Everyone with tinutus should consider the above plugs if they don't use some already - especially seeing how cheap they are.
The ones I linked to above just attenuate the sound but leave the balance alone - at the loud concert I mention above I could follow the conversation of the guy I went with who was standing next to me behind the mixing desk - possibly easier than without the plugs as they cut the volumne of his raised voice. The music was also correctly balanced.
The plugs above have a triple flange earpiece just like on normal etymotic iem phones. They can feel hard to start with - but you get used to it. You might be able to retrofit some of the other types, like the soft silicon ones that Shure do, but I think you might struggle with the foam ones.
The triple flange bit fits into a clear plastic tube which folds back on itself so the sound has to enter at the bit closest to the ear and then travel back out towards the end of the clear plastic tube and then back round on itself before travelling down the central pipe that feeds into the triple flange and your ear.
At the point of the fold back there is an angled cut which probably helps keep the sound balance.
Anyway - highly recommended - I wear them if I go to a concert, cut the grass, trim the hedge, go to wimbledon, etc. Not to sleep through as they stick out a little.
) in my 'bad' ear. All I hear on one side of my head is the high pitched whine. I am soooo looking forward to this healing so I can get on with ignoring it.
