Big Bass You Can Feel, Outdoors or In: soundcore Boom 2 delivers deep, punchy bass you can feel. As an outdoor bluetooth speaker, it features a dedicated subwoofer and BassUp 2.0 technology to deliver deeper, harder-hitting bass — helping fill open spaces like campsites, patios, and backyards with powerful sound. Clear, Balanced Sound at Any Volume: soundcore Boom 2 combines crisp highs, detailed mids, and rich bass in one powerful outdoor bluetooth speaker. Smart tuning keeps the sound clear and balanced, whether you’re relaxing with friends or turning things up. All‑Day Playtime, Plus Backup Power: Take soundcore Boom 2 on all-day adventures with up to 24 hours of playtime on a single charge. When phones start running low, the built-in power bank keeps them going — and when the speaker itself needs a top-up, fast charging gets it back quickly. Perfect for trips where outlets aren't an option. (Playtime varies by volume level and audio content.)
