The JBL Boombox 2 has a more compact and lightweight build, thus, it is easier to carry around with one hand. Measuring 19.1 x 7.9 x 10.1 and weighing 13 lbs., it is the more portable speaker. The top handle that’s built into the speaker also contributes to its portability.

The JBL PartyBox 300, on the other hand, is large and heavy. It measures 12.2 x 12.5 x 27.1 inches and it weighs 34.9 lbs., so it is more than double the weight of the JBL Boombox 2. While it is big and heavy, it is still portable. It has a telescopic handle that allows you to move it around. The JBL PartyBox 310, another large party speaker from JBL, has an improved design with wheels that is easier to move around.

When it comes to build quality, both are excellent. These two speakers are made with mostly plastic but they still feel durable. The JBL Boombox 2 has a tight fabric that covers the entire speaker and it has an excellent build quality to it. Meanwhile, the JBL PartyBox 300 has a metal grille that protects the speakers on the front side. One advantage of the JBL Boombox 2 is that it has an IPX7 rating, which means that it is waterproof. It is more suitable for pool parties or gatherings at the beach since it can withstand splashes and it can even be submerged in water.

Features and Controls

The RGB light show of the JBL PartyBox 300 is a nice visual treat during your party.

The JBL PartyBox 300 is a nice speaker to have during parties. In addition to its loud music, it also comes with an RGB lighting feature that will surely add to the atmosphere of your party or gathering. In addition to its RGB light show, the JBL PartyBox 300 also has a built-in karaoke mode and it also has an input for a guitar. You can use it as a karaoke speaker and a guitar amp.

The JBL Boombox 2, in contrast, does not have any kind of RGB lighting effect and it is quite limited with its inputs (more on that later). The main features of the JBL Boombox 2 are its water resistance and its support for JBL PartyBoost. PartyBoost allows you to pair it with other JBL speakers that also have this feature.

Their controls are simple and the buttons are responsive and easy to press. The JBL Boombox 2 has dedicated buttons for power, Bluetooth pairing, volume up/down, play/pause/skip and PartyBoost. Meanwhile, the JBL PartyBox 300 has buttons for power, Bluetooth, RGB, volume up/down, play/pause and Bass Boost.


The JBL PartyBox 300 sounds better than the JBL Boombox 2.

Capable of outputting more power, the JBL PartyBox 300 can get very loud. What’s impressive about it is that at a higher volume, there is very little audio quality degradation. However, at max volume, you will start to notice some. When it comes to loudness, the JBL PartyBox 300 is definitely ahead of the JBL Boombox 2.

As for their sound profiles, the JBL Boombox 2 has a balanced sound that is suitable for all kinds of music. However, its low frequency can be lacking. Unfortunately, it doesn’t have an EQ so you can’t really adjust its sound. The mids and the highs sound clear.

The JBL PartyBox 300 has a fuller and richer sound and its low frequency is also more present. The mids and the highs are slightly recessed, but not to the point that they are lacking. With its Bass Boost feature, you can adjust its bass output, and this can be helpful if you’re listening to music that are bass-heavy, such as hip-hop, dance music and more.
