A simple clip that fits onto the headset provided with a Sony Ericsson Android Phone. This will press down on the mic mute button essentially tunring them into regular headphones that you can use with your laptop etc. Now you don't need to carry extra pairs of headphones!

Note: While this should allow this headset to work with many headset jacks if doesn't work reliably on a Nintendo DS Lite

Print raftless, thread onto earpiece wires just above microphone bulge, slide down wires and press onto top of bulge so that the mic button becomes depressed and remins so when you take your fingers away.
