Sandy - According to Rick you should not feel the TransEar 270 vibrate. Hopefully he will pop in here and reply to your post. The vibration is why I am getting a remake. I only hear sounds on volume 3 1/2 to 4, but with that I get alot of vibration and more so with high pitched sound. When the phone rings or with the tone/pitch of certain voices, the TransEar vibrates like crazy. With mine, we are thinking that the processor is being over driven, so a tighter fit should solve the problem. I will get my new one some time this week.
Mine is very comfortable, I acutally forget I have it in. It sounds like you and I both only hear at the higher volume levels. If I were you I would call TransEar and talk with them. Since my audiologist was new to the device, she couldn't help much, but TransEar was able to step in and help her out.
