I’ve been using the BOOM 4 for a few months now, and it’s become my trusty sidekick—whether I’m chilling in a hotel room or lounging by the pool. The size is perfect for tossing into my backpack, and the sound? Surprisingly big for something so compact.

One thing that blew me away was the battery life. I took it on a weekend trip without charging, and it lasted the entire time—no dead speaker during my morning coffee playlist. And yes, it survived an accidental dunk in the pool (IPX7 waterproofing FTW).

The 360-degree sound fills small spaces effortlessly. Podcasts sound crystal clear, though I’ll admit bass-heavy music isn’t its strongest suit. But for casual listening, it’s more than enough. The Magic Button is a game-changer—skipping tracks without grabbing my phone is oddly satisfying.

Pro tip: Pair two BOOM 4s via the app for stereo sound. I did this during a BBQ, and suddenly my tiny patio felt like a mini concert venue. For travelers or minimalists who want reliable sound without bulk, this little cylinder delivers.
