Jbl Partybox 300 Watts Portable Bluetooth Party Speaker With Bass Boost And Dynamic Light Show (240 Watts, Black)
We have mentioned earlier in our article of ‘JBL Xtreme Portable Wireless Bluetooth Speaker’ and ‘JBL Charge 2+ Splashproof Portable Bluetooth Speaker’ that, JBL electronic products manufactured by Harman Corporate is an American Company, but SAMSUNG bought the Company.

JBL PartyBox 300 is their cool and unique Bluetooth speaker is designed for parties. It’s something that is quite suggestive of something that Sony already has. It is a huge speaker that dancing its own light shows while blasting out all your favorite tunes and beats. It’s definitely something that would make your party one of the best, hottest, and successful.
The reason why you need to choose this portable Bluetooth speaker
Design of the speaker:
This party speaker measuring 27.1 by 12.2 by 12.6 inches (HWD) and weighing in at an awkward 35 pounds, though the PartyBox 300 has built-in handles, rubberized feet on two side panels and the bottom panel as well. So, it can be placed vertically or horizontally easily. We suggest operating when the party box at a vertical position due to control panel houses on the top when it is laid vertically. At the laid position on its side, the controls are on the top and easy access, you just have to bend down to use them. The front side is covered by grills and under the grills; there are two 6.5″ woofers, three 2.25″ tweeters. These deliver massive sound with remarkable bass response.
Portable to carry outside
When you see this JBL party box, it is hard to believe that this sound machine is portable, but it is. Not only that, in the sense that it can be moved around easily, and it can operate off of its internal battery. This party rock speaker has a large size Lithium-ion 74.88Wh battery that can play music for up to 18 hours—though this will mainly depend on your volume levels. So, if you’re blasting it and using the LEDs, expect lower numbers. The negative side is that the battery takes five hours to fully charge which is a little bit disgusting.
Get rock in the party
You will find the all connections panel on the backside of the speaker where placed input for RCA, 3.5mm aux, and USB connections, as well as the dedicated mic and guitar inputs, which each have their own gain knobs also directly on above them. Both mic and guitar inputs are a quarter-inch, so if you’re trying for using an XLR mic, you just need to buy an adapter. The party rock speaker’s connection section there’s also an RCA output and a left/right channel button for pairing up two of these speakers and powering what could become your ouster party.
Up top of the JBL 300, there’s a control panel with buttons for power, play/pause, Bluetooth pairing, bass boost, and volume. You will find also a button there that activates or disables the LED light show.
Use XLR mic input
The PartyBox 300 comes with only two accessories: a regular-sized power cable of usual length for a large speaker, and a heavy-duty orange color car charger cable that is quite long. Other than perhaps some audio cables, what’s missing? If designers could put wheels at any one of two sides of the speaker, it would be easier to removable or retractable, so it’s understandable why they weren’t included. There is an XLR mic input would also be nice, so that higher-quality mics can be used.
JBL PartyBox 300 Inputs, Outputs & Control that have easy control
The JBL PartyBox 300 has one thing that most party speakers don’t is quarter (¼) inch inputs. There is one for a microphone and one for an instrument such as a guitar. Each quarter (¼) inch input has its own committed volume control so that, you can adjust the volume levels to get the perfect mix.
Other inputs are including a ⅛-inch AUX, USB, stereo RCA, and Bluetooth. There is also a stereo RCA output which could be used to link with another speaker or record your live show or karaoke session.
The USB port also doubles as a power bank for charging mobile devices and playback too. Again, this charging mobile device will have an effect on battery life.
On top of the PartyBox 300, there is housing a control section where you’ll find several buttons to control the speaker and music. These include a power on/off, play/pause, Bass Boost, Bluetooth pairing, lighting effects toggle, and volume control. At the back of the speaker, on the input panel section, you have an L/R button for switching the PartyBox 300 between stereo or mono when paired with another PartyBox 300.

What you will get within the Box?
When we received the PartyBox 300 on our hands, it came in a strong and durable cardboard protection box that is to protect the speaker from any shipping damages.
We found the front of the box displays a printed image of the speakers, the speaker model, and the company’s name. Below the image is a tagline that states “Powerful Bass Boost”, and a couple more details about the PartyBox 300.
There is also mentioned on the box that the speaker is Bluetooth compatible and the other details and information about the speaker plus some other features of the speaker.
When you open the box, the first thing you’ll find is the speaker itself that is covered with a white plastic wrap to protect it while being transported to your home. Aside from the speaker, the package also comes with an orange color 12-Volt DC cable, an AC power code (that varies by the region), a safety sheet, a warranty card, and the quick-start guide.
