In short, I pwned myself. I bought a Sennheiser PC30 Headset to use with my PowerBook. It turns out that the microphone doesn't work because it uses a standard microphone plug and my PowerBook has a line in jack (which isn't the same thing, as I had previously thought). After doing some searching through their FAQ, the solution they gave me was to either buy their mac one (for $120...I refuse to pay more than $50 for a simple headset), buy a PC USB headset, or buy an iMic universal adapter. The easiest solution for me would be to buy an adapter but the iMic is $40; in other words, way too expensive. Does anyone know a less expensive alternative? If not, can I get some tips on how to return products bought from NewEgg? I heard they are a pain in the butt regarding returns. Can I also get other recommendations for possible alternatives to this headset should I have/manage to return it? I appreciate the help.
