... finding even half-decent noise isolating earphones with that kind of budget restriction. Avoid any active noise-cancellers in that price range: they won't work. The best you can expect really is the passive, not-that-great levels of isolation to be found on earphones like the Sennheiser CX300, V-moda bass.freq, Sony EX phones, Apple in-ear phones (not the ones that comes with the iPod), etc. It's certainly better than nothing, but not a patch on phones like the Shures with the Comply tips or the pricier, effective electronic cancellation in the ~$300 area.
Just wondering if anybody had a solid pair of affordable noise canceling earbuds that would be good for long flights. Looks like I'm heading overseas this winter and it's gonna be a loooooong one. Any info would be nice. Something around the ballpark of 40 dollars or less would be great.
