    • Good speakers at a great price.
Color: CK-5212-NEW
The media could not be loaded. I am not an audiophile, but I do like my music to sound good. I was looking for Bluetooth speakers for my new PC build that I could put on the desk, away from the PC case. The last Bluetooth speakers I bought were a real disappointment and had too much lag especially noticeable when watching movies. But I liked the look of the Cinnkeyi speakers and I figured with four speaker included, it couldn't sound too bad. I have been very surprised how great the sound is coming from such a small speaker system. Granted, I use these in my studio which is a converted bedroom and not a big space. But these speaker not only provide all the volume I need but the depth of sound is really impressive. If you are looking for high quality speakers on a budget, then these Cinnkeyi speakers are a great choice. ... show more

Color: CK-5212-NEW
Very low sound. They look nice, install easy and sound decent at their low volume. I wasn't expecting super sound at the price but they have less volume than any PC or desktop speakers I've ever bought.

I didn't expect much and that's what I got. The sound quality is just okay but I put it in my shop steaming music fro YouTube. It's okay for that.
