The JBL PartyBox Club 120 is a mid-range party speaker with a customizable RGB lightshow and an adjustable 'Bass Boost' mode. It picks up where its sibling, the JBL PartyBox 110, left off with a similarly rugged design and intuitive controls. It's also rated IPX4 for resistance against water splashes and comes with mic and instrument inputs to facilitate any spontaneous karaoke shenanigans. One notable point of departure is the inclusion of a swappable battery pack, which opens up the possibility of extending battery life beyond the advertised 12 hours.
Our Verdict
The JBL PartyBox Club 120 is good for music. True to its name, it produces a bass-heavy sound that's well-suited to club music; from house to hip-hop, this speaker adds dynamism to kicks and basslines. Its mid-range response is relatively balanced, meaning vocals and lead instruments come through clearly. You can always adjust the sound via the in-app EQ and presets. This speaker gets impressively loud, though some compression at max volume can cause drums to lose a bit of punch. While its forward-facing design means audio doesn't sound consistent from every angle, it can play stereo content without downmixing to mono.
- Two-way Bluetooth connectivity.
- IPX4 rating against water splashes.
- Swappable battery pack design.
- Cumbersome to carry, even with the handles.
The JBL PartyBox Club 120 is okay for videos and movies. It delivers an exciting, bass-heavy sound that's well-suited to thrillers and action movies and can get loud enough for a home viewing party. It can play stereo content without downmixing to mono, so you'll get some separation between left and right channels in movie audio. That said, its latency on iOS devices isn't ideal and can introduce audiovisual synchronization errors. It's worse with Android devices, so you'll need to be wary of sync errors between your audio and video. That said, different devices and apps compensate for this in different ways.
- Two-way Bluetooth connectivity.
- Graphic EQ and presets via the companion app.
- Latency with Android devices is quite high.
- Cumbersome to carry, even with the handles.
The JBL PartyBox Club 120 is a good fit for podcasts. It reproduces mid- and treble-range frequencies with plenty of detail, so the voices of your favorite podcasters will sound clear and natural. There's even a 'Vocal' EQ setting you can use to further emphasize these frequencies. While it can get pretty loud, its directivity isn't the best, so audio won't sound consistent across every listening angle. It's also not as portable as other Bluetooth speakers, so it's best not to move around too much when listening to a podcast.
- Two-way Bluetooth connectivity.
- Swappable battery pack design.
- Cumbersome to carry, even with the handles.
The JBL PartyBox Club 120 doesn't have voice assistant features.
The JBL PartyBox Club 120 is a very good outdoor speaker. It offers more than 10 hours of continuous battery life, ideal for soundtracking your all-day BBQ without worrying about running out of juice. You can even buy an extra swappable battery pack if you feel like taking the party into the night. It also gets impressively loud and delivers a fun, bass-heavy sound that's well-suited to both outdoor dance floors and karaoke. While there are built-in carrying handles, it's still not the most portable speaker due to its bulky design. It's decently well-constructed, thanks to its thick plastic build and IPX4 rating against water splashes.
- Two-way Bluetooth connectivity.
- IPX4 rating against water splashes.
- Swappable battery pack design.
- Cumbersome to carry, even with the handles.

Popular Speaker Comparisons
The JBL PartyBox Club 120 is a mid-range party speaker. It offers a feature set very similar to the JBL PartyBox 110, which is comparable in price. Both can get similarly loud and are equally portable, thanks to their built-in carrying handle. That said, the PartyBox Club 120 delivers much more bass by default, which is better for getting a party started. And the PartyBox Club 120 also features a swappable battery pack design so you can keep the party going for longer, although it has a shorter continuous battery life than the PartyBox 110. If you're looking for something to soundtrack even larger parties, you can also check out the louder JBL PartyBox 710. However, the extra volume comes at the expense of extra heft and the inability to operate off battery power.

The JBL PartyBox 110 and the JBL PartyBox Club 120 are similarly sized party speakers with RGB light shows, but you should probably buy the Club 120. That's mainly because the Club 120 has a bassier sound that's much better for getting a party started. However, the devices are pretty evenly matched in almost every regard, as both are well-built, have IPX4 ratings against splash damage, and are similarly loud. The PartyBox 110 even has a longer continuous battery life. That said, the PartyBox Club 120 features a swappable battery pack design, so you can replace an empty battery immediately without waiting for it to recharge.
The JBL Partybox Club 120 is a better choice if you're looking to take the party to the next level, though the JBL Boombox 4 is more versatile. The Boombox features a much longer battery life, a lighter, less bulky build (that can be carried with one hand), and Bluetooth LE connectivity for lower-latency playback with select Android devices. It also gets louder than the PartyBox. On the other hand, the PartyBox comes with a host of party-friendly features, like mic inputs, DJ effects, and customizable lighting.
The Sony SRS-XV500 and the JBL PartyBox Club 120 are both similarly sized party speakers. The JBL has a more bass-heavy sound and better directivity. While both speakers can get equally as loud, there's less compression at max volume with the JBL. As a result, the JBL is a better fit for getting a dance floor going at your next party, although you may prefer the Sony's more balanced sound profile. The Sony model also offers longer continuous battery life, though it lacks the JBL speaker's swappable battery. It also has significantly fewer audiovisual synchronization errors on Android and iOS devices, so it's better suited for users who watch movies and videos.
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 and can achieve comparable bass levels. The Stage 320 can get louder, though. Both speakers have a similar build quality, IPX4 ratings, and 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.
