I have bought both fake and genuine Sony DJ Headphones and have created this guide to help distinguish between both.

Fakes: Came in DJ box, all information was in Chinese.

Weight
Genuine: Feel heavier and built better. Weight 11.3 oz without cord
Fakes: Built very similar but slightly lighter. Weight 9.7 oz without cord

First Glance
Genuine: Have "Sony" in gray on top of headband. Perfectly aligned and centered text.
Fakes: No "Sony"  Some newer fakes have the "Sony" on headband, but are crudely printed on with small splotches.


Cord
Genuine: Coiled part is Approx. 18" long and rubber is flat black made of a high quality rubber.
Fakes: Coiled part is significantly shorter and over all cord length is shorter.  Rubber is shinny.


Plug
Genuine: Says "Sony" on side and has knotchings and a high quality flex cord.  Input is of shinny high grade copper, 2 green lines, and a screwable adapter.  
Fakes: No "Sony" logo. No Screwable Adapter. Cheap feeling head and cord.  Some newer counterfits have screwable head, but have black lines and inputs that are not as shinny.


Cups
Genuine: Centered and aligned text says "Sony Dynamic Stereo Headphones MDR-V700" Sony logo should be 3d with a high quality sliver text.
Fake: Text is actually aligned well says "Sony Dynamic Stereo Headphones MDR-Z700" Sony logo is painted on and chips on easy.


Padding
Genuine: Padding is of very soft leather and not shinny.  There are no imperfections and look very consistent.
Fakes: Padding is shinny and plastic feeling.  Around edges are lumps and small imperfections.
 

Headband
Genuine: Inside of head band has "CE" logo and a "Made in China" logo
Fakes: No "CE" logo. Surprisingly NO "Made in china" logo... LIARS!


Sound Quality
Genuine: Crank up the deep bass and notice high and low levels.  Should should crisp and clear no matter and what volume. Has just that little extra edge on the fakes.
Fakes: Sound quality is surprising very similar.  Only noticeable when start to turn up the sound.

Life Span
Genuine: Should last you a while.  First part to go is the swivel part.
Fakes: Mine just died in the right ear after 1+ year of heavy use.

Buying on Ebay
Pictures: If the seller does not have multiple images of product. Don't buy! Ask to see detailed photos of item. Stay away from sellers that use stock photo.
Price: If the seller has buy it now for more than half off the best online retailer, you know somethings up.
Rating: Check to see if seller has sold the headphones/ audio products before and what his feedback is. Stay away from new buyers/ 0 feedback.
Location: If your from Asia, thats a pretty good indication that the product may be a counterfeit.
Response: Ask the seller about the authenicity.  If you get no response, or response is a jumble of "translator" English, thats a good indication of a sure knock-off too.

Conclusion
If your looking for a sweet pair of headphones to impress your friends, try your luck on Ebay. Might end up with a fake, might not. If your spending more than $30 your getting ripped off.
If you don't mind spending $30 - $40 more for a great pair of headphones then look for a authorized online retailer. Don't pay more than $90. Look around major online retailers.

Due to an ever changing counterfeit market place, knockoffs are becoming harder and harder to tell apart. Hopefully this will give you some insight in purchasing your headphones. Shop Smart:
