JBL - PartyBox 310 Portable Party Speaker - Black

I’ve been using the JBL PartyBox 310 for a while now, and it has exceeded my expectations. The first thing that stands out is the sound quality. The bass is deep and powerful without overpowering the vocals, while the highs remain crisp and clear even at high volumes. Whether I’m listening to hip-hop, EDM, reggae, pop, or acoustic music, the speaker delivers balanced, room-filling audio. One of my favorite features is how loud it gets without noticeable distortion. It easily fills a large backyard, garage, or living room, making it perfect for family gatherings, barbecues, birthdays, and outdoor events. The built-in light show adds a fun atmosphere, especially at night, and can be adjusted or turned off depending on the occasion. Battery life has been excellent for my needs, lasting through extended listening sessions without constantly needing to recharge. The built-in wheels and telescoping handle make it surprisingly easy to transport despite its size, which is a huge advantage if you frequently move it between locations. Bluetooth pairing is quick and reliable, and I appreciate the additional connectivity options, including microphone and guitar inputs for karaoke or live performances. The JBL PartyBox app is easy to use and allows convenient control of settings and lighting effects. The build quality feels solid and durable, and the splash-resistant design provides added confidence when using it outdoors near the pool or during unpredictable weather. While it’s not lightweight, that’s understandable considering the impressive sound output and battery capacity. If I had one minor criticism, it would be that the speaker is larger than many portable Bluetooth speakers, but that’s the trade-off for its exceptional performance and powerful sound. Overall, the JBL PartyBox 310 delivers outstanding audio quality, impressive bass, excellent battery life, useful features, and durable construction. If you’re looking for a portable party speaker that consistently provides powerful, high-quality sound for both indoor and outdoor use, I highly recommend it. It’s been an excellent purchase and continues to impress every time I use it.

I bought my first 310 when it was released at the end of October 2020. It was everything I was looking for in a portable speaker. I wanted something with good sound quality and decent bass. This speaker exceeded my expectations! The sound quality is excellent and there's more bass than I expected. I use it a lot in my work van since the factory radio is awful, you can really feel the bass in the cab. I've also taken it to a couple of jobsites (I'm in construction), but only ones I know the speaker is pretty safe from getting damaged. But I have received a lot of compliments on how good the speaker sounds. I have had multiple people ask the price, and hesitate about it, but then as I show them the light show, the app, the pullout handle, the wheels, and of course they're hearing the sound quality, they say they're probably going to buy one. Most of the time, when you bring a speaker to a jobsite, people just go with it and listen to whatever as background noise, but with this speaker, everyone always has to come check it out. This speaker is so good, I had to hear it paired together with another so I bought a second one. Two of them together sound great with the same sound signature, but now with an expanded stereo field. And everything is very easy to do in the app. I turn on the speakers and the one pairs with my phone right away, I go to the Partybox app, click on TWS, the second speakers shows up so I click on that, and stereo. You can switch to just party mode, where they both play as two mono speakers. If you push on either speaker icon it'll light up so you can see which one is the Left or Right channel. There are two levels of Bass Boost. It sounds like Bass Boost 1 is for more lower bass, and Bass Boost 2 is more mid bass. I keep mine locked on Bass Boost 1 as I like the lower frequency bass better. Anyway, the Partybox 310 is an awesome speaker. If you're on the fence, just get it, you'll be happy. Pros: portable, long battery life, great sound quality, pull out handle and wheels, splashproof rated, pairs easily to another same model JBL, very easy to use companion app Cons: I have nothing bad to say about this speaker

To give some background I had been looking for a large more powerful Bluetooth Speaker as I already own several small Bluetooth speakers as well as the JBL Pulse 3. And I learned that between my JBL pulse and other branded Bluetooth speakers that the JBL has a extremely noticeable difference in audio quality! I researched and compared the JBL PartyBox On The Go, Boombox 100, 300 and 310. I finally decided on the 310 because it had a handle and wheels making it easier to move around the house (in doors or outdoors and Garage) plus unlike the others it had an IPX4 water resistant rating and as I live in Florida sudden rain showers and splashes around our swimming pool could be an issue and I didn’t want to panic if it got splashed or rained on suddenly! The IPX4 gives me peace of mind that it can take a little water and give me time to get it out of the rain. I also chose the 310 over the 100 as it has a much larger internal battery than the 100 and the 310 can run on Battery, AC and DC Power while the 100 only runs off it’s battery so if the battery stops working you can’t use the speaker. I have played the 310 on battery for between 4-7hrs and still had quite a bit of charge left on the battery (Speaker volume between 40-70% and level 1 Bass Boost and no light show). I chose the 310 over the 300 as the 310 is IPX4, has a handle and wheels and the interactive JBL PartyBox App for my iPhone XR! The sound on this 310 is simply amazing it is so clear and the Bass is amazing! In MHO it’s worth spending a bit more to get the added features over the partybox 100 and 300. Plus spend the extra $$$ to get the JBL sound performance so you won’t have any regrets later! I used this speaker allot over the Holidays and wether playing Christmas Music or Jamming our for New Years Eve this Speaker does not disappoint and has amazing sound and really shakes the house!! I highly recommend this Speaker and our Family Loves it......it’s exactly what I was looking for!!

This speaker is an absolute game changer. The sound quality is powerful, clear, and the bass hits hard without sounding muddy. It easily fills up any space, whether it’s indoors or outside, and still sounds great even when you turn it up loud. The light show is one of my favorite features—it syncs perfectly with the music and really adds to the vibe. It makes every get-together feel like a real party. The battery life is also solid, lasting up to around 18 hours, so you don’t have to worry about charging it constantly. I also like how easy it is to move around thanks to the wheels and handle. It’s definitely not small, but it’s very portable for how powerful it is. The mic and guitar inputs are a nice bonus too if you want to switch things up with karaoke.

I was in the market for a Big/Party Speaker recently and I did a lot of research I heard saw Sony speakers, LG, Bose and JBL and I went with this JBL speaker over the 110 Party box. I heard great things about this speaker and was honestly very hesitant. I am very picky about my speakers/sound and while I trust JBL with their smaller speakers, I didn’t know if I’d enjoy the big ones. Well I’m happy to say I am thoroughly impressed! The sound in the Party Box 310 is amazing, clear and it gets very loud! I am someone who listens to many types of music genres so the in-app equalizer being simple is very helpful! Sometimes I love being a Bass Head and the Bass on the JBL does not disappoint whatsoever! The battery life of 18 hours is insane because I have yet to kill the battery in one use! The portability is also amazing! The handle feels sturdy and it’s not so overbearingly heavy that I couldn’t pick it up which makes the addition of the grab handles on the speaker a nice touch.

Very pleased with the sound BUT super disappointed on the battery life - 5 hours tops on a full charge - no lights going for any extra drain - also a pretty significant power / wattage loss from when it is plugged in, to playing on a battery charge. If it even was able to play 8 hours I would have scored it a 5 - but my beach party / Jimmy Buffet day suffered a terrible ending thinking I had at least 10 hours at the beach -

I have received apparently a used product and apparently I had to open after a week to my notice that it was used and already broken and painted at different parts of the speaker. Highly disappointed and going back to Best Buy to return the product and hopefully get back my refund.
