Authorized Senn dealer Razordogaudio has the IE80 for $349 w/ coupon code RAZORDOG100 http://www.razordogaudio.com/products/sennheiser-ie-80-professional-portable-earphones .
They also have the Momentum with coupon code RAZORDOG50 for $299 http://www.razordogaudio.com/products/sennheiser-momentum-black-closed-design-luxury-headphone
I would jump on it, but honestly even $349 doesn't seem like that great of a deal. I think us US people are kind of getting jobbed on some of these Sennheiser product prices. I know other places have it bad for certain products too, but blah.
