The all-new HyperBoom Speaker from Ultimate Ears is the largest and loudest Bluetooth speaker in the brand’s lineup, powerful enough for party-pumping bass and crisp, room-filling sound. The rectangular tower features a sleek, streamlined design with simple, push-button controls & ports aplenty. Including an optical port. Linked with the Ultimate Ears app, it streams seamlessly using Spotify, Amazon Music, Apple Music, or Deezer. The speaker array consists of two 4.5-inch woofers, two 1-inch tweeters, and two 3.5-inch passive radiators; all of rated IPX4 for weather resistance. Battery life is up to 24-hours.
