JBL just dropped the Boombox 4 in China, and it appears to pack some decent upgrades over its predecessor. They're positioning this as their "flagship portable speaker" with enough power to fill any outdoor space. So, let's dive into this article, where I will discuss everything about the latest JBL Boombox 4, including its expected price in Nepal, specifications, and availability.
JBL Boombox 4 Overview
Design and Portability
The Boombox 4 gets a complete redesign that's actually 12% lighter than the Boombox 3, which is impressive considering the power bump. At 5.89 kg, it's indeed a hefty speaker, but you also get an integrated handle, such that you can carry this around anywhere. You're getting three color options: black, blue, and camouflage.
The dimensions come in at 506.4 x 262.9 x 212.9 mm, so this is quite big, and as mentioned earlier, it's definitely portable but not exactly pocket-friendly. But then again, you're not buying a Boombox for subtle background music.
Sound and power
JBL Boombox 4 packs 7 drivers total – dual 5-inch woofers, dual 0.75-inch tweeters, and 3 passive radiators. Power output hits 210W RMS when plugged in and drops to 180W RMS on battery.
If you wonder if this also features some kind of AI gimmick, then well, your intuition was correct as they've added an AI Sound Boost algorithm that's supposed to deliver more "dynamic and balanced audio." Plus, there's a dedicated Bass Boost button with two levels, because apparently one level of earth-shaking bass wasn't enough.

Battery and Charging
The 99Wh internal battery on the JBL Boombox 4 delivers 28 hours of playback, extendable to 34 hours with something called Playtime Boost. It doubles as a 30W power bank with 20V/1.5A PPS output. So you can charge your phone while the speaker is blasting tunes. Fast charging works through both USB-C and AC ports.
Connectivity and Features
You're getting Bluetooth 5.4 with Auracast support for multi-speaker pairing. It can connect to two Bluetooth devices simultaneously, so switching between phones won't be a hassle.
The USB-C port supports lossless playback with a built-in DAC. And with an IP68 rating, you can literally submerge this thing without worrying.
