@hearingpeg You are correct - not all BTE's have a telecoil. My Starkey Halo does not even though I told my audi that a telecoil was important to me 3 years ago! I am in the process of getting new ones and have researched the major brands. Many times there will be a model without the telecoil but it will have a similar model with all the same bells and whistles but also a telecoil. The only difference in the Model numbers is the letter T at the end. So look for that.
