I flew to San Antonio yesterday, and it was the first time I could really try out my Entymonic 4P earphones. They rock.
As soon as the flight attendant said it was okay, I pulled out the laptop, stuck in “Lord of the Rings” and put on the 4Ps. These are “in the ear” headphones that also act as really nice earplugs. You can only feel the plane, not hear it, and you get great sound.
The thing I liked best was that I seemed to arrive less fatigued than usual. I never realized how draining simply sitting in a noisy cabin could be.
