JBL Boombox 4 Portable Bluetooth Speaker
The JBL Boombox 4 is a powerful portable Bluetooth speaker designed to deliver JBL's most powerful portable sound experience with deep, punchy bass and clear, detailed highs. Its redesigned audio system combines two massive woofers, two tweeters and three passive radiators to produce an immersive listening experience with impressive low-frequency performance. AI Sound Boost analyzes music in real time to enhance output power while reducing distortion, helping maintain powerful and clearer sound even at high volume levels. The speaker provides up to 34 hours of total playtime, combining up to 28 hours of standard playback with an additional 6 hours through Playtime Boost, making it suitable for extended parties, beach days, backyard gatherings and weekend adventures. Built for demanding outdoor environments, its IP68 waterproof and dustproof construction provides enhanced protection against water and dust. Auracast™ multi-speaker connectivity allows two Boombox 4 speakers to be paired for stereo sound or multiple compatible JBL Auracast-enabled speakers to be connected for a wider synchronized audio experience. The USB-C port also supports lossless audio playback when connected to a compatible laptop or audio source, allowing greater detail to be retained from supported lossless content. Despite its powerful sound output, the redesigned Boombox 4 features a lighter build that makes it easier to transport. Available in Black, Blue and Squad finishes, it combines powerful JBL Pro Sound, intelligent audio processing, extended battery life and rugged outdoor durability in a portable speaker designed for large-scale listening.
