You will be given a definition of a task first, then some input of the task.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

I had 2 problems with the product. First the sound would cut out of one ear unless I played with the connection and second, using the extension caused the sound in my left and right headset piece to reverse (right sound came out of the left ear and vice versa). I have requested a refund and will not reorder if this is normal.
Output:
Negative
