Stereo Portable Speaker Ultimate Ears Hyperboom Black

The Ultimate Ears Hyperboom is a stereo portable speaker engineered for large, versatile listening environments. It delivers powerful, balanced sound with extended bass and a wide frequency range from 45 to 20,000 Hz. The Hyperboom supports both wired and wireless connections — including Bluetooth (A2DP), auxiliary and optical inputs — and offers multi-device playback, adaptive EQ, splash protection (IPX4) and up to 24 hours of battery-powered playtime. Its black, diamond-influenced rectangular design with a pull-out strap combines portability with a robust acoustic layout.

It accepts simultaneous connections from multiple devices and lets users switch sources instantly via button or app. The speaker is splash-proof (IPX4), features adaptive EQ that optimises sound for the room, and includes both wired (auxiliary and optical) and wireless (Bluetooth) inputs. Large passive radiators, precision woofers and soft-dome tweeters provide high-fidelity audio across volumes, and a rechargeable battery supports up to 24 hours of playback.

How to use

Charge the Hyperboom fully or connect it to AC power. For Bluetooth playback, enable Bluetooth on your device and pair using the speaker’s pairing procedure; the speaker supports A2DP profile. To use wired sources, connect via the auxiliary or optical input and select the input with the source selector button. To switch between up to four connected devices, press the source selector or use the companion app; playback switches without interrupting the music. For multi-speaker setups, use the app to add other BOOM, MEGABOOM or Hyperboom speakers and adjust volume and grouping as required.

Usage recommendations

Place the Hyperboom on a stable surface away from direct exposure to heavy rain. Allow space around the speaker for optimal passive radiator movement and use the adaptive EQ feature when relocating the speaker to a new room or outdoor area to ensure balanced sound. Wipe off splashes promptly and avoid submersion. For extended listening, keep the speaker connected to AC power when battery runtime is not required.
