Logitech 984-001591 Hyperboom Wireless Bluetooth Speaker Renewed

The Ultimate Ears Hyperboom (sold under Logitech, its parent company) is a powerhouse portable speaker engineered for large-scale sound. Equipped with two 4.5-inch woofers, two 1-inch tweeters, and two passive radiators, it produces deep, booming bass and detailed highs that can fill a backyard, garage, or large living room with ease. Adaptive EQ technology analyzes the speaker's surroundings and automatically tunes the audio output for optimal performance whether it's placed in a corner, against a wall, or in the center of a room.

With up to 24 hours of playback on a single charge, the Hyperboom is built for extended gatherings without the need for a power outlet. Its IPX4 splash-proof rating provides peace of mind around pools and drinks, while the USB charge-out port means it can double as a portable power bank for smartphones. Connectivity is versatile, with Bluetooth 4.2–5.0 supporting wireless streaming at up to 150 feet, plus optical and auxiliary inputs for wired sources. At 13 pounds, the Hyperboom prioritizes acoustic performance over ultralight portability — this is a speaker you set up and let dominate the soundtrack. This renewed unit has been professionally inspected and tested to perform like new.
