Headset microphones 

Advantages

• They give the best quality recording, especially for voice recognition software.

• The microphone is positioned close to the mouth.

• They come with headphones, so if computer is being used in the lounge at home, it may not disturb other people in the family.

Disadvantages

• They tend to be bulky and if stored in laptop bags, the leads will forever be getting tangled!

• They can be awkward to put on with one hand.
