It is endlessly frustrating to me. Can these be returned? Three changing ports out of four do not work right after unpacking. I’m an 8 and the 8 is a little small. It has to look professional, like it was made for the Polycom versus one that is a work-around where you have to connect it to the desktop phone handset and then to the headset base. Sadly these will not come with it. 50 or something. We’ll use it again for sure. They’re super comfortable and cozy, they keep his feet warm, and they fit really well. Ended up buying a different one at Walmart.
