Well, for those who like me read the entire thread there is a mention on page 1 by someone who owned a pair of the Razer|Pro Tone 250 of the Razer|Pro line... a more discreet line of products that are less black and luminous and more general-consumer (as opposed to the hardcore gamers) oriented made by the Razer mouse company we all know. And that is no carcharias, this aforementioned headphone is just this http://www.foster.co.jp/en_products/headphones/388404.html rebranded.
I've been trying hard to find one since then but they are all discontinued. Reviews about it all seem quite stellar, and I've heard here that so is Foster and -tex, haha. MSRP was 49.99$ for the Tone 250, which I would have totally bought being more aware of the facts here in 2007, year of the Google results about the clip-on headphones.
I think we just need to open our mind and eye a little to find out about Foster products around us and in the stores we think we know the products. I loved my JVC clip-on I've lost somewhere, if only I could find the updated version of the 388404 the 429456 http://www.foster.co.jp/en_products/headphones/n429456.html
