Ok..here is my update. I've had the BP110 (Power) for almost 4 weeks on a trial basis. It's been "tweaked" once, after about 2 weeks. I'm going back Thursday for another adjustment before I decide if I want to make the switch. For me, the sound quality has been better than the BP 100/3. Word discrimination is better and the volume/power is better. I do have some feedback and whistling, but not as badly as I had with the BP 100/3. I get a low whistling sound, almost like rubbing your finger around the rim of a crystal glass. It's intermittent and has actually improved over the last few weeks. I've worn it on an airplane, in noisy restaurants and in quiet environments. I'm impressed. One more go around with some adjustments should bring me to my final decision. The sound is very crisp. The audiologist also changed my music setting to an audio input setting. When on that setting, the microphone is off, so it is not picking up surrounding noise (like an airplane engine). So, if not attached to the audio adaptor, it's pretty much like having it turned off all together. However, I found that that even though I could hear more clearly in the audio input program than the music program with my ipod attached, it still sounded very quiet. When I put an earplug in my good ear, the sound came to life and I heard the music in my head, just like I do in a totally quiet environment. My audiologist has not told anyone at UCSD that she got the demo Power model in for trial, because she wanted me to have as long with it as I need. I do think my decision will be to make the switch, but I will let you know for sure in another 10 days or so. What a blessing to be able to try this for such a long time. It really helps in the decision making process. I will be moving to LA soon, but will continue to go to UCSD in San Diego for all my audiology appointments. Though when I was first diagnosed it was at HEI, I now have this wonderful audiologist at UCSD and they do not charge me for appointments to adjust my BAHA processor. I pay for my yearly audiogram or if I see the doctor. Or, I pay the copay and my insurance pays the rest. I've established this great relationship there and am not ready to make a change.
