I already posted this in the Phone subforum, but got no responses. Locked it and now posting it here... Budget is preferably =/< $40. Yes I want them to be IEM. Yes I want a mic. Yes I want noise cancelling and not just noise isolation. This is for plane trips. Nothing annoys me more than when people make a request in a thread, and then people try to argue them out of what they want. So, I want those three specifications at that cost or less. USED IS AN OPTION. I don't care if they're used so long as I can get them by next Friday. Right now, I'm looking at various ones from AKG, Ultimate Ears (all used, as they stopped making their less expensive models after moving to Logitech), & Audio Technica.
