Review: Does a job - I've been on the market for a multi-room speaker system for a couple of years and finally I decided to take the plunge with these. A lot of these types of products require you to download an app and/or create an account of some kind, but all I wanted was to be able to pair and play; thankfully, this system does exactly that. Very simple to set up: just put the base somewhere handy, switch it on, pair it with the device of your choice (PC in my case), turn on the speakers, and you're sorted. You can also connect the base to your audio source physically if it has the right optical or auxiliary output. For their size and price point the sound quality of the speakers is perfectly acceptable, and they have a nice sturdy feel to them. The ability to use a single speaker on its own instead of as part of the multi-room system is a nice bonus too. All in all I'm very happy with this purchase, and will most likely be buying an additional speaker soon. If you're looking for a similar system and aren't a hardcore audiophile who must have the absolute best quality always, I'd gladly recommend this to you.

### ⭐⭐⭐⭐⭐ Great Sound

Great Speakers Great Sound Sometimes disconnects the main device to Tablet, have to reboot to connect but otherwise Great Bluetooth Speakers Battery for 6 hours playing music

### ⭐⭐⭐⭐ So easy to set up.
*by C***S on 14 January 2025*

Looks good. Was super easy to set up. The range on the transmitter to the speakers is obviously limited by walls etc but it seemed ok across our house. Furthest speaker was 20 m and through a solid wall. Sound quality was pretty decent.
