Task: Sentiment Analysis
Input (English): I bought a pair of these at first and one has stopped working just after the return day. They sound great while they work but if you want headphones that will last you buy something else. Also tried to get in touch with customer service twice for this issue, only got an answering machine most times. Not worth trying since they were never able to send me another headset to make it right. I'm done returning them. Amazon took care of them quickly so I give them five stars.
Output (English): Bad review
