Compact Bluetooth Speaker for Outdoor Use

The Ultimate Ears WONDERBOOM 984-000842 is a portable wireless speaker built for travel and outdoor activity. Its IP67 rating confirms protection against dust and immersion in water up to one metre for thirty minutes. The Cashmere Pink finish distinguishes this unit visually. It suits listeners who want a durable, grab-and-go audio device.

Wireless Range and Battery Constraints

Bluetooth connectivity extends to 33 metres or 100 feet in open space, though walls and interference will reduce the practical distance. The rechargeable lithium-ion battery delivers up to 10 hours of playback and requires 2.8 hours to refill via micro-USB. Users needing multi-day operation away from a charger should plan accordingly.

360-Degree Sound from Dual Drivers

Two 40 mm active drivers and two 46.1 mm passive radiators produce omnidirectional audio across a frequency range of 80 Hz to 20 kHz with a maximum output of 86 dBC. The 360-degree dispersion fills a room or patio evenly. Buyers who prioritise deep sub-bass extension or stereo imaging from a single enclosure will find the physical limits of this form factor restrictive.
