As an ebay user you might be familiar with the Skype internet telephone calling service.  In order to use the service you need a headset with microphone or a stand alone microphone. When you connect to the service the skype software has a microphone testing program. This allows you to adjust the volume to the right setting. Once you have the microphone set up you can make calls to almost anywhere in the world.  Picking a microphone that does the job is key, look for a microphone with a boom. This will allow you to place the microphone in front of you or a little to the side and you can have a hands free conversation. Always place the microphone a little bit on an angle so that pops and breathing sounds are reduced and your conversation will sound clear.  You can also use your microphone for making Podcasts and leaving voice email message so explore and have some fun with your new computer microphone.
