I'm on my second shell using TransEar. With my first one, I simply did not get enough performance to satisfy me that it was wortk $3K. After about a week, my audiologist tried increasing the gain which resulted in little improvement. After gain was increased I had to reduce the volume to eliminate feedback and the net was no better than I started with. After I reported continued disappointment, my audiologist got on the phone with TransEar to discuss. I'd also reported that I could feel the vibration. Whenthat was reported to TransEar they'd indicated that shouldn't happen and shipped out a slightly larger shell. This one is performing much better but I still feel the vibration. Can anyone give me some feedback on how much vibration you feel and maybe how snug it fits. I noticed that the first one came out of my ear much easier than this one but I wonder if this new one is still too small.
