Headphone Recommendation

Hey guys, I need some help deciding which of these phones is the best choice for me concerning its comfortableness, sound quality, durability and cost-benefit:

- Sennheiser CX300 (U$50,00)
- JBL Reference 220 (U$60,00)
- XtremeMac FS1 (U$50,00)
- Sony MDR-EX85LP (U$50,00)

I've never owned any headphone that costed more than U$30, so I'll probably be amazed with any one of these earbuds. Since I live in Brazil, I don't have the oppurtunity to try any pair out and therefore your opinions will basically make my mind. I will have to buy the earbuds from BHPhotoVideo so the prices are the ones listed above.

Thanks in advance,
Lokolos.

The CX300 will give you the best performance/price. They are a little bass heavy, but sound decent overall.

Also, check on eBay for the CX300. I was able to get a pair for $15 shipped. Sennheiser is releasing their new models and people are trying to get rid of old stock.
