If I want to skip to the next song or go to a previous, it'd become a hassle to put my hand in my pocket when I could double-click a button next to my chin... No digging, quicker, and simpler. Even further, if I get a phone call, I don't want to be unplugging my headphones and plugging in a headset, taking off my headphoens, putting on the headset and taking the call. Then taking off my headset, then putting back my headphoens, and putting the device back on play. Same process to make a call. It's a hassle and it's really unneeded. There is a reason why the remote and mic is popular.
