Hello Head-Fi! Firstly, I would like to say that I have been lurking around here for awhile now and recently made a purchase for Shure's SRH840 due to the reviews and criticisms I have read from the boards here. I am loving it, so I would like to say thanks first. Consequently however, I am now looking for an upgrade for my IEM. XD I am coming from the CX300II, which from what I have read, is just an average IEM. I would imagine that many headphones would provide a better audio experience than these IEM, though it probably doesn't help that I do have a SRH840 to compare headphones to now. This is where it got tricky for me, which is why I am making my very first post to ask for some advices. I am quite torn between the Monster Turbine (I would like to give Copper Pro a shot, but that's kinda out of my budget at the moment) and Head-Direct's RE0. I could tell that the people here highly rate RE0 due to its value and its quality. However, my main concern with the RE0 is that I heard it is a very neutral IEM. Might sound slightly strange considering I have the SRH840 as my main pair of cans at the moment, but I purchased the SRH840 for mostly audio work. Thus, neutral was what I was looking for. When I am out in the streets, I prefer something slightly more exciting, which I read in the Multi-IEM reviews is what Turbine offers exactly. Additionally, I also heard questions about RE0's durability and build quality. Is the IEM sturdy for almost everyday usage in the streets? I like to think that I am quite good at taking care of my IEMs, but truth to be told, I have recently gained the habit of storing my main IEM (within its pouch) in my pocket. I also go to the gym with my main IEM, so, whichever IEM I am purchasing will be enduring quite a bit of a treatment (or so I think, it can't be that healthy for a pair of IEM to be sat on regularly!) At the moment, from where I am, I can purchase the Monster Turbine for $139US and the RE0 for $89US. Is the RE0 worth the price gap? If they are as neutral as they are said, would I find myself missing my SRH840 instead? Anyway, you can say that I am looking for something different for my portable usage. I am mostly hoping to buy a good upgrade that could be played directly out of my iPod (6.5G if it matters) and could endure some, maybe, harsh treatments. I am also open to other IEM suggestions, which in this case, I am hoping to keep the budget under $200US. I am not very big on extremely thumping bass, but it is VERY important for me to know that the drums are there clearly. I also like my trebles. In addition to these preferences, I mostly listen to rock, metal, rap, and any genre from the Japanese. Thanks in advance and sorry for the long post!
