Pros: Comfortable, the sound is balanced
Cons: leaks sound to much
Before you read this you should know that I have only tried them for a couple of minutes and this is my experience of them under those minutes and this is all from my own preferences!
The headphones is overall good and the sound is balanced BUT! They are a little to balanced to fit my preference. As I said the sound is really balanced but the lack that little extra to make me get that feeling of overwhelming pleasure. Most of the reviews that I read through before I tested them said that the headphones was a little more bass heavy which of course made me happy since I like that little overwhelming bass since I listen to rather bass heavy music. I am sure that they are really good for those who listen to classical music but I would not recommend these headphones for those who like bass heavy music. The reason to why I gave it three in rating is of a different matter. When I talked to the employees from Sennheiser they told me that momentum was the newest in sennheisers "on the go headphones" witch I think is wrong. Perhaps it is my head that is to small but I think that they leaked way to much to be a good pair of headphones when you normally travel with the subway.
