Task: Sentiment Analysis
Input (English): This worked well for about 4 months. I have only had to re-charge it twice... but now the charging light goes out every time they are charged. Bummer, and disappointing. If this unit would actually hold a charge, I'd give them 5 stars, as they seem like great headphones. But given that you can't simply put new headphones on these when they need recharging, not really worthwhile. They do still sound good, and work just fine if their ability to be charged is worth more than that.
Output (English): Bad review
