If you remember, we have recently talked about a product from IO Data, headset wiREVO WBM-220, which I'm not liking in connection with described flaws and eccentricities. Today there will be about another gizmo, this time with an index of S300, it is the name displayed on the display. But the company's website, it is called differently. In general, mess with the names we should not worry, better look at the features of the product.
