I am using them to play music on whilst on the bicycle and whilst at work, they perform very well and have fantastic quality, really good purchase!

Top Notch.....best of the best.....u can't go wrong on these.....another masterpiece from Sennheiser!

The sound quality is neat, but the base part isn't enough. Personally, I feel like I'm lacking compared to Beats by Dre. It's just a personal feeling :)

I bought these on sale some years ago, something of an impulse purchase when the price was good! My area of use is mainly at home, and of course the noise reduction does not come to its fullest. But in terms of sound quality I am very satisfied!
