Review: Good little speaker - Not bad sound from this little speaker, was worth the purchase
Review: No frills, just a decent speaker - I like it, I've heard others say it's not loud enough.....they must be site DJs! It's plenty loud, I don't want to annoy my customers or those round about me! I cheated and bought the converter to use it with DeWalt batteries! Okay, i did buy an Einhell battery eventually as there's some good deals on them in some desertcart shops. Lets me use my mobile with Spotify for sounds when I'm working.

### ⭐⭐⭐⭐⭐ Good little speaker
*by C***U on 22 July 2025*

### ⭐⭐⭐⭐⭐ No frills, just a decent speaker
*by S***G on 3 November 2024*

I like it, I've heard others say it's not loud enough.....they must be site DJs! It's plenty loud, I don't want to annoy my customers or those round about me!

### ⭐⭐⭐ Neat little speaker, NOT a BoomBox!
*by R***D on 27 December 2024*

This is a neat speaker that works with all those batteries you've got and will probably be where your old, tired, batteries end up being used. It pairs easily (Android at least) and is small enough to sit anywhere while you work. It's only problem is that it's not very loud. Given it has a passive speaker on each end you'd expect to have a bit more oomph! I've got a Bose speaker in the kitchen that blows this thing's socks off for bass. You do get a USB socket, that makes the batteries power available and an AUX socket for those who like a cable rather than Bluetooth. In summary - - neat enough for your garden shed or garage, - not loud enough for a workshop....and - would be completely lost on a building site.
