I'm looking into headsets or mic, not sure about the names but it's an adaptor:
 
Examples:

Just want to know if there are any good recommendations, nothing expensive please...

 
Just wondering if there is anything out there and more so, if the links i posted are compatible with the Samsung Galaxy S.
 
I own the DH-C571's, and would like something to replace the extension wire, whilst being useful at the same time!
 
Thanks for your time,
