Great in ears
Great pair of phones, I can say that if I ever get a pair of over ear headphones it would probably be from this brand. I have never heard someone say that they don't trust sennheiser in person, and I can now see why.
These are some great headphones, for $100 I wouldn't have bought any other pair; They don't have a perfectly flat sound like some people may prefer, but for my taste in music its great.
Not necessarily a con, but its not worth the time to put the headphones back in the case, I only use the case for traveling; Buttons don't work how they should on HTC 816, but that was to be expected.
