I purchased these for about 10,000 yen 6 months ago. They work great and are very sturdy. Sound quality is just about the best you can get on a single driver. The only thing that I don't like about them is that it takes more time to take them out and put them in compared to normal earbuds, but that is the small price you pay for great noise isolation and sound quality. If this is the price range you're looking at, buy these headphones. They are worth every yen.
