To potential buyers (of more than one speaker): Note that these are not the Duo version of these speakers. They cannot be connected to each other to produce stereo sound. Also, there is no mike in these ones.
I just received the 2 I bought last year, which I bought thinking I could connect the two together. These are the original swimmers, now discontinued.

To Woot Staff: This mistake in the product description seems to have happened several times… What gives?
