Excerpt: I purchased these MDR-NC40 Sony Noise-Cancelling Headphones from Radio Shack for only $30 this week.

Summary: I have only owned the earphones for a few weeks, but after a few flights, they have proven to be worth the price. With a moderate price point and semi-compact design, these earphones deliver good performance in spite of not being over-the-ear. They do not feel incredibly sturdy, but the soft case is rigid enough to prevent damage in a bag and I don't plan on wearing them out and about. A solid buy for my needs.
