Ultimate Ears Wonderboom 4 14 Hours Portable Speaker
Product description
This compact portable waterproof speaker delivers bold 360-degree sound for outdoor and home use, with a battery that lasts up to 14 hours according to the manufacturer. It suits garden parties, pool days and casual listening where robust, easy-to-carry audio matters.
What matters most
The Wonderboom 4 focuses on punchy, balanced playback from a small enclosure. Outdoor Boost adds extra presence for open spaces, while Podcast Mode clarifies voices for spoken-word content. If you prioritise portability, the loop and lightweight build make it simple to grab and go, and if you prefer louder stereo performance you can pair two units for true left and right channels.

Benefits
Durability stands out, the speaker is dust-resistant, drop-tested from 1.5 m and floats, so it copes well near water. Sound is tuned to feel bigger than the size suggests, and the Outdoor Boost button helps maintain clarity in louder environments. The design keeps controls simple, which is handy when you want music without fuss.
Who it suits
It’s a good fit if you want a rugged, easy-to-use speaker for outdoor gatherings, beach trips or showers, and you value long battery life for day-long use. It may not suit you if you need very high fidelity at extreme volumes, because small portable speakers have inherent limits in bass and headroom.
