JBL PartyBox 100 vs JBL PartyBox 300 (2021): Choosing Party Speakers

Whether it’s a house party, a pool party, or a beach party you’re throwing, the best way to liven things up is with music. That means high-quality party speakers are a necessity, ones that will deliver powerful sound output, create the perfect atmosphere, and last longer than everyone else in the crowd. The JBL PartyBox line was specifically designed to meet these party needs, giving us two party speakers that are sure to bring the house down: the JBL PartyBox 100 and the JBL PartyBox 300. The former is a more compact unit that might be the better choice if you’re after portability. The latter, on the other hand, is much heavier but is a great option if you want power and longevity. To help you decide, let’s take a closer look at these two models.

The JBL PartyBox 100 is a much lighter unit than the JBL PartyBox 300 and comes with a pole mount.

Both the JBL PartyBox 100 and JBL PartyBox 300 have the same rugged, heavy-duty design but you can easily tell them apart by their size and weight. The JBL PartyBox 100, weighing in at 9.7kg, is the smaller of the two and is the definite winner when it comes to  portability. It might be the better option for destination parties as you obviously don’t want the hassle of having to lug around a heavy piece of equipment.  The JBL PartyBox 300, heavier by a whopping 6kg, requires quite a bit more muscle power if you want to bring it along to the beach. It does come with carrying handles, however, making it a little bit easier to move around.

Another point against the JBL PartyBox 300 is its lack of a pole mount, a feature that its smaller counterpart boasts of. You can prop the JBL PartyBox 100 on a post so that it can be better seen and heard by the party crowd. After all, why invest in a party speaker if you can’t show it off? The pole mount also allows you to use your speaker as a PA system if your event calls for one, making it the more versatile model of the two. As for the JBL PartyBox 300, you’re left with two options: to place it on its bottom or have it to its side.

Portability and versatility aside, both the 100 and 300 models are able to bring the fun to the party through their light show feature. You can choose from several RGB LED patterns or you can let the lights dance freely to the beat of the music. Regardless of which model you get, your party guests are sure to get an audio-visual treat. You can always shut the lights off if you want more of a serene environment.

Sound Performance

The JBL PartyBox 300 delivers a more powerful performance than the JBL PartyBox 100.

Both the JBL PartyBox 100 and 300 models have a Bass Boost button for more power.

The JBL PartyBox 300 may be bulkier and harder to bring around but it’s a small price to pay if it’s power you’re looking for. Able to pump out 240 Watts of JBL’s signature punchy, bass-heavy, and immersive sound, it’ll bring the crowd to life as soon as you turn the music on. If you’re trying to fill up a bigger space, it could prove to be the better option. The JBL PartyBox 100, being the smaller of the two, performs at a lower power of 160 Watts and is more suitable for smaller, enclosed venues. The difference between the two in terms of power is a pretty big one and so it’s definitely something to take into consideration when finding the perfect party speaker for your needs.

Another reason why the JBL PartyBox 300 boasts of a more powerful sound is because it has more loudspeakers. It has two 6.5-inch woofers and three 2.25-inch tweeters while the JBL PartyBox 100 only has two 5.25-inch woofers and two 2.25-inch tweeters. Both models do, however, come with a Bass Boost button which you can use to crank the bass up a notch or two if needed. You can also reduce the bass if you find that it’s a little too much.

An interesting thing to note about these two speakers is that they are both much louder than your average speakers. You can have your volume at only 40% and that will be enough to catch everyone’s attention. If you’re using them for normal listening purposes, it’s best to have your volume low at around 25%.


The JBL PartyBox 100 and JBL PartyBox 300 have the same connectivity features. 

Both the JBL PartyBox 100 and 300 come with various input and output options.

When it comes to connectivity, both the JBL PartyBox 100 and JBL PartyBox 300 are at par with each other. They’re both versatile options in this aspect because you can pretty much connect them to anything. If it’s a karaoke session you’re after, they both have microphone inputs, allowing your guests to belt out as many tunes as they want to. If you want to have a jamming session, these models also have guitar inputs, allowing you to rock for hours. If you want everyone to hear the playlist on your phone, both are Bluetooth-enabled. If your songs are in a USB, you can play those too because they’re equipped with a USB port. You can even connect an additional speaker to them if you want more power because they have RCA outputs as well as True Wireless Stereo (TWS) modes.


The JBL PartyBox 300 trumps the JBL PartyBox 100 in terms of battery life.

The JBL PartyBox 300 can last up to 18 hours of playback time.

Aside from size and power, another significant difference between these two party speakers is battery life. If your parties rage on until the wee hours of the morning, you might want to consider getting the JBL PartyBox 300 because it promises 18 hours of playback time and so its energy is sure to outlast that of your guests. As for the JBL PartyBox 100, it only takes 12 hours for its battery to completely run out of juice. Do expect less hours for both models, however, if you’re playing your music on full blast and have the lights on the whole time. Of course, you can always use the AC adapter and connect it to any available electric outlet if you don’t want to worry about the music going out during your party.


The JBL PartyBox 100 wins in portability but the JBL PartyBox 300 dominates in power.

Both the JBL PartyBox 100 and JBL PartyBox 300 live up to the definition of party speakers. They both definitely outperform the run-of-the mill desk speaker, both delivering impressive and powerful sounds that can amp up any party. They get plus points as well in the connectivity area, both featuring a wide variety of input and output options. There are some important differences, however, that buyers need to take note of when deciding between these two models.

If portability is a huge factor for you, the JBL PartyBox 100 is the way to go. It has the same durable design but is much more compact, making it a lot easier to carry. The much heavier JBL PartyBox 300 is much more suited as a permanent fixture that doesn’t need to be moved around. If the JBL PartyBox 100 is perfect to bring along to beach and pool parties, then the JBL PartyBox 300 is perfect for house parties.

If power is what you’re looking for and don’t care so much for portability, the JBL PartyBox 300 is the better investment for you. Its ability to deliver 240 Watts of power, as compared to the JBL PartyBox 100‘s 160 Watts, can’t be overlooked. Its battery life is much longer as well, making it the more dependable party speaker.
