Amazon has this Sennheiser HD-280 Traditional Closed Dynamic Collapsible Headphones for $69.99 - $10 rebate (p1, p2) = $60 with free shipping. (Thanks John) [PriceSearch]

上次错过了HD497，不过这个贵了一点，不知道该不该买！
随便问一下，HD497和这个比哪个好？

for some suggestion. As I search on the web, the
AKG K240M should be the most valuable one for less than $100, but "K240M阻抗竟然高达600欧，使得许多品质一般的耳放难以良好驱动".
