WTB: Sennheiser MX 760 for 30 GBP or 50 USD

[RMSMajestic]

Not sure if it's a good idea to look for a sennheiser earphone here.
Was looking for a earphone for my MW600 bluetooth headphones. But got desperate after searching through taobao.
Hope some one here has one for spare, offering 30GBP or 50 USD covering postage to China, which I believe is quite decent for an old earphone.

Also if any1 has Sennheiser MX 880 plz let me know
