For those of you that are still interested in obtaining the Sony MDR NC-10 earbud noise-canceling headphones, they can be had for 11,800 yen, or about US$100 at current forex, at Narita. I was in the duty free Luck Audio Shop in terminal 1 near the RCC (the single-level one) the other week, and grabbed four off the rack for give-aways. They are in the standard blister packs, and I have never seen them cheaper. I will be traveling through NRT again in a few days, and plan to get another batch.
