I have mild hearing loss and tried the top of the line Phonak behind the ear receiver in canal hearing aids and did not like the tin can sound when listening to music. I settled for Resound but still don't listen to music with them. Streaming Bluetooth, my $100 ear buds are much better for music than the $6800 hearing aids! I found the open ear plugs to be more natural as they let in sound in addition to what the speaker provides.
It is not surprising to me that these fly weight devices can't come close to producing natural sound as they are primarily designed to improve speech recognition and while they do that fairly well the sound is to me artificial and un-analog, but in a noisy restaurant I am fine with that as I just want to follow the conversation. How sophisticated can the DAC inside these tiny things be. They are using a digital amplifier- no class A here. So it is no surprise that music sounds unnatural. I will agree that there is an emphasis on high frequencies and when I use the hearing aids I hear a lot more high frequency than without, but it is digititis on steroids.
I suppose that as my hearing gets worse I may need to use hearing aids to make up for the loss.
I would like to hear from anyone that is using the ASI 3DME as to the tone of the sound.
