Conclusion: Iwas disappointed after my first day. the rubber tips are so thin and flexible it's hard to get them into your ears. I have an apple classic Ipod and I messed around for a half hour with the bass, loudness, treble, eq functions and I could not get as good of sound as I could with the factory ones that came with the nano pod. I bass sounded like it was maxed out way sooner than the factory ones.
Summary: So, the other reviews are fairly accurate. I bought (two pairs of them!) a while back and I thought they were good, Senheisser brand made me feel smart. If only I had come here first (or known about head-fi) I could have made a better decision. At $40 they're not worth it at all. If you're willing to drop double that get the RE0s, they will not disappoint.
Summary: Like many other people, I got my cx300's as they were widely available on the high street with not much competition at the time. They are mostly known for their bass which is very abundant. The problem with that much emphasis on bass is the rest of the range suffers. Treble, in particular, suffers quite badly and is drowned out. Add to this very little clarity in the bass which doesn't have great extension anyway and for sound you are soon left wanting.
Summary: Bought these as a cheap iem to use while my customs are being fixed, they sound pretty good for the price, isolate well enough to be bearable on the train, and weren't too expensive.
My problems with them come from the entire design of both the iem's and the product as a whole.
Plastic death packaging is awful, physically getting the phones out of the package was infuriating, rather than a pleasure, even with scissors, and a stanley knife.
Summary: Having been a marketing casualty years ago by the Sennheiser headphone giant having two decent over-ear headphones bought of them, I decided to have these for an MP3 player additionally seeing good reviews about them.
I don't know if eartips of them not fitted well in my ears but the sound was awful!!!
I can't say enough about mids, trebles, basses etc. but overall the sound was harsh to a point that my ears couldn't stand the dreadfull noise of them!!!
Arrived poorly packaged in a DL envelope which was torn ...

Summary: Arrived poorly packaged in a DL envelope which was torn in several places. The ear buds themselves are a quite bit smaller than the originals and therefore don't work very well, especially in regards to fit, comfort and noise cancellation. I won't be using them.
Summary: I got these in around 1400/- but not satisfied when i compare with the other competitive products in the same range. rather opt for JBL. The wiring used is also very down the market type. Better to avoid.
