Active Noise-Cancelling In-Ear
Great, compact product at a reasonable price. Doesn't block some sounds, but does significantly reduce outside sounds.

We bought these for a recent trip to Europe and they did a fine job of reducing the airplane noise to a much lower level. They even reduced some overly loud conversations when we were trying to get some sleep on the plane. With the adapter for plugging into the airplane audio jacks, I was amazed to be able to clearly hear the audio on the movies for the 1st time in many years. I kept them on for the entire 9 hour flight from Europe to Atlanta, even when not listening to audio. They may not be the best device of their kind but for the money we were very glad we bought them. Definitely recommend them.

I am very pleased with these earphones. The frequency response is excellent and the noise reduction works very well with my iPod. These are great for eliminating jet engine noise and they are very comfortable to wear for extended periods.
