I got my Hearphones a week ago. When they are in my ears and switched on, it is like I am in a barrel or my ears are plugged with water (as in swimming). My own voice is too loud , but if I set the World Volume down enough to offset this effect somewhat, then I can't hear other people very well. I have yet to try these in a loud restaurant, so cannot comment on their effectiveness in noisy situations. A friend with regular hearing aids said his doctor told him that problem was because there is no path for outside sounds to equalize the pressure inside the ear. I will try using the small earbuds - maybe that will allow the pressure equalization. ALSO, the buttons on the inline control are too awkward and poorly placed for practical use. Just trying to find the right button usually pulls the earbud out because the right side cable is so short. So I have to use the iPhone app, which is slow to startup, partly due to the photo of a man displaying for several seconds. In short, not very impressed. Several of the important problems with hearing assisting devices have not been solved by Bose.
