Vocal Career SUCKS in my opinion. I tried using the headset, and the game kept telling me to speak up -- what?, like shout!!! I'm annoyed already, and I've only played today. Glad I only paid $2.99 from the bin for this!
There is a Microphone which can be used for guitar hero look on Best Buy, EB Games and Game Stops webpages to see if they have them in stock. It should look like a regular mic it plugs into the regular controller just like the headset and it works much better
than the headset. All the headset was meant for was talking to your friends while playing Halo, Call of Duty, or those kind of games not Guitar Hero.
