I had read this post before coming to NRT yesterday, and I agree they are a little too loud. They look and feel nice, and work great for radio/movies, but the lowest volume that actually comes through is loud for sleeping. -I ended up listening to jazz with the ear plugs and the headphones, in the hopes the plugs would dampen the jazz to a sleepable level, and I guess it worked.
I miss the Hi/Lo switch of the older Bose, but these work and fit better than our Sonys. Unplugging them to just have the NC effect works for sleeping, too.
In a related story, 3 of the channels (Eye on American and 2 movies) did not work for the 13 hour flight. -Bizarre. So much for catching "Cody Banks 2"