Performance of this JBL portable speaker
Underneath the large metallic grille panel, the PartyBox 300 has dual 6.5-inch woofers and dual 2.3-inch tweeters delivering a sound frequency range of 45Hz to 20kHz and a whopping and weighty 100-120 watts RMS. Let’s describe volume for a second. The volume levels work in conjunction with your paired mobile device’s master volume together, like most Bluetooth speakers.
However, unlike most Bluetooth speakers, probably a reasonable everyday listening level for the JBL PartyBox 300 is around 25 percent, but if you really want to rock-out music, 40 percent is enough. That means the speaker has the ability to get PA-system incredibly loud, and you’d be better be prepared for it—our advice is to start off with your volume level at zero and raise it from there.
Bass boost delivers
On tracks with acute sub-bass content, it seems “The Knife’s Silent Shout,” even with the bass boost disabled, the PartyBox 300 able to delivers some serious low-end. Turn on the bass boost; you’ll feel the things really roaring. At testing time, we have played it at full volume like this for perhaps thirty seconds, we just realized, impressively the drivers do not distort on this challenging track which we did not expect. At medium levels, like 45 percent, the speaker is still abundant loud, and there’s a lot of bass depth response in all modes.
We track with Bill Callahan’s “Drover,” far less deep bass in the mix, and it gives us a better feeling of the PartyBox 300’s normal sound signature. The drums on this track still sound thunderous with the bass boost off, and Callahan’s baritone vocals get an extremely rich presence. There’s also on a large scale of high- mid and high-frequency creatively to balance things out, but this is not a perfect sound signature. This is for a party sound signature, big on low-end and super-crisp highs. Together with the bass boost, especially to the highest level, takes tracks like this to a ludicrous place—the drum’s roaring almost overtakes the entire mix.
No Church in the Wild
The kicks drum loop receives an ideal high-mid appearance on Jay-Z and Kanye West’s “No Church in the Wild”. It is allowing its punchy attack to stay its edge. The beat is delivering with serious power when the sub-bass synth hits with punctuate. But the bass boost mode seems to push the thump of the drum loop leading more so than the sub-bass synth hits. Regardless of what dominion of bass is getting boosted here. This is a deeply bass-heavy sound signature. The vocals come through clearly when the bass boost off, though there’s some notably added sibilance coating them.
Play as a music amp
The PartyBox 300 would be more appropriate when it is using with an amp. An example, an electronic synth than an electric guitar. Apparently, you won’t be getting any of the benefits of tube-amp tone through this system, it’s just a loudspeaker. The PartyBox karaoke speaker, it works fine. But much of that will depend upon the microphone you use. It also depends on setting the right levels on the back panel. Different singers will likely need different gain settings in karaoke mode. It’s pointedly wise to have someone near the speaker back panel who can manage the mic gain on as needed.
Better display status
The LED light shows are fun and cheer up the party, and probably are great in a party scenario. Tapping the button on the top panel lights up LED strips that encircle the drivers. There are mini strobe-like lights that flash on and off, and you can cycle with various modes that deliver several colorful patterns as well. The LED light flash, blinks, and sometimes gives the impression to follow the rhythm of the music. To turns the lights off, you need to press the button enough times.
When it is a reason for the speaker’s performance, the JBL PartyBox 300 is simply wonderful. Even the speaker’s bass boost is not set up, the music already that comes out sounds clean and great. But when you add on the bass boost, you’ll surely have a blasting and booming sound party all throughout. JBL PartyBox 300 isn’t just only all about listening but also matter of every instrument’s learn sound come out.
Play guitar riffs
Now if you plan to take your favorite tunes to the next level you can pair another PartyBox. It is really a great and very smart option. The mutual speakers can easily go to pairs to amplify. You can boost any music to audio when the party is running. If there is a person in the party who can play the guitar and bass can use JBL speaker. It comes with a guitar jack, you can completely use it to rock out with the best guitar riffs. Not only that but also have an option to add the microphone jack to it. You with your friend can perform for a party or any crowd as extra fun.
Even when the party is outside, and it comes to two pairs of speakers together, sounds would be so loud. The party’s playlist consists of a variety of streams. Playing all music sounds would be great with 250 Watts of pure volume. And it is especially the deep bass notes that give more power to the tunes.
Integrated lighting effects
You’ll really love how the PartyBox 300 looked when the integrated lighting effects came up. The lights flashed in time with every single beat and it really added to the party atmosphere. Another thing that, you’ll like about PartyBox 300 as a power-bank. When a smartphone’s battery is dying out, you just plugged it into the speaker’s USB port and quite surprisingly. The music still goes to continue to play while the phone is charging without any problems.
