Bottom Line
The JBL Boombox 4 is one of the most well-rounded portable speakers we've analyzed, with specs that genuinely back up the overwhelmingly positive reviews. With up to 34 hours of battery life, rugged waterproof construction, and bass that seriously punches above its weight class, this speaker is built for adventure. Whether you're powering a backyard party or an outdoor event with dozens of people, it delivers professional-quality sound with impressive clarity and depth. Just keep in mind the lack of an aux port and no support for high-fidelity codecs—if you're comfortable with Bluetooth and USB-C connectivity, this is legitimately one of the best portable speakers available.
