I recently purchases some wireless headphones with a microphone. My intent was to use them for creating elearing courses. I thought the wireless option was cool. After shelling out about $130, I got them home and found that the microphone had way too much static for producing elearning. It might have been Ok for playing games, but not something that needs to be polished.
I was very happy that I picked them up at a major retailer and just returned them the next day. I might have been able to return them to an online discounter, but would have been out shipping at the very least.
