I've replaced the standard headphones with a set of Shure SE525s. I use these on both the phone and on my PC, so changing the wire to one that Shure provides with a microphone and button (which might not work anyway) isn't an option. In a perfect world I'd like something very much like the inline volume control that Shure ship with the earphones, except it to have a pause/play button as well. Here's a picture of it I've found on a google images search. I did go and buy a Nokia AD-54 based on a forum post I saw somewhere. Sadly it doesn't work, not only that but music doesn't sound right through it either. Is anyone aware of any solutions?
