The JBL PartyBox Stage 320 is a portable speaker that lets you wheel in a party-ready sound system for any occasion. It comes equipped with the familiar RGB lighting framing its drivers, dedicated mic and guitar inputs, and an IPX4 rating that makes it (mostly) party foolproof. Plus, its purported 18 hours of battery life and swappable battery pack design should have you partying through the day and into the night. There are options to connect to older PartyBox speakers and other Auracast-compatible speakers, too, which will be a welcome bonus for users who already own a JBL speaker.
Our Verdict
The JBL PartyBox Stage 320 is very good for music. It features a balanced sound with ample low-end on tap, which can help the kick drums and basslines of electronic music really shine. It has a balanced mid-range, too, which ensures vocals and lead instruments sound clear and detailed. Plus, you can always tune the sound to your liking via the graphic EQ and presets. While it can't get as loud as some of its larger PartyBox siblings, it's still loud enough to fill larger rooms with sound. There will be some compression in the bass range as you crank the beats, though. Its dual tweeter configuration means it's capable of playing back stereo content. Just be mindful that its front-facing design doesn't allow for the best directivity.

The JBL PartyBox Stage 320 is okay for videos and movies. Its default frequency response has plenty of low-end to inject excitement into action sequences and energetic soundtracks, and the balanced mid-range ensures that dialogue comes through clearly. It also gets plenty loud to soundtrack larger watch parties, though you'll want to switch off the potentially distracting RGB lights. Despite its capability of playing back stereo content, with some separation between left and right channels, its directivity isn't the best, so you'll need to ensure your audience is seated in line with the drivers to facilitate consistent audio reproduction. While latency with iOS and Android devices isn't the lowest, it should still make for a relatively lag-free experience. Different apps and devices compensate for latency differently, though.

The JBL PartyBox Stage 320 is good for podcasts. It's capable of rendering mid-range content, like your favorite podcast host's voice, in a detailed and clear way. Plus, it can get loud enough that audio won't get lost if you turn a fan on as you cook with a podcast on. That said, its directivity isn't the best, so audio sounds clearer from some angles over others. While you can always retract its carrying handle and wheel it to another room, you'll want to leave its bulky frame parked in one place wherever possible.

The JBL PartyBox Stage 320 doesn't have a mic or any integrated features that allow it to be used with a voice assistant.
The JBL PartyBox Stage 320 is very good for outdoor use. It's decently well-built and will survive spilled drinks and light showers alike, thanks to its IPX4 rating. Just don't dunk it in a pool and expect its heavy frame to float (or for it to still work). Its 23 hours of battery life means it can soundtrack even the longest dance parties, and it has the volume to project in outdoor settings, too. There will be some compression in the bass range, though, and its middling directivity means that not every partygoer will experience consistent audio reproduction.

