I was surprised too. I'd heard some people going absolutely ga-ga over their Porta Pro's, but I couldn't find them anywhere I shop on-line. They're probably the best headphones you can buy under $30 at a brick n mortar store.
my friend has two pairs of those, in his backpack and in his house. theyre pretty good for the price, but if you want some REALLY good sounding headphones, like good lord these sound good, AKG or Sennheiser. The AKG 240m's are about $70 and theyre 600homs, cant blow em. the Sennheisers; cant really mess up when buying those, durable great sound and they look cool. you could chuck them across your room and sit on them and they wont break.
