Which would you buy?
The Phiaton is $144 with shipping, and the ATHCK7 is $110 with shipping.
I'm mainly looking for durability, and since the AT's are made out of titanium, they should be pretty durable. However, according to a Head-fi search, the Phiaton is pretty durable too.
The Phiatons look better to me, but in the end I'm looking for something durable, and I can't decide between the two.
