The HD202s were the budget range aimed at DJs on introduction, hence the extra bass. Being into dance music I loved these so much, that I'm on my second set after the first wore out. The cable is nice and long at 3m which is great for the home but that's why they're supplied with a wind-around cable tidy if you choose to take them out - that's how the first set broke. Now they are my home headphones and for going out I have Sennheiser's PX200s for updated noise-cancelling.
In the years since the HD202s were released Goldring have fought back hard with a closed-back range of their own including the DR50 - since these headphones have sadly gone up in price, the Goldrings - or Sennheiser's own HD201s - have more balance to their bass, so if you're plugging these alternatives into powered devices like computer speakers/soundcards or hi-fi separate CD players, you'll get a better balance to the bass than the booming wham-bam of the HD202s (again, dance, metal and hip-hop fans might not care about too much bass, it depends on your music taste).
If you want to be a DJ the HD 202s remain an excellent budget pair to buy whilst you're learning at home, though, compared to the average price of rival brands starting at double this price.
*Since reviewing these headphones I have bought a third set, and the only difference I have found with the "MK II" branding is the packaging which is now all black instead of blue grey and yellow. All the physical specification remains the same as before.
