InEar phones with mic

[Austin10]

Hi,

I just bought a Motorola Atrix and as it happens my old InEar phones (Creative EP 630) just broke. I like those ones but they break too quickly... it was already my second pair.
Now I wondered two things:

• Can I purchase any phones with mic and plug it into the 3.5mm slot and the phone will accept phones and mic?
• Are there mic/phone combos with comparable sound quality two the EP630? If yes, which ones? If not do you have any other recommendations?

Thanks!
