I agree.
Add:
x Due to the deep position of the speaker, there is less occlusion effect
because there is less exposed canal wall in the space between the seal and
the eardrum.
x There are no sound tube resonance issues since there is no sound tube..
x Actual sound pressure at the eardrum should be a lot easier to predict
making the initial pre-adjustment of a hearing aid more likely to be in the
ball park.
x Quicker and less costly to repair speaker (receiver).
I thought Sebotek had this patented (?).
The Vivatone appears to have 4 bands and 4 channels (I think the Sebotek
does also). I wonder if they will have a 16 channel version also.
