Review: 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.
Review: Super ! Guter Klang.. leicht zu bedienen.

We love our speakers. I had a single speaker, but both my husband and I are hard of hearing and need to have a speaker near our good ear. Now we each have one and the sound is awesome. We can each have the volume exactly right for our own need. When the cleaning lady comes in, she is able to put the third speaker wherever she is working. Usually though, I keep the third speaker charging and rotate the one on charge. I had trouble setting them up until I realized that the speaker won't work while it is charging. Once I understood that, it was easy.
