JBL - PartyBox 310 - Black JBLPARTYBOX310AM (Renewed)

Likes: Although this JBL Partybox 310 was “renewed”, the only way I could tell was by the orange “feet?” on the sides that where a little dark because the unit was most like used in a horizontal configuration. Kudos to the seller for packaging it as if it were a brand new product. It was clean and came with everything that it would have in the box if you bought it new.Sound: 8 out of 10! Very good for a portable unit. I listen to a lot of Hip Hop, EBM, & Techno, so a few of the deep bass drops (probably about 10% of them) were not reproduced like on my dedicated home theater subwoofer, but it sure did hold its own with a lot of the music my wife and I pumped through it! Including some Metal & 80’s hair bands! I use the “Punchy” bass setting for Metal, Rock, ect., but “Deep” for Hip Hop, Rap, R&B, EBM, Techno, and other electronic music.Lights: 8 out of 10! The light show is pretty cool, but I do wish it had more preset options in addition to the 5 it has in the app (yes, it has an app so that you can remotely control it with two separate Bluetooth devices/cell phone's simultaneously). There is a manual setting but I personally like their presets in the app.USB: 7 out of 10! The ability to throw a bunch of MP3’s or WMA’s on a USB “thumb drive” (do we still call them that?) is very cool, but with some caveats. 1. The drive MUST be formatted in Fat32. It will not read exFat, and I have not tested NTFS. I also have not tested it’s ability to play WMA’s. A lot of my music is purchased through iTunes and I really wish it read AAC files, but in my testing it does not (the manual tells you precisely what files it will read).App: 8 out 10! I really like the additional “DJ Sound” sound board built into the speaker and the app. I like using the “Horn” when something that’s really pumping is playing! Not to mention it has a 1/4 Microphone Jack in the back but I have not yet tested it. One wish I have for this app is that it would tell me the name of the song playing from the USB drive. Song file information would be a great addition! With Bluetooth you can always switch to the app on your device to see what the name of the song is, but not so with USB playback. If they could somehow add that via a firmware update that would be awesome!Portability: 10 out 10! Honestly, I haven’t taken it anywhere because I really like it in its current pristine condition! However, the battery life from my heavy, heavy use was anywhere from 6 to 7hrs with lights and “Bass Boost” + the EQ in the app set at full bass. I don’t know if they replaced the battery with a brand new one, but I’d say I’m pleased with the battery life so far. What I love most in addition to the battery life is the retractable luggage handle and the wheels. Now that’s pretty cool for helping to move it because it’s not a light unit!Seller: 10 out of 10!!! The unit came one day early and arrived in excellent condition! Apologies for not writing this review sooner, but I really wanted to put this “renewed” unit through its paces, and so far it’s exceeded my expectations. Even my wife (the harshest judge ever) gives the seller AND the unit two thumbs up!!!

I got this for $330 Nov 2023, and I think it was an amazing deal. My intended use for this was 50% to use in an indoor pool room because of the IPX4 splashproof rating, and 50% outdoors with my wife and I or with friends. Turns out I now even use it indoors while I'm working, or when hosting people, or just for general music anytime. It's just that convenient and good sounding.For the pool area I haven't had any issues with splashing or humidity. It's been great to use in there. Outdoors I haven't had any issues with water from rain either, but it's only lightly rained on it once.I did not update the software as I've heard that can ruin the bass. The software has functioned without issue for me. It's has adjustable EQ, powerful bass and does rattle my walls in my house. The sound carries well inside. I really only use it at like 25%, sometimes 50% inside my house. Outdoors it's loud and is more than enough if it's a smaller gathering. For real, unless you're a DJ, it's perfect outside too. My neighbors will absolutely compaln if I run this even at 50% outside. However, for a real outdoor party scene where you're a DJ being paid to shake the earth, I can see how you might want two of these, or two of the next model up.The battery lasts a long time. Idk how long because I tested it and used it for hours, for days in a row, and it didn't get below 40%. That was good enough for me since I can plug it in whenever.The carry handle does feel a little loose, it's awkward to lift vertically, and the wheels have low clearance, but that's really not an issue at all. It rolls well for being so heavy and powerful, and I am capable of lifting it fine if needed.Overall I'm extremely satisfied with this purchase.

I'm the guy that usually skips past buying the cheap offerings of a product and goes straight to the mid-upper level. I already have JBL sound bars and home audio equipment that's magnificent so the choice was easy to go there for this type of outdoor party speaker. For the refurb/"renewed" price (& I added a 3yr warranty for cheap) it was a no brainer. I was already planning to buy it at full price but couldn't find one anywhere for quite a while, due to the chip shortage I assume.What We Use It ForMy son 11yo plays Select baseball and most teams have a big speaker for warmups/music between innings/walkup songs etc. Some speakers I've seen can get fairly loud but with distortion, lack of bass and clarity. This speaker is muuch different. In the first weekend of use (5 games) four people came up to get a look at the 310 after hearing it from afar and talk about it. I believe I sold two of these already. This thing gets LOUD and people around cannot help but get excited. Even at mid volume everyone in proximity can feel the thump. I never turned it up past 80% and not sure I will ever need to. We ended up going undefeated/winning the tournament and one of the coaches attributed the hype factor of the speaker in keeping the boys energy level up for two days in the extreme heat. After all that the battery level was still at 76%! It's next appearance will be tomorrow at a big pool party we're going to. They recently heard the 310 speaker and asked us to bring it.Best FeaturesThe "rolling suitcase" mobility. The two handles on the box make its hefty weight manageable for loading in/out of vehicles etc. The water resistance. The general sound presence. The deep lows, great midrange and clear treble. The app that allows you to customize everything further. The quality materials. The high end design. The feel of the cabinet and buttons. The customizable light show is amazing. My wife prefers it off but the kids and I love it.Worst FeaturesI haven't come across any yet. It's of course heavy but big sound is going to be. Some people may want a standalone remote but the iOS app fills that need for me and I don't want another remote to deal with.ConclusionIf you're on the fence, take the plunge. I did fairly extensive research and knew this speaker was very solid but it definitely WOWed me and continues to do so. I knew JBL stuff always had great bass and sound quality but was not prepared for the thunder this thing can emanate. I will continue to buy JBL products.
