## Description

Enjoy surprisingly big 360-degree sound from this compact, waterproof Bluetooth speaker with up to 14 hours of playtime, outdoor boost, and podcast mode.

Review: Small but mighty - I bought this speaker as my old one was no longer loud enough for my needs, and after trying a colleagues wonderboom 2. With outdoor boost activated (what a brilliant function!), one of these is loud enough to project backing tracks 30+ children playing in an ensemble/orchestra. The sound quality is great. I'm noticing details in music that didn't quite come across on my old speaker. And also, the 360° omnidirectional aspect means the sound is equally audible to both orchestra and audience. I'm aware that you can pair 2 wonderbooms, so if I have any need for extra loudness in the future, I'll definitely just get an extra one rather than looking to replace it with something different. The battery lasts a decent amount of time, and it powers itself off if unused for 15mins, which is very helpful. My only small snag is that you can't find out the precise battery level. It just tells you whether it's within 'normal battery range' (which is anywhere between 36-100%) or if it's low. Using a USB-C cable for charging means I can just use my phone charger, rather than having extra cables lying around. It pairs easily with my iPad and phone, and I haven't had any lag issues etc. I haven't tested out the range, but I believe this is meant to be a decent distance. The price tag seemed a bit much, but the quality is definitely worth it, especially if like me, it's needed for work.
Review: Outstanding! - This is a super little speaker with sound quality MUCH bigger than it's small and easy to carry size. Perfect for outdoor trips / hols. Even floats in the pool. Really pleased.
