The Skullcandy Proletariat NC ($129.95 direct) is a pair of full-size noise-canceling headphones that fold up into a nice, small package for traveling. They also come with Skullcandy's Link system, which is basically a Y-cable that integrates a microphone, in-line volume control, and a switching button so you can use the headphones with your cell phone. Although these comfortably snug headphones sound very good and provide effective noise cancellation, the cell-phone features are a crapshoot. The function button on the Link module works differently with different phones. Also, I'm just not convinced that I want to tie my phone and MP3 player together with a cable.
