I am new to the forums and have little experience describing sound that I hear as well as sound that I want, so I won't be able to be as precise in the descriptions of these things as may be ideal. I do not consider myself an audiophile, but I am (apparently) very picky when it comes to the sound I like to hear from my headphones and earphones.
My story: I went looking for a nice IEM to use while exercising, and settled on the RE0s due to the fact that they are very well reviewed on here, and have a neutral sound signature. Having almost no experience with hi-fi headphones/IEMs other than my HD555s (modded into 595s), the only thing I really knew about my sound preferences was that I was probably not a basshead and I would probably appreciate a less "bass-centric" signature, so the RE0s it was.
The RE0s turned out to be a excellent fit for me. The only thing I felt could be improved was the bass. A tad bit more and these would have sounded near perfect to my inexperienced ears. Regardless, I was very happy with my purchase until the left side stopped working altogether. Reading through the forums a bit more, I learned this was a very common problem. I decided I wanted to purchase a new IEM altogether, partially because I wanted IEMs that last for longer than a week and partially because I seem to have been bitten by the high end audio bug.
I then purchased the Nuforce NE-700X, which I did just to make sure that I preferred a less bassy earphone. It has quite a bit more bass than I would like, confirming my suspicions. I definitely prefer the clarity and highs of the RE0 to the amount of bass put out by these earphones.
I primarily listen to alternative rock/pop, and trance/electronic music of all kinds.
I am looking for suggestions on what to purchase. My budget is now ~$250. I have narrowed it down to a couple of IEMs: the RE-252 and the CK10. I am thinking the RE-252's would be a great IEM for me, but I am concerned about the fit and comfort of them. I am also considering the CK10, but I'm wondering how the bass compares to the RE0 and the RE-252. Of course, other suggestions are welcome. Judging solely by the description of their sound in reviews, these seem to be what I am looking for.
I am not sure if I have given enough information to make it easy to give a definite recommendation of anything, so feel free to ask as many questions as necessary.
