CX200 vs. Klipsch Image S4

I don't quite understand the idea of comparing a $15 IEM to an $74 one. Since you are not used to using IEMs, perhaps you should start with the Cx200 for $15. Some people can't stand having something in the ear. I have the CX300. It is okay, but not great. The CX200 is probably quite similar. $15 is a great price. Are you sure it is real? There are so many fake Sennheiser earphones. Is it from a trustworthy high volume dealer? How can you get an S4 for $40? Do you have a friend in the business?  Are these used? If they are used, make sure they are real and work okay. I don't like the idea of buying used IEMs.

The S4 are great if you can get them for 40$. Keep in mind that they are warm and bass-heavy though
