Buddy of mine is looking for a pair of Sennheiser HD 202 headphones. I found them on prophecy.co.za, havetohave.co.za and expansys.co.za. What are the differences between Sennheiser HD 202 MK II Professional Headphone (Black) and Sennheiser HD 202 Headphone? The former is a newer model, but costs less. Are they worth the buy? He's not an audiophile. He just wants something that will provide good quality.
