Logitech Ultimate Ears WONDERBOOM 4 2.0 Bluetooth Portable speaker, Black

The Ultimate Ears WONDERBOOM 4 is a portable speaker designed to deliver 360-degree audio from a compact, cylindrical chassis. Its internal driver configuration aims to produce clear sound with a notable bass response for its size. An "Outdoor Boost" function adjusts the audio equalization for improved performance in open-air environments. For a wider soundstage, two WONDERBOOM 4 speakers can be wirelessly connected to create a 2.0 stereo pair.

This device features a durable construction with an IP67 rating, indicating resistance to both dust and water ingress. The speaker is also engineered to be drop-resistant and is buoyant, allowing it to float. It connects to source devices via Bluetooth 5.0, which provides a wireless range of up to 40 meters. The integrated lithium-ion battery supports up to 14 hours of playback and recharges through a USB-C port.
