Phonak ITE hearing aid Phonak ITE hearing aid Review

These are digital ITE (In The Ear) hearing aids. The sound changes automatically depending on what situation you located in, i.e.. home, work, restaurant, movies, club, concert, etc... I personally find it annoying because one will change sound and then the other will catch up or sometimes, the other one never does "catch up". I didn't realize that I'd be able to hear the sound go lower or higher.
I like to be able to control the settings myself. There is no on/off switch; you must take out the batteries. And the battery life is 1 week. I've had hearing aids where the battery life has been up to a month or more. This is my 5th pair of hearing aids, and I've never been so disappointed before.
When you put the battery in and put the hearing aid in your ear, you hear the screeching of the hearing aid unless you press the button to the mute option. That I find very annoying. If there was an on/off option, that wouldn't happen. Also, once you turn it back on from the mute option, you hear 4 beeps. Is that really necessary?
