## Long description

The Ultimate Ears MEGABOOM 4 is a portable wireless Bluetooth speaker in blue that delivers powerful, immersive 360° stereo sound with deep, thundering bass. The cylindrical design produces even sound dispersion in all directions, while softer passive radiators extend low-frequency response for richer bass without distortion. The speaker supports up to 20 hours of battery life and a Bluetooth range of up to 45 m, and includes a MAGIC BUTTON for playback control and one-touch playlists via the UE \| BOOM app.
Advantages
MEGABOOM 4 offers loud and clear 360° audio with a balanced signature sound and enhanced bass compared with the previous generation. It is water-, dust- and drop-resistant and floats, so it can be used in pools, at the beach or in wet environments. The speaker supports PartyUp to pair over 150 compatible speakers and includes customizable EQ presets through the UE \| BOOM app. Exterior plastic components contain a minimum of 54% certified post-consumer recycled plastic by weight and the design considers end-of-life recycling.
Suitable for
