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 bought this based on the reviews that said that these will fit the jawbone 2 bluetooth headset. They did not fit very well and were very loose. I use the small size and they did not fit very well. The medium and large size do not fit my ear canal. Too bad as I need an in-ear bluetooth to hear well. I guess I will have to look for something else.
Output:
Negative
