Task: Sentiment Analysis
Input (English): I bought a new pair of these headphones last night at Best Buy for $49.99 brand new. After listening to them they were very tinny, with no bass. It sounded like the subwoofer had been turned off. There was also noise cancellation (didn't work) on all settings; it wasn't even adjustable. I'm not happy that my money spent here has been scammed out of me. I'd expect more from Sennheiser given their reputation in ear headphones.
Output (English): Bad review
