Summary: I am using it for my Samsung Galaxy S3 phone, the volume control (up and down arrows) is not working. This headphone is big, not convenient to carry for me. The sound has more bass which muffles the pure tone. The sound quality is not better comparing to my original Samsung S3 headphone, but the price is much more expensive.
Summary: After using these for a week, the best I can say is that these headphones are okay. They fit comfortably in the ear, and rarely fall out when you're running or working out. The sound quality is good, but for the price, I expected better. The bass isn't as heavy as I thought they would be. The highs and lows were good, but nothing spectacular. For a pair of Monster headphones, they really fell short of my expectations.
