Microphone

• There's no point to calling one of your Skype contacts if you can't be heard. When looking at headsets, do some research into the performance of your desired model's microphone. Look at how close it rests to your mouth and how adjustable it is. A microphone that is too far away will result in a quiet call, whereas one that is too close is likely to overwhelm your voice with the sound of your breath.
  
  

Headphones

• The environment in which you make your calls will play a key part in determining which headset is best for you. If you will be using Skype at home or in a quiet office, a headset with lightweight, over-the-ear headphones should be sufficient. However, if you will be calling from a location that has a lot of background noise, you will be better off with a pair of larger, noise-canceling headphones.
  
  

Cost

• Though there are many inexpensive headsets of good quality, your equipment will be only as good as what you pay for it. If you are going to be using Skype for business purposes, you may wish to invest in a higher-end piece of equipment to ensure clear connectivity. For at-home users, the quality of your microphone is a matter of personal preference.
  
  

Battery Life

• Pay attention to how long the battery on your new headset will last. If you plan to be using Skype for several hours a day, you will want something with a more robust battery life.
