I find volume on the new smartphones to be lacking no matter which ones I try. Do headphones help? What kind? I wear BTE aides with a telecoil. Your feedback is appreciated.
My DAI cords do seem to help but for me the ability to hear clearly has dropped when using my cell phone- I don't know why. The sound on my PC when using Skype & VRS (vco) and my DAI cord is miles better and louder.
