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-shaped body. It measures 19.72″ long by 10.16″ wide by 8.70″ tall (50.1 x 25.8 x 22.1 cm) and weighs 14.22 lbs. (6.45 kg), offering portability without sacrificing speaker size. However, its weight makes it better suited to planned gatherings than everyday commuting. The speaker also comes equipped with a flexible carrying handle and a thick, wide shoulder strap that make transportation easier. Plus, its shoulder strap also features a built-in bottle opener at one end, making it easy to open bottled 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. Moreover, the speaker also packs a durable, high-quality construction. Its housing partially incorporates post-consumer recycled plastic, while its packaging is made from FSC-certified paper printed with soy ink. The speaker also has an IPX4 splashproof 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), alongside a signal-to-noise ratio exceeding 80dB.
In addition, the speaker also features a dynamic lightshow with glowing light patterns and strobe effects that sync to your music, which helps create a more engaging atmosphere during music playback.
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 any track in real time, allowing users to reduce or completely remove original vocals at the touch of a button.
Additionally, the speaker features high-pitch enhancement, which helps you reach higher notes by supporting your upper range. This ensures anyone singing through the speaker’s included microphone always sounds load and clear to those listening. It also features a natural reverb function, which adds some depth to 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 loud without any surprise screeches. Its microphone has a frequency response between 50 Hz to 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 for storing its microphone when not in use.
These features make the speaker especially appealing for karaoke nights, family events, and interactive entertainment.
User-Friendly Control Panel
To control its operation, the speaker integrates a button control panel with a simple interface that makes it easy to use. Located at the bottom center, we have the speaker’s volume and connectivity controls. It features a Play/Pause button on the right that also lets you skip songs, while also doubling as a volume dial, plus a Lightshow button on the left that’s used to turn the lights On or Off, which can also be rotated to change lighting effects. Sitting between these buttons, we have the speaker’s Bluetooth, Auracast, and Bass Boost buttons.
Then at the top side, we have the speaker’s 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 for turning reverb On/Off and adjusting it.
The speaker’s microphone also integrates its own AI Vocal Removal button, letting you perform the same action from the stage.
Connectivity, Battery Life and Charging
The JBL PartyBox On-The-Go 2 Plus uses Bluetooth 5.4 connectivity for wireless streaming. It also integrates a 3.5mm AUX input for wired audio sources. The speaker also supports stereo pairing, allowing for two units to be paired for stereo sound. It also features Auracast support, allowing 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 can offer up to 15 hours of playtime. As for recharging its battery, the speaker uses an AC power cable. It takes around 3.5 hours for the speaker’s battery to fully charge. The speaker also features a 10-minute quick charging function, which 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 remotely control most of the speaker’s functions. Through it, you can control and adjust music settings, the app’s equalizer, and the speaker’s lightshow effects.
Things to Consider Before Buying
The JBL PartyBox On-The-Go 2 Plus offers an appealing combination of powerful sound, flexible connectivity, colorful lighting, and AI-assisted karaoke. Its 100W output, replaceable battery, wireless microphone, and EasySing technology make it particularly suitable for social gatherings and entertainment-focused households.
Buyers seeking a lightweight everyday speaker may prefer something smaller. However, those who regularly host parties or karaoke sessions will find its integrated features compelling. Overall, the JBL PartyBox On-The-Go 2 Plus presents a versatile entertainment solution that brings music and interactive performances together.
