Try to post your threads in the correct section, i will PM a mod for you to get it in the Audio and Multimedia section.
Anyway, i will answer. You can't really get better hearphones than what came with your zune for 20 dollars, you should be looking at double or triple that in reality. May i also congratulate you on choosing the Zune 80Gb over a 5th gen Ipod Good move.
I used to have a 5G iPod, but I sold it to get the Zune
And I don't really need high quality earbuds, I was actually happy with the iPod ones. The problem with the Zune ones is that they create a vacuum in my ears and every little rustle of the cord echoes in my ears and gives me a headache.
