The colour isn't for everyone, which I assume is partly the reason for the low price. This specific model (Quincy Jones signature) went out of production a couple of years ago.
I'm a bit suspicious of the price, but from what research I've done, there isn't really a market for counterfeit Q701's. I paid with PayPal just to be sure.
Despite being 62 ohms 105 SPL/V, these are apparently fairly difficult to properly drive. Amp required.
You'll probably benefit from using a dedicated amp of sorts, rather than that output.
