Overview

Listen to your favorite audio out in the backyard or by the pool with the blue-colored The Magic Of Ultimate Ears Wonderboom 4 Wireless Bluetooth Speaker 2.0 Edition [roCYpjUb] from Logitech. The WONDERBOOM 4's floatable, submergible, dustproof design gives you piece of mind when using it by the pool or at the beach. Use the one-tap Outdoor Boost function to increase the volume when outside to better hear your music, or activate Podcast Mode and relax to an episode with vocals that sound rich and clear. Any type of audio enjoys 360° of sound with crisp and balanced sound with punchy bass, thanks to dual 1.6" active drivers and a pair of passive radiators.

Stereo Sound
With an additional WONDERBOOM 4, you can pair the two to either double the soundstage, or to use them for true stereo sound.
Outdoor Boost
While the WONDERBOOM 4 is designed to primarily be used outdoors; backyards, parks, and pools can be noisy places to enjoy music. Thankfully with the WONDERBOOM 4, you just need to tap Outdoor Boost for louder and more powerful audio playback.
Environmentally Constructed
With an eye on sustainability, at least 31% of all plastic parts on the MEGABOOM 4 are made from post-consumer recycled plastic by weight.
Additional Features
  • Up to 14 hours of playback
  • Bluetooth range of up to 131'
  • Drop-proof from up to 5'
  • Connect up to two wireless devices at once
  • Two 1.6" active drivers with dual passive radiators
  • Integrated carry loop
