I have a pair of Grado SR-80 headphones. I bought them one wet, rainy evening about eight years ago, when Marianne and I went shopping down on Shattuck in Berkeley. I’ve bought several other pairs of headphones over the years, even tried out Charles’s expensive noise reduction jobbies and nothing comes close. I bought a pair of Sennheiser noise reduction headphones last August, used them and like them very much. I let the old Grado’s fall out of use, but then a while ago all the fiddling around unpacking the Sennheiser’s just got too annoying and I plugged them into Bob the B2 Stealth Walkman, and damn if they didn’t sound good. Need to find a new pair of foam ear pads, but other than that, they’re the best thing I’ve ever heard. If you ever need headphones, start here.
