I use my mobile phone constantly throughout the day for work and need headphones to so I can have both hands free. These headphones are amazing, comfortable, and a great buy.

Ex Output:
positive


Ex Input:
I bought this set but it’s missing the kneaded eraser that was mentioned in the title, description, and pictured. This was primarily the reason I bought this item and I’m pretty pissed actually

Ex Output:
negative


Ex Input:
This is cheap material and it definitely doesn't look like the picture at all. But I guess that's what you get for buying cheap. I would love a refund but Amazon wants me to return this cheap jacket/windbreaker whatever it is, problem is I no longer have it, I throw it to the trash. Shame on you Amazon, why would you let sellers like them offer their products through such a great company.

Ex Output:

negative
