Query: Great for studying

I just got these headphones to replace a pair of Shure e2cs which I had lost. I am a college student and use them mainly to block out noise in my dorm room in order to study or watch a movie on my laptop, and they work perfectly. I absolutely love the isolation that they provide, and the sound is near-perfect. Be careful, though, that you will be comfortable wearing in-ear headphones. For me, they work perfectly, but many of my friends find them uncomfortable to wear. There is a big jump in sound quality from the e2cs, even though they provide the same amount of isolation. I am very happy with this purchase. MAKE SURE YOU DON'T PAY $300 FOR THEM! These headphones are relatively easy to find for much less if you look in Amazon Marketplace or elsewhere. Enjoy!
