JBL Boombox 4
KSh 62,000.00
Description
Powerful JBL Pro Sound
The JBL Boombox 4 is built for listeners who want powerful sound without being tied to a home setup. Its redesigned audio system combines two 5-inch woofers, two 0.75-inch tweeters and three passive radiators to deliver deep bass, clear vocals and detailed high frequencies.
With up to 130W RMS total output when connected to AC power and a frequency response of 37Hz–20kHz, the Boombox 4 is designed to deliver impressive sound for both indoor and outdoor listening.
AI Sound Boost
JBL’s AI Sound Boost analyzes your music in real time and adjusts the speaker’s output to provide more power while helping reduce distortion, particularly when playing music at higher volume levels.
Choose Your Bass
The Boombox 4 gives you two dedicated Bass Boost modes:
- Deep Bass — fuller, deeper low frequencies
- Punchy Bass — tighter and more energetic bass
This lets you adjust the sound depending on the music, environment or mood.
Up to 34 Hours of Playtime
Keep your music going for longer with the Boombox 4’s large 99.02Wh rechargeable lithium-ion battery.
You get up to 28 hours of normal playback, while JBL Playtime Boost can add up to another 6 hours, giving you a maximum advertised playtime of 34 hours depending on volume and content. Charging takes approximately 3 hours.
Built for Outdoor Entertainment
The JBL Boombox 4 features an IP68 rating, meaning it is designed to withstand both water and dust. This makes it suitable for outdoor parties, poolside entertainment, camping, picnics and other environments where your speaker may encounter water or dirt.
Connect Multiple Speakers with Auracast
With Auracast, compatible JBL speakers can be connected together to create a wider sound experience. You can also stereo-pair two compatible Boombox 4 speakers for an expanded soundstage.
Bluetooth 5.4
Bluetooth 5.4 provides modern wireless connectivity for streaming music from smartphones, tablets, laptops and other compatible devices. The speaker supports A2DP 1.4 and AVRCP 1.6 Bluetooth profiles.
USB-C Lossless Audio
For listeners who want high-quality wired playback, the Boombox 4 supports lossless audio through USB-C when used with compatible devices and lossless content. The USB-C connection can also be used as a power output for charging compatible devices.
Replaceable Battery
Unlike many portable speakers with permanently integrated batteries, the Boombox 4 features a replaceable rechargeable battery, giving the speaker a longer potential service life. The replacement battery is sold separately.
