Fantastic. I ran into a strange situation where I had bought a 4 gig Zune for $129, and a month and a half later Futureshop put the 8 gig on for $100!
Anyway, after really going to bat for me to allow an exchange, the customer service guy told me that I would get back the full $129, and be only charged $100 for the 8 gig. I told him it wasn't right to take advantage like that, and he said, thats how they do things. SO, I went and grabbed the premium earphones to "make up the difference".
Wow. After getting used to the inner ear bud (Kinda felt like MP3 rape at first, I kid you not!), I fell completely in love with this. The stock buds that came with the player are still sealed in the box..these are fantastic earphones.
