Headphones controls not working with xperia ray

I have Marshall minor headphones with microphone and control buttons for music. I am using these with my Sony Ericsson Ray but I am unable to use the microphone on the headphones. When I plug the headphones into my phone it comes up with accessory not supported. So I have to use an adaptor/converter but this only allows me to listen to my headphones, not use the controls on them? How can I fix this?
