Why Buy?
Big sound that follows you everywhere
The Ultimate Ears Wonderboom 4 delivers surprisingly powerful 360-degree sound from a compact speaker that fits in your hand, giving you 14 hours of clear, bass-rich music wherever your day takes you.
This tough little speaker handles real life without fuss — it's completely waterproof, dustproof, and floats, so pool parties, beach trips, and shower sing-alongs are all fair game. The 40-metre Bluetooth range lets you move freely around your home or campsite without losing connection. When you need extra volume outdoors, Outdoor Boost adjusts the sound for open spaces, while Podcast Mode makes voices crystal clear for your favourite shows.
At home or away, it just works — simple controls, reliable connection, and a handy loop for easy carrying. The compact design slips into any bag, and if you want even bigger sound, pair two speakers together for true stereo. It charges via USB-C and the cobalt blue finish looks good anywhere you place it.

- You want music that follows you from kitchen to backyard to beach
- Your weekends involve pools, camping, or outdoor entertaining
- You listen to podcasts while cooking, gardening, or getting ready
- You need a speaker tough enough for kids and clumsy moments
- You want all-day battery life without carrying chargers around
