Mouse pads are the wrong size and not to oem specs. I bought 2 orders of this product to give as gifts to my childs volleyball team. Even weirder, I use a small in the Apple tips, but these mediums work great for me. Aside from the fit, the quality was good and the designs were adorable. All I asked for was some sort of resolution. No balanced connector, but I?ll explain why it isn?t even necessary anymore. I have contacted primos and will post an update on what they say. I can be streaming from a local server or Spotify on my phone, and interrupt it with a YouTube stream on my computer, and then restart my phone music. Plus having high arches on my feet. If you are on the fence jump over it and get them!
