The Ultimate Ears BOOM 4 is a portable Bluetooth speaker with 360-degree sound, deep bass, and up to 15 hours of battery life, suited to listeners who want music for outdoor gatherings or everyday use away from an outlet.
Recommended For
- People taking music to the pool, beach, campsite, or park who want a compact, water- and dust-resistant speaker that can travel in a bag or clip onto one.
- People sharing podcasts, radio, or background music around a kitchen, desk, or small outdoor group who value consistent 360-degree sound more than filling a large space.
- Travelers and day-trip users who want a portable Bluetooth speaker for several listening sessions between charges, rather than a stationary home audio system.
- Owners of compatible Ultimate Ears BOOM, MEGABOOM, EVERBOOM, EPICBOOM, or HYPERBOOM speakers who want to link speakers through the app for shared listening.
