Ultimate Ears MEGABOOM 4 Portable Waterproof Speaker – Lilac, 360° Sound, 20-Hour Battery, 147 ft Range

Immersive sound that travels with you

The Ultimate Ears MEGABOOM 4 is built for big moments and everyday listening alike. Its 360-degree sound fills a courtyard, living room, or campsite with a balanced bass profile that lets highs, mids, and lows live in harmony. Picture crisp detail in the treble and a warm, chunky foundation in the bass, all without the usual harshness as the volume rises. This speaker isn’t just loud—it’s thoughtfully tuned to keep vocals clear and music intimate in the same space.

With a robust 20-hour battery, you can keep the party going from late afternoon into the evening. Charging is simple via USB-C (cable not included), so a quick top-up between sets is easy. For longer events, the MEGABOOM 4 travels light, so you can move sound where you need it without carrying extra gear.
