Pros: Cheap, Light
Cons: fragile, average sound at best
I paid $15 for those headphones, and I did not expect anything great. They aren't as comfortable as you would expect, but it does the job. The sound separation is poor for Sennheiser quality. I own a pair of HD 212 pros, which can be purchase for around $20 now, and I have to say that they are much better in every aspect.
I don't recommend HD 201s.
