I suspect this has been covered already by certain bloggers, but am too lazy and uninitiated to check. Anyway, this falls within ikka's scope of interest, so 's all good. However, this post is probably not too interesting if you don't follow K-ON or care about headphones, lol.

The AKG K701, a model that's more high-end than your average (both price-wise and, according to reviews I've read, performance-wise), has recently garnered more attention after it was shown to be used by Mio in K-ON episode 5. According to one Taiwanese blogger who wrote about this, its sales ranking on price comparison site kakaku.com astonishingly rose from 41 to 6. Whoa.
...as to be expected, the price has also rose accordingly. Akiba shops have also been spotted promoting it with the Mio connection, calling it 澪ヘッドフィン (Mio Headphone) K701, as this image shows.





This phenomenon has found its way to gigazine, among other news-oriented (?) sites.

Admittedly, I've never had the chance to actually use the K701 - for one thing, it costs about $600 or so in SGD. The specs and manufacturing details are appealing, though. But this piece of news was pretty interesting, not to mention funny. Who's with me in saying that some of the people who bought it wouldn't know the difference in quality between the K701 and a more lower-end pair of cans?
