I know a engineer who works in noise monitoring. He recommened the alpine musicsafe pro eartips to me - he says that next to the really expensive custom one these are the best / cheapest he has seen. ( he is an aberdonian afterall) They are about 15.00 with 3 levels of attenuation and don't strip out all the high end - a good all rounder and reasonably priced. I sing so need to be able to hear myself too and my ears are really sensitve...i got mine off ebay
