I was trying Sennheiser HD201 in Dick Smith and found the Sony DJ Headphones are better, tested by my not-professional ears. I think the MDR-ZX300 has better value, comparing the price and sound quality, but it all depends on what you are looking for.
MDR-V55 link is here.

BTW, Officeworks also has MDR-V55 for $150, but not have MDR-ZX300.
Double the price, no doubt its going to be better ;)
