I currently use my PC for watching films. Now I have a set of sennheiser PC150 headphones which are now on the blink. I'm thinking of replacing the headset with the sennheiser HD595 (which will be superb for films I guess) set. Is there a type of microphone which is uber sensitive and will clip on to my ear - whilst I have the 595s over the top? Or is there a really good one which will go on my TFT?
