I've purchased two of these, the first one worked well so I bought the second to get stereo sound.
They pair easily and sound pretty good for the price in stereo mode. However, in Stereo mode they occasionally cut-out (sounds like a skip in the music) sporadically, sometimes a minute or two apart or seconds apart. I'm thinking this is a firmware issue.
Unfortunately, W-King has not responded to multiple emails asking for support or a firmware update to fix this.
The speakers work fine individually, but the sound is much better with two in stereo. Unfortunately, W-King doesn't seem to care that they cut-out and does not provide after sales support.
