Description

The Ultimate Ears WONDERBOOM 4 is an ultraportable stereo Bluetooth speaker in blue that delivers a bigger, crisp sound with pronounced bass from a compact cylindrical body. It features a passive radiator (46.1 x 65.2 mm), a maximum sound pressure level of 87 dB and a wireless Bluetooth range up to 40 meters. The speaker offers IP67 dust- and water-resistance, floats on water, and provides up to 14 hours of playtime, making it suitable for both indoor and outdoor use.

Advantages

WONDERBOOM 4 provides full, bass-rich stereo sound from a single compact speaker, with an Outdoor Boost mode for enhanced open-air performance and a Podcast Mode tuned for clear vocals. It supports quick one-tap Bluetooth pairing with Android devices, can be paired with a second WONDERBOOM 4 for true left/right stereo, and uses at least 31% certified post-consumer recycled plastic in its plastic parts. The design is drop-resistant to 5 feet and offers up to 40 meters of wireless range.

Suitable for

  • Listening to music at home, outdoors, or at small gatherings
