I've been looking for a decent $99 noise-cancelling headphone, but haven't found one I could recommend. The Noise Hush i7 might be it. It obviously resembles a Bose QC-15, and while it doesn't have the QC-15's sound quality or class-leading noise cancellation, it seemed pretty decent in my brief listen. And unlike the QC-15, it works with the NC switched off and when the battery dies.

@TATEAB: It's coming, later this week. I'm pretty excited about the D3020, too!
Speaking of NAD, I'm looking for information on that company's D3020 amplifier and D7050 receiver. Please provide details.
