Product information

Description

Ultimate Ears MEGABOOM 4 is a stereo portable speaker in a cylindrical black enclosure that delivers immersive 360° sound and robust bass. The speaker uses wireless Bluetooth connectivity with the A2DP profile and supports an operating range up to 45 m. It incorporates a passive radiator sized 55×86 mm and produces a maximum sound pressure level of 91 dB. The compact, waterproof and impact-tolerant housing and long battery life make it suitable for home, outdoor and travel use.

Advantages

MEGABOOM 4 features a cylindrical design that radiates sound evenly in all directions, providing spatial stereo coverage without the need to reposition the unit. The passive radiator tuned for lower frequencies delivers deeper, richer bass while preserving clarity. Wireless Bluetooth connectivity enables straightforward pairing and playback from compatible devices using the A2DP profile, and the speaker’s durable build is resistant to water, dust and drops for reliable performance in varied environments.

  • Listening to music at home or in small gatherings
  • Outdoor activities and trips where portable, loud audio is needed

How to use

Charge the speaker before first use, then power it on and enable Bluetooth on your source device. Select the MEGABOOM 4 from the device’s Bluetooth list using the A2DP profile to start playback.
