I would highly suggest the NuForce NE600M ($30). It doesn't have in-line volume controls, but it has the mic and button for pausing/skipping. I don't own this model, but I do own three others from the same company (including the model that this one replaced) and they sound great and the mic is surprisingly decent considering the cost. I can't vouch for how well the self-detangling cord works, since its new to this model, but it does have it.
I can't post links yet, but just search NE600M on amazon, it comes in black, red, and lime. The NE600X ones do not have the mic.