Differences Between Sizes And Variants
The JBL PartyBox Stage 320 comes in two color variants: 'Black' and 'White,' and here's a picture of its label. If you encounter another variant of this speaker, let us know in the comments, and we'll update our review.
Compared To Other Speakers
The JBL PartyBox Stage 320 is positioned in the middle of JBL's popular PartyBox line of portable speakers, both in terms of price and power. While it's not quite as portable as the JBL PartyBox On-The-Go (which is light enough to be carried around with a shoulder strap), it boasts the same ground-shaking volume outputted by the JBL PartyBox 710 (without the considerable heft). Users who want a speaker with even more bass on tap can check out the Sony ULT FIELD 7, which has two additional levels of 'ULT' bass. It also comes with an IP67 rating, making it a more durable choice than the mostly IPX4-rated PartyBox line.
If you're looking for more options, check out the best Bluetooth speakers for bass, the best JBL speakers, and the best Bluetooth speakers.
There's not much to differentiate between the JBL PartyBox Stage 320 and the JBL PartyBox 310. Both are large, bulky speakers that rely on their wheels and carry handle for portability. They're also both equipped with RGB light shows, mic and guitar inputs and stereo playback capabilities. The main difference is in bass and dynamics performance. The PartyBox 310 produces more punch by default, and also compresses a bit less at high volumes. There are some slight differences when it comes to frequency response, too. The Stage 320 features a more balanced response overall, compared to the 310's warmer, boomier sound, which some may like but others may find dull.
The JBL PartyBox Club 120 is a solid, more portable alternative to the JBL PartyBox Stage 320. Despite their differences in size and weight, they perform very similarly when it comes to frequency response and dynamics, and they're capable of achieving similar levels of bass. The Stage 320 is capable of getting louder though. Both speakers have a similar build quality, with IPX4 ratings, and they even both feature mic/guitar inputs for added karaoke/busking functionality. The key differences are in directivity, where the Club 120 offers more consistent audio reproduction from different angles, and battery life, where the Stage 320 offers 13 hours more juice per charge.
The JBL PartyBox Stage 320 and the Ultimate Ears HYPERBOOM are both solid options for parties, with slightly different strengths. The Ultimate Ears is quite a bit more portable, and its design allows for better directivity. It has much lower latency with iOS and Android devices, too, and though it can't reach the same top volume as the JBL, it compresses considerably less. That said, the JBL has a more balanced default frequency response and comes with guitar and mic inputs for extra karaoke fun.
The Sony ULT FIELD 7 offers some key advantages over the JBL PartyBox Stage 320 when it comes to build quality and frequency response. The Sony's IP67 rating makes it a more durable, all-weather alternative to the JBL, and its switchable levels of bass via the 'ULT' button ensure there's plenty of low-end oomph available to call upon. It's also quite a bit more portable and can be carried around over your shoulder using its carrying strap. That said, the JBL boasts a much longer battery life, less compression at max volume (though both speakers have similar max volumes), and slightly better directivity.
The JBL PartyBox Stage 320 is a better speaker than the ION Tailgater Tough. It has a more balanced frequency response overall with greater extension in both the bass and treble ranges, so it's better suited for listening to a variety of music genres. The JBL also has a better soundstage with less directivity, so music sounds more consistent from various angles, and it can play audio in stereo without downmixing to mono, unlike the ION. It can get louder, too, albeit with some loss of clarity as you crank up the volume. The ION, on the other hand, is more portable, even when considering the JBL's wheels and collapsible handle.
Test Results
The JBL PartyBox Stage 320 looks pretty similar to many of the other speakers in JBL's PartyBox line, with the same LED ring lights on the drivers and a collapsible handle to more easily transport its wheeled frame. Unlike the JBL PartyBox 310, this version can only be placed vertically. It comes in 'Black' and 'White' variants.
This speaker isn't very portable. While it comes with wheels and a collapsible carrying handle, its heavy and bulky frame means that it's still not a great portable option. While it can technically be carried in one hand, it requires a great deal of strength to do so.
This speaker has a decent build quality. Its frame is made of tough, durable plastic, with a metal grille covering the drivers at the front. A small groove on the top panel can act as a phone holder, though we don't recommend putting anything here as you can easily break your device by applying force in the wrong direction. The speaker is rated IPX4, meaning it's protected against splashes of water, and there are sealable covers for the various inputs to help keep stray substances out. You'll find rubber feet on the bottom to help with stability, as well as built-in wheels that can help you cart it away. Additionally, there's a removable cover on the bottom of the speaker that can be used to mount the speaker to a stand for better projection.
This speaker's control scheme is great, meaning there's not much of a learning curve when it comes to using it. Most of the controls are located on the top panel, with additional controls for input gain found next to their respective inputs on the back panel. All the buttons on the top panel are clicky and easy to press, with secondary functions that correspond well to their primary functions. There's visual feedback from LEDs that indicate when Bluetooth pairing is in progress, as well as visual indicators for volume level, battery life, and Bass Boost status.

