JBL PartyBox On-The-Go 2 Plus review: Portable sound meets AI karaoke
A great party needs more than just good company and a few drinks; it takes music that gets everyone in the mood to have a good time. A party speaker gives you powerful, room-filling sound and punchy bass that traditional speakers simply can’t match. Many models also have built-in lighting effects, wireless connectivity and long-lasting batteries, allowing you to keep the music going and create the perfect atmosphere wherever the party takes you. For a party speaker that delivers amazing sound and a lively atmosphere, we recommend the JBL PartyBox On-The-Go 2 Plus.

It also has a dynamic light show that syncs with your music.

Here’s our review of the JBL PartyBox On-The-Go 2 Plus, where we explore its design, portability, audio performance, AI karaoke features, connectivity, battery life and app to help buyers understand its value.
Design and portability Built for entertainment
Starting with its size, this party speaker has a compact footprint with a rectangular body. It measures 19.72″ long x 10.16″ wide and 8.70″ tall (50.1 x 25.8 x 22.1 cm) and weighs 14.22 lbs. (6.45 kg), offers portability without sacrificing speaker size. However, its weight makes it better suited for scheduled gatherings than daily commutes. The speaker also comes equipped with a flexible carrying case and a thick, wide shoulder strap that makes transport easier. Plus, its shoulder strap also has a built-in bottle opener on one end, making it easy to open bottles of drinks.
The JBL PartyBox On-The-Go 2 Plus also sports a sleek, modern design with a discreet appearance. Its body comes in a solid black color. In addition, the speaker also packs a durable, high-quality construction. Its housing partially contains post-consumer recycled plastic, while its packaging is made from FSC-certified paper printed with soy ink. The speaker also has an IPX4 splash-proof rating, meaning it can withstand accidental splashes and light rain.
JBL Pro Sound, Audio Specifications, and Dynamic Lightshow
At its core, the JBL PartyBox On-The-Go uses a speaker system powered by JBL Pro Sound technology. Its audio system combines two 0.75″ silk-dome tweeters with a 5.25″ woofer, which together deliver crisp, detailed sound. The tweeters reproduce vocals and higher frequency details, while the woofer handles lower frequencies with a deep, punchy bass.
This combination makes the speaker capable of delivering 100W RMS output, providing substantial power for indoor celebrations and smaller outdoor gatherings. The speaker offers a frequency response between 40 Hz and 20,000 Hz (-6dB), in addition to a signal-to-noise ratio of over 80dB.
In addition, the speaker also features a dynamic light show with glowing light patterns and strobe effects that sync with your music, helping to create a more engaging atmosphere when playing music.
AI-Powered Karaoke, Vocal Enhancement Features and Wireless Microphone
Another cool feature that makes the JBL PartyBox On-The-Go 2 Plus stand out is its integrated EasySing technology. Unlike traditional karaoke systems that require instrumental tracks, JBL’s EasySing technology uses advanced on-device AI to separate vocals from each track in real time, allowing users to reduce or completely remove the original vocals at the touch of a button.
In addition, the speaker has high-pitch enhancement, which helps you reach higher notes by supporting your upper range. This ensures that anyone singing through the speaker’s included microphone will always sound and be clear to those listening. It also has a natural reverb function that adds some depth to the microphone audio to help you sing with confidence.
The speaker also comes with a rechargeable wireless microphone with built-in feedback suppression, allowing users to sing loudly without stuttering. Its microphone has a frequency response between 50 Hz and 15,000 Hz. It uses 2.4Ghz connectivity, supports approximately 100 ft (30 m) range, and offers up to 10 hours of battery life. The speaker also comes with a microphone holder to store its microphone when not in use.
These features make the speaker particularly attractive for karaoke nights, family events and interactive entertainment.
User-friendly control panel
To control its operation, the speaker incorporates a button control panel with a simple interface that makes it easy to use. Located in the lower center, we have the speaker volume and connectivity controls. It has a play/pause button on the right, which also lets you skip songs while also doubling as a volume dial, plus a lightshow button on the left, which is used to turn the lights on or off, which can also be rotated to change the lighting effects. Sitting between these buttons, we have the Bluetooth Speaker, Auracast, and Bass Boost buttons.
Then on the top side we have the speaker microphone controls. Going from left to right, we have a microphone volume dial, an AI Vocal Removal button/dial that can be rotated for vocal removal adjustments between 0-100%, and a microphone echo button/dial to turn reverb on/off and adjust it.
The speaker’s microphone also incorporates its own AI Vocal Removal button, allowing you to perform the same action from the stage.
Connectivity, battery life and charging stations
The JBL PartyBox On-The-Go 2 Plus uses Bluetooth 5.4 connectivity for wireless streaming. It also incorporates a 3.5mm AUX input for wired audio sources. The speaker also supports stereo pairing, which allows two units to be paired for stereo sound. It also has Auracast support, which allows multiple JBL Auracast-enabled speakers to be connected wirelessly for an even bigger soundstage.
For its power, the speaker uses a replaceable 4,722mAh lithium-ion battery (34Wh / 7.2V) that offers up to 15 hours of playing time. As for the battery, the speaker uses an AC power cord. It takes about 3.5 hours to fully charge the speaker’s battery. The speaker also has a 10-minute quick charge function that can provide up to 80 additional minutes of playback.
JBL One App: personalized sound and easy control
The JBL One app (available for iOS and Android) lets you control most of the speaker functions remotely. Through it you can control and adjust the music settings, the equalizer of the app, and the light show effects of the speaker.
Things to consider before you buy
The JBL PartyBox On-The-Go 2 Plus offers an attractive combination of powerful sound, flexible connectivity, colorful lighting, and AI-assisted karaoke. Its 100W output, replaceable battery, wireless microphone, and EasySing technology make it especially suitable for social gatherings and entertainment-focused households.
Buyers looking for a lightweight everyday speaker will prefer something smaller. However, those who regularly host parties or karaoke sessions will find its integrated features compelling.
