Example Input: Do not replace your Bose headphones. Get these replacement pieces, throw the stock ones away. These will make your headphones sound the way you hoped they’d sound when you got them. I went for a 20 mile bike ride with them stock and when I got home I checked the mail. My replacement (nibs?) were delivered. I put the new ones on and threw out the old ones. The sound is incredible. Get them. Even if you aren’t sick of the stock nibs. Get these. You won’t be sorry.
Example Output: positive

Example Input: We have ghosts, a wedding to plan complete with crazy wedding planners, murders that seem unexplainable. A thoroughly interesting story interwoven with humor and suspense. I will be following this series.
Example Output:
positive
