Found this on the LogitechShop eBay profile. They are currently $349 on the LogitechShop website and rrp for $499.95
These headphones are highly rated. I've been tempted to get some before at a higher price, but at this price I'll probably bite.
Here is a 288 page thread on the audiophile forum Head-Fi, talking and raving about the Triple-Fi 10's:

Edit: Syntax.
Great earphones…although they are big compared to Shure and Westone. The fit might not be for everyone. Swapping the L and R can help (which I did) or they stick out a little bit.
I had these reshelled into customs with an added mid driver in each side.
They're usually ~$200 on US sites but you have to worry about shipping so +ve from me for price and local shipping and warranty.
