Technical question...

I am just starting with Rocket Languages French. Is there a headphone/microphone anyone can recommend?

For a while, I was using the Logitech H540 USB headset, and that worked very well, especially for listening to/isolating pronunciation. But after getting some piercings, I had to stop using over-the-ear type headsets :( so I used earbuds along with my laptop's built-in mic instead of the headset mic, and that wasn't too bad either. I did have to move closer to the mic to be heard though.

for me i use the headphone of my iPod , and for microphone i used the one on the mac its self or u can use ur iPhone headphone if u had one. maybe there are better than this but i guess it just fine for the rocket languages

I prefer a headphone. I personally use a Razer megalodon and it seems to work pretty good. Might be a bit overkill for just rocket languages though.

I have a USB headset that works fairly well. It is the headset that came with a major competitor's language course.
