These headphones are medium quality ones from Sennheiser. These are not easy to use for me. Sound qualit is nice compared to its price. Actually I don’t understand why Sennheiser have this kind of headphones, I call them “headphones” but this ones are not headphones nor earphones because it doesnt fit the ear like headphones or earphones do you can hear noise from outside. Sound quality is good but bass is not enough.
+ It is very light, when you wear them you’ll forget that you have headphones on.
+ Active noise block system
+ It has its own bag and box
– When you pack the headphone, its lead makes trouble always
– Compared to other headphones, this one looks weak
