When you work from home in a call center phone job the number one thing that you will need is a really good headset. Plantronics is the most recommended headset by telecommuting companies and there are some good reasons why.
Plantronics is the leading manufacture of headsets, both corded and cordless. They have a superior quality for sound and come with noise canceling microphones which helps to screen out background noises. The wide selection of designs to choose from are over the head, behind the head and over the ear. They are lightweight and comfortable enough to wear all day.
They may be a bit more expensive than other brands, but the quality is worth the price. For the lowest pricing I would look for them on the internet at places like Amazon or Ebay.
