Simple:
Shure SE215
http://www.shure.com/americas/produc...ting-earphones
-Excellent sound quality for price (~$100), far better than bose
-High durability. 2 year warranty.
Detachable cable (cable always goes first)!
-Foam Eartips result in the best passive noise isolation available on the market
-wrap-behind-the-ear style and amazing engineering design result in the best fit you will find that wont come out. Great for workouts
-thickest cable ive ever seen on a earphone
You used to be able to get them at futureshop but I know Long and Mcquade sell them as well
Edit: Note that these Shures, like any good headphone/earphone, take HOURS of listening before you get anywhere near their full frequency response. If took about 50 hours before i got the best out of the shures
