Have to say I am a fan of the Shure E2C. I have tried a variety of different brands and types and keep coming back to them. I use them both for actually listening to music/videos, and for hearing protection when I end up sitting in the rear section of a DC-9 or an MD-80. I actually took a decible meter on one flight and found that the window seats near the engines produce upwards of 100dB at take off. (Which by the way exceeds the OSHA limits for 8 hour exposure). The reading dropped significantly after take off. However, I like my hearing and don't want to take the chance. The other thing I really like about them is that they are compact, unpowered and lightweight. No replacing batties or problems using them on the airplane at anytime.