The JBL PartyBox Stage 320 has a great default frequency response accuracy. With the Bass Boost set to 'Deep' and with the 'JBL Signature EQ,' it produces a balanced sound, with plenty of rumble in the low-end that accentuates the basslines and kicks in electronic music. The mid-range is more balanced than the JBL PartyBox 310, too, resulting in vocals and lead instruments that have plenty of clarity, even in dense mixes. There's a bit of underemphasis in the treble range, though, which can take some of the airiness away from breathy vocals.
This speaker also comes with an 'AI Sound Boost' feature that the manufacturer claims analyzes the incoming audio signal in real-time using an AI algorithm to predict how this will affect the drivers. We subjectively found that this feature improved the tightness of the bass range.
The soundstage performance is decent. This speaker's driver configuration means that it has a pair of stereo tweeters and two mono subwoofers. Given most sound reproduction stems from the large tweeters, it's able to playback stereo content without downmixing to mono. Its directivity isn't the best though, so audio won't sound consistent across every listening angle around the speaker.
The JBL PartyBox Stage 320 has a great dynamics performance. It can get loud enough to fill a larger-sized room with sound, though there is some compression in the bass range as you crank the volume up.
This speaker has an incredible battery performance, especially considering its size. The manufacturer advertises up to 18 hours of playtime, but we were able to achieve over 23 hours during testing. As this speaker features a swappable battery pack, you can even purchase another JBL Battery 400 to double the battery life easily. There's also a power conservation feature that switches the speaker to standby mode after 20 minutes without audio input.
The JBL PartyBox app gives you lots of control over basic and more advanced parameters, as you can see from our app video. You can alter the sound via a graphic EQ and presets, adjust the RGB lights, or change any of the top panel controls without having to be physically near the speaker. You can also initiate True Wireless Stereo Pairing or Party mode with another compatible speaker and adjust the effects on the mic input. There are even some novelty DJ effects (mostly sound effects like airhorns and vinyl scratches) available via the Effect Lab. This PartyBox iteration also allows you to connect to older PartyBox speakers or other AuraCast-compatible JBL speakers.
This speaker has a few different wired inputs available for various uses. There's a standard AUX in/out for connecting or chaining devices via an analog connection. There's also a mic input and a guitar input, each with its own dedicated physical gain controls.
The JBL PartyBox Stage 320 has great Bluetooth connectivity. Support for multi-device pairing is included, so you can pair up to two devices. Latency with both Android and iOS devices falls within good limits, too, so you won't experience much in the way of lag between your audio and video if you use the speaker to soundtrack a movie. Different apps and devices compensate for latency differently, though. That said, there's only support for the SBC codec, with no option to connect via high-resolution codecs like LDAC.

JBL PartyBox Stage 320: Main Discussion
Let us know why you want us to review the product here, or encourage others to vote for this product.

Ok thank you. Exactly what I needed to know. And wanted to mention, after inquiring about the issue, I found out the motion bug was introduced in firmware 1410. A fix was later attempted by Samsung in firmware 2011, but did not resolve the issue. Could be why you guys didn’t experience the problem when testing.
I watch everything in game mode due to bad audio sync with my denon receiver. I don’t notice any awful banding or upscaling issues. Of course, I’m not as rigorous in my testing compared to rtings lol
- 21010
Thanks. But what about the viewing angles and colour shift?
The videos rtings posted regarding the viewing angles is pretty accurate. I don’t have the monitor super close to my face like some people like. It’s about 1.5ft - 2ft away from me and I don’t notice any issues.
I used to game on my VA Samsung tvs and the smearing was AWFUL on those. So I’d consider myself moderately sensitive to smearing.
However, I’m red-green color blind and color shift isn’t noticeable to me. Changes in brightness due to viewing angles are noticeable to me and I don’t see this in my usage with this monitor.
- 21010
I have never seen a monitor with VA panel in person, so I have no idea what black smearing looks like. Do you think it would be very noticeable on this particular one when playing shooter type of games? It’s not the kind of game I play often, but is one of the main reasons why I am looking for 60Hz+ monitor. Other than that, do you think this monitor would be good enough for colour-critical work? I do photography as hobby and work in Adobe Lightroom relatively often, even if only as a hobby. I am looking for decent panel uniformity. As long as it’s calibratable in sRGB mode I guess I am fine, but like I said, I have zero experience with VA panels so I haev no idea how they fare in this category.
I have this monitor, and I don’t notice any smearing during gameplay. I’m sure it’s there - but I’m thinking you really have to look for it. Set overdrive to medium and don’t break out the magnifying glass.

Are there any budget oled options yet?

Anyone with S90C 83" with WOLED panel, experienced any burn in while playing games ?
I’ve been playing a games on this tv since we got it November last year, and I haven’t noticed any burn in. I use a pc, with the taskbar set to “auto-hide” and I avoid games with egregious static elements (like Stardew Valley). I keep those strictly on my TN monitor.
I am playing through horizon zero dawn which has a rather prominently colored static health bar and I haven’t noticed any burn in.
- 21010
I wouldn’t because of material quality, mine cracked in a few months and had to use epoxy to fix them somewhat. I don’t have a big head, they are good for traveling and they sound good specially if you bother to eq them, i had issues with the mic due to people finding it very screechy on discord but fixed it with the mic noise settings… I liked them… But they just cracked so fast. Also… If you do get them be careful with updating them, my first pair bricked but had Amazon replace them… From time to time when my zen hybrid pro die I’ll use them for a bit but am always wary when I put them on cause of the cracks, same with my old barracuda x
Thanks for the heads up. I grabbed the EPOS H3pro on clearance at Best Buy for $112.99. So far so good. It checked all the boxes and comes with a detachable boom mic instead of tinny integrated mics. I have no rtings.com review to compare it to but they sound great to me. Lots of reviews complaining about connectivity issues but I haven’t had issues so far.

