As far as I know, the tf10 is hard/impossible to find in brick and mortar stores.
From the tone of your thread it seems as though you're from outside the US, visiting New York for travel purposes and taking advantage of the lower local price versus the import price. There are a few local retailer that might carry the earphones you are searching for.
B&H audio would probably have been your BEST option, but they're closed for some Jewish holiday or something until October 19th
You might want to also try J&R or PC Richard and Son.
There are plenty of Best Buys in New York, but they carry mostly consumer products. They might have something like an IE7/8 though.
And if you want to get some cool import only Japanese headphones, check out AC Gears, the audiocubes.com brick and mortar store near NYU. They have a bunch of headphones on the wall you can try out. I bought my sq5, and sj55 there.
edit: and if you want noise isolation, the best you can get as far as I'm concerned are Etymotic. ER4 and the cheaper HF2/3/5.
