SkullCandy earbuds from the Shack. Cost 25$, stereo/mono selective, soft rubber insulators, ears don't sweat, and my 'tector only has 3 tone range so I can hear low/mid/high even in a hurricane. The ONLY bad thing I have to say is the cord is a bit short, I've pulled them out of my ears a couple times standing up quickly without grabbing the QDII off the ground. Other than that, I just can't justify spending more on my headphones than I did on my machine (at this stage in my detecting career, as it were, anyway). Also, several of the places around town that I frequent are in, er, questionable, neighborhoods; so I like to keep one ear IN the ground, and one ear ON the ground.
