Whether you plan to spend your time this summer at the beach, at campsites, at the lake, or anywhere else (even right outside your home), your audio enjoyment will take a major step up through the JBL Boombox 4 speaker. Within the casing, JBL has packed in two large woofers, two tweeters, and three passive radiators, “so every track hits harder and sounds cleaner,” complete with an IP68 waterproof and dustproof construction.
Not only that, but it comes with AI Sound Boost that analyzes music in real time and adjusts its own settings for more power with less distortion. The battery here gives you up to 34 hours of playtime, and can even be conveniently replaced so you won’t ever have to buy an all-new speaker.
