JBL designed the PartyBox Encore2 for listening to vibrant music and singing karaoke. It includes two microphones and AI Sound Boost technology, and its design makes it convenient for outdoor use.
JBL PartyBox Encore2 Quick Review
Looks and Portability
PartyBox Encore2 has a square box design overall with sides measuring no more than 40 cm. The total weight of the speaker is about 6.4 kg; it is not difficult to carry it with one hand. An indispensable built-in handle for added convenience.
The manufacturer uses recycled plastic to make the speaker housing and finishes it with a rough surface to reduce the risk of scratches from sharp surfaces and to ensure the structure resists impacts.

This finish also does not leave fingerprints or sweat. However, some soft rubber areas on the control buttons or knobs may collect dust. This is unimportant because users can easily clean thanks to the IPX4 water resistance.

The speaker is suitable for outdoor use because it can withstand water splashes and light rain. The connection ports or battery cover are also lined with rubber to increase water and dust resistance.
PartyBox Encore2 has a 5.25-inch woofer and two 0.75-inch tweeters above the left and right corners. The large woofer helps it reproduce bass at intense levels. It is suitable for many types of music and listening contexts. This speaker model’s RMS power reaches 100W.
User Interface and Connectivity
The control keys and rubber handle are located on top of the speaker. The company can equip an accessory to prop up the phone if you want more.
The central control button system is located right next to the top of the speaker’s sound-oriented surface. There are two knobs for the lighting system and volume adjustment. The power, Bluetooth, Auracast, and Bass Boost buttons are designed with one-touch and easy-to-follow indicator lights.
Next, the speaker has two adjustment buttons for the two microphones. Volume and echo adjustment are the most commonly used features when singing karaoke. More broadly, you can use the app to adjust the bass and treble of the microphone.

The speaker’s connections are on the back, protected by a cover. The second source is via the AUX IN port next to Bluetooth. Next is the 6.3mm audio input port for musical instruments with separately adjustable volume. The USB-C port charges devices that need power, such as phone chargers.
The speaker is charged directly by AC 220V via an IEC-C7 wire. An additional DC charging source from USB-C would be perfect. A 34Wh battery (7.4V—4,722 mAh) can help the speaker operate for up to 15 hours.
Sound, Singing, and Smart Controls
JBL PartyBox is the name of the Encore2 application. Currently, JBL has many applications for many different product groups, perhaps to reserve experiences depending on the features of each product line.
The JBL PartyBox interface helps exploit all the features of the speaker line. Connect Bluetooth and access the application; the speaker will appear for users to access and control.


Notable customizations include an equalizer, sound profiles, lighting effects, and custom lighting profiles for the speaker’s control buttons.
In addition, the Effect Lab section helps you try DJing while playing music. Higher-end speakers will have a few hard keys on the speaker side.


The included microphone provides a swift response even when opening the app for management. The battery percentage is displayed, making it easy for users to monitor and recharge the battery proactively. The app can also adjust the microphone’s bass and treble.
Regarding sound technology, JBL said they integrated AI Sound Boost technology, which analyzes and optimizes sound quality in real time. The app can also customize the equalizer to suit each type of music played according to your taste.

Like recent JBL products, the Auracast device connection technology integrated on the Encore2 helps users expand JBL audio devices that also use this connection. I tried two JBL Go 4 (REVIEW) speakers to see if they could play music. I found the quality stable, without delay, and with easy connection. The phone does not need to be paired with the speakers; the speakers with the Auracast feature automatically connect.
Final Line
The PartyBox Encore2 is made for those who want music, mics, and portability without the fuss. It’s light enough to carry, built to handle the outdoors, and quick to connect with Bluetooth or Auracast. It efficiently handles karaoke and casual music sessions with two microphones and app-based controls—no gimmicks—just solid sound and smart design.
