I have both a Transear and a BAHA (not in use simultaneously). I first had the Transear, but couldn't seem to get enough out of it without interference which would stop if I pressed the Transear in with my finger. However, the noise would come back almost as soon as I released the pressure. I decided to get the BAHA Intenso and have been very happy with it. However, I notice more interference when talking on the phone with my good ear than I had with the Transear. I think it is just a matter of picking up more of the sound on the bad side and sending it to the left where the phone conversation is going on. I have turned the BAHA down during phone conversations. I have never tried a phone conversation with my bad right ear. I actually got used to talking on the phone with the left ear years ago (even though hearing in the right ear was good then), so that I could write or do other things with my right hand.
