with a price like this , one can not really expect to have excellent quality headphone or comfortable ear pad , but Sennheiser prove this wrong . First of all , the head strap be on top of you head and not behind . this allow you to lean back in a chair or lie down while listen to music which be something I enjoy . the ear pad enclose you ear in a way that no sound escape and it produce bass sound that no normal speaker can make . these be indeed bulkier than earbud , but be well worth the weight . actually , the weight of these be pretty light compare to most other ear enclose headphone which make they great for almost anything . these probably be not the best for run with -lrb- however I find it pointless to run while listen to music because a car might hit you -rrb- , but if you do happen to run with they , they will stay on you head . these be not you normal flimsy 8 $ pair , but for the cost of what they be , the stability and quality sound be more than well worth the bargain . I use these mainly for my desktop computer in which I use Winamp , fl Studio , Audacity , Skype , Windows Live Messenger , web browsing , and various game . I have never worn anything better . there be only one small flaw that do not really matter , but after a lot of wear , the headphone will take shape and will not compress onto you head as much as they have when you first buy they . lastly , a comfortable length of cord come with this great pair of headphone along with a connector for a amp . all I can say be that there be never be a day where I do not want they .