VESA is beholden to these companies. If the certifications are too hard to obtain, they will not succeed as a business.
- 21010
Yes I’m indeed gonna use it as PC monitor
I use this as a PC monitor and I have some ideas based on my experience. Set the taskbar to automatically hide. Also don’t use desktop icons (or in my case, put them on your second monitor that is not an OLED screen). I use this TV as my main screen so I can launch the games to it, but I do all the typical computer stuff on my second TN panel monitor.

Does the ANC work while using the wired connection? The Q30s I bought have the ANC disabled over a wired connection.

I have this issue with internal apps and external devices. The varying degree of delay is what makes this frustrating to solve. No one setting fits all sources.
An eARC receiver did not solve my issue. Audio is randomly out of sync. It’s different every time you start watching something. Sometimes it’s even behind and unfixable. Samsung is criminal.

I’ve been having difficulty getting audio to sync on this tv. I had zero issues on my q90r. I’m currently using ARC, but I have purchased an eARC receiver to see if it resolves the issue. It does occur over the TV speakers as well. The delay changes depending on the app, anywhere from 40ms with YouTube to 450ms using ANY 4kHDR content. When connecting my PC, the audio is actually BEHIND the video. Which is impossible to fix using tv/avr settings
Has anyone else experience this? I do have the 83” version, but I imagine the audio settings are virtually the same.

Here’s a picture of the sub-pixel layout on the 83 inch variation for those curious.

Yes. It’s at 4k, but the only option I see is for 120hz

Unpopular opinion: non-intrusive banner ads.
As long as ads don’t take over my screen or load mid-way through scrolling the site, they don’t bother me. I’d prefer a banner ad at the top of my screen as opposed to a paywall. Just my two-cents.
- 21010
I’m guessing that you may have VRR/Freesync/Gsync enabled on your console or PC. You’ll see a huge improvement in quality if you disable this. Hopefully Samsung will fix VRR mode soon as it looks quite bad right now (elevated and crushed blacks and dimmed whites, plus poor color accuracy).
No VRR. I’ve tried to both ways. Tons of troubleshooting on my part. I’m currently using pass through on a receiver for audio quality. But I’ve tried direct tv connection. Only way I don’t get insane blooming is with game mode off. Vincent does a video on this on his YouTube channel for hdtv test.

If I can sway your opinion, please buy a better budget tv. Like the hisense.

The content on this website is superb. You review what people vote on, and give recommendations in finely crafted articles that are frequently updated. Expecting a newly added television to have comparisons immediately is unrealistic.
- 21010
I agree, but I fear this may be impossible to test. OLED has ABL, which is why I’ve resisted OLED so far. And Samsung has nice TVs but the brightness change with subtitles is annoying. I also see random dimming from CE dimming, which I’ve tried to disable via the service menu, but I still see my issue from time to time. Maybe the test could be a simple one like ad-free? All or nothing kind of score?
- 32120
Game mode is awful on Samsung TVs. I’m not sure if there is a solution possible through firmware updates, but for now it’s just awful. I get terrible clouding on my tv. If I turn off game mode, it looks amazing with unacceptable input lag.

LG does not support hdr10+. Those technologies are gimmicks, and they crush blacks and whites by expanding the contrast.

That’s a good question. At the moment, we have a subjective evaluation of the upscaling performance. Upscaling preferences vary between people though as some people prefer a sharper image even if it has artifacts while others prefer a softer image, so only if a TV performs really badly (eg. very blocky) then it gets a lower score. We have looked into an objective test for upscaling, as there are industry metrics like the peak signal to noise ratio (PSNR) to determine how well an upscaled image matches the reference original. This is extremely hard for us to evaluate though, as we can’t obtain a pixel-perfect image of the screen. If you have any ideas for how we can improve it, then please let us know.
It was more out of curiosity. I just feel like upscaling methodology that tv manufacturers use is going to be the next big marketing gimmick because it is hard to verify and compare performance. You folks do an awesome job. Thanks for the response.

Definitely panel issues with Q9fn. Most of these issues are counteracted by local dimming, but it is still noticeable if you know what you’re looking for. And I haven’t experienced issues with sound, but I’m more focused on picture quality myself. My receiver and speaker setup doesn’t even have ARC. I’m still using optical.
