When you are taking orders or changing stocks in and out for clients the last thing you want to worry about is a static connection that cuts off words, or a horrible headset that doesn’t allow the parties talking to be heard clearly.

In these situations it is mandatory to have professional quality sound to get through the work day. The trith is some headsets are better than others. 

Look for sets like teh Jabra Pro 9470 that is known to have satisfactory reviews from customers and has a great rep for being reliable. Business depends on communication. Make it work for you.
