Instructions: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: I bought these to help with what I've read, to get the Jawbone to fit better. These ear pieces were hard to get into the ear no matter what size I tried. For a wireless earpiece you want to be able to get it on and off your ear quick if you need to, and these prevent you from doing so.
Output:
Negative
