The JBL PartyBox 300 is a powerful, battery-powered portable Bluetooth party speaker designed to bring high-energy sound to any gathering. Featuring dual 6.5-inch woofers and three 2.25-inch tweeters, it delivers room-filling audio at high volumes with JBL's signature sound signature and a Bass Boost mode for extra low-end impact.

The speaker's eye-catching design includes circular RGB LED lighting with multiple modes—Meter, Pulse, and Party—that pulse and react to the music. It can be positioned vertically or horizontally, and the tweeters automatically adjust to maintain proper stereo imaging in either orientation. With an 18-hour rechargeable battery and 12V DC input compatibility, the PartyBox 300 is built for all-day use indoors and outdoors alike.

Connectivity is versatile: stream music wirelessly over Bluetooth, play directly from a USB flash drive, or plug in a microphone or guitar via the dedicated 1/4-inch inputs to use it as a PA system. A built-in USB charging port lets you keep your devices powered. Two PartyBox 300 speakers can be wirelessly linked in True Wireless Stereo (TWS) mode for a larger stereo setup, or connected via RCA output to RCA input for a wired stereo pair.
