Hi there. I have just bought a pair of Sennheiser HD 205 headphones to replace my disintegrating Sony MDR-CD570's and am just wondering what everyones opinion is on these. I have tried one on either ear and switched them over and i can't decide which is best. The Sony's seem a little more open and transparent but the Senheiser's bass is a lot better but the midrange is too soft, and they are very tight to the point they give me a headache. What do people think of the latest Sony headphones, particularly the replacement to the MDR-CD570's, and how do they compare to the equivelently priced Sennheiser's, bearing in mind my old Sony's cost £60 and the 205's cost £29. I bought the 205's because they were cheap and they have a good reputation, but i am starting to think i should have looked around a bit more and spent a bit more money. I don't really want to spend over £50 though as i am SUPPOSED to be saving to go on holiday in Jan. Any thoughts and opinions would be appreciated, Cheers, Andy. P.S. Do headphones need running in too? Maybe thats why i am not blown away by the 205's?
