This is pleading post to anyone who can make a difference......

I've been using the amazing Sony MDR-ED21LP earphones as in-ear monitors for over 10 years and my last pair has just died. 

I have tried countless other types/makes and nothing under about £300 comes close to the sound quality and the wearing comfort I am a musician and singer, and although some earbud types sound OK, they are awful for singing; because they are completely sealed it's like singing with your fingers in your ears.

If anyone knows of anywhere to get some of these earphones I would be eternally grateful.

Yours in desperation,

Andy
