Partybox lineup. Still battery powered and portable, and of course heavier than the 310. The 520 makes almost twice the power @ 400W RMS, with the 310 @ 240W RMS. The 520 does not leave me wanting more. I also chose the 520 because it fits under my desk, the 710/720 are at or over 40" so they are not as compact as the 520. As for the sound, at very-low-to-low volumes the sound is similar to that of the 310, but the right ear can tell there's something more special with the 520. It's when you start turning up the volume does the 520 begin to outclass the 310. Also keep in mind, no matter which you own, 310/320/520, they must be plugged into the wall to get that max power (RMS). Those using the JBL app will find familiarity but some unique features for the 520. It adds some new sound profiles and a 7-band customizable EQ. The 310 had a very basic EQ. I tinkered with the EQ and found a personal setting I love and this thing absolutely rips! The 310 will play your content loud, but the bass will fall off as you near the top in terms of volume. I don't find that the case with the 520 at all, as the volume goes up the bass stays right there. I was bummed when I read the tweeters on the 520 were smaller than that on the 310 but after listening to them side-by-side, you'd never know it, and it's a non-issue at this point. I'm listening to it as I write this review and it brings a huge smile to my face. So far (in any JBL portable speaker review) the battery life is extremely good, lasting me all week, playing my content 11 hours a day. I leave all the lights/visuals off. The added bonus is the battery is removable and you can buy extras and swap them out as needed, if needed. As for value, that's tough one, this speaker is not cheap and comes dangerously close to the 700-series in terms of price but not in power. The 520 and 720 are priced too close for their power differences, if space is of no concern, consider the 720. Thankfully I got this during the Black Friday deal and that lessened the financial blow. If I had to do it again at full price I might have had to think of that a bit more. ... show more

    • Great multi-use speaker!
Style: Speaker Color: Black
Absolutely phenomenal speaker. We use it for just about everything at our school. Outside for music when the students are dropped off, calling names for pick up, in the gym for basketball games, etc... The handle and wheels are fantastic, and having XLR inputs is a great touch. I only wish it had an XLR output to another speaker instead of an 1/8th inch connector. But, I also understand my use case is probably different than most. Also, the lights, they're fine. We don't really use them. A neat little party trick. Over all, can't praise this enough for sound quality, portability, and useability. Fantastic investment. ... show more

This is by far the best speaker I have ever owned!! The bass is unreal! Sound quality is fantastic no matter what level you have it at! The only thing I wish it had was a way to connect to it over wifi!

    • Jbl 520 partybox
Style: Speaker Color: Black
I own a 310 Partybox and now the new 520 it is a great speaker good bass and sound. It is a bit louder then the 310 however it does need to be up in the higher volume levels to get the good sound. At lower volume the bass is a little flat sounding even on the high setting. I would say at 50% volume the sound is very good and again at 75% volume. The price for the 520 is steep so it only makes sense to buy it if size is a concern? Otherwise you can get the monster JBL 720 for less when it is on sale and have 800 watts vs 400 from the 520. ... show more
