They do work however [SEP] I dislike that the buttons are in the back it does not show that on the products and I see that if you are deaf there is no where to put your cochlear implant. The headbands do work I test it out. But not with all my equipment on. So I been sewing little tuck pockets on headbands for the cochlear implant because I am a crafter but if you got no knowledge in sewing and you deaf go on etsy they have what I am talking about they cost more but if you don't know hand sewing that's the way to go.
