Feedback on my white Klipsch image S4i, Amazing sound quality and they have Oval buds so seal in the ear much better, you cant hear anything anyone is saying. also i noticed they are more powerful/require less volume than most headphones, and the controls work flawlessly. Only bad point - is proprietary connector wont work with pc because of extra pin for mic/controls! Now i've just got to educate people on the fact that they are a known brand!
I highly recommend Comply foam eartips. You can order them online for almost any in ear headphone. They have such amazing sound isolation you wont be able to hear anything with them on. I personally have the on my Ultimate Ears triplefi 10vi. The headphones cost an arm and a leg but they have excelent sound quality since it balances sound on 3 speakers for each ear. Its one of the few headphones that has removable cables making them virtually impossible to break.
