Upgrading from CKS70? (No IE8, detailed why inside).

I'm looking to upgrade from a pair of CKS70 that I've been using for almost a year. I like the soundstage, sound signature and the amount of bass, but I would think there would be something with better clarity. I mostly listen to Rock/Acoustic Rock, but pretty much listen to everything but country. I have a pair of Eterna's, which I actually prefer sound-wise, but I found that I don't like the over the ear style IEM's, as I've started growing out my hair a little bit, and it's a bit of a hassle to put them in and take them out. I mostly listen to music on my computer through an X-Fi Creative USB sound card, and a Zune HD. My budget is around 200 dollars, give and take 50 dollars if it's really worth it.

The reason I won't buy the IE8 is that I actually have a pair...that are broken. The customer support from Sennheiser completely ignored my e-mails, and I was never able to get them fixed/replaced. I'd rather not have to deal with that again, especially how much I had paid for them and how long they lasted (6 months), even while babying them.

I've searched through countless threads, but trying to catch up in the headphone world after almost a year layoff is a daunting task, so any help would be appreciated.

Thanks for the response. I should say, I apparently have very large ears, as something like the CKS70 fits perfectly, and I find them incredibly comfortable. I am curious if the Radius DDM would fit the same.

After reading a bunch more reviews, I don't think I can pull the trigger on the DDM's, the fit scares me a bit, and after struggling with the fit of the Custom 3's, I really don't want to deal with that again. I appreciate the suggestions, but I'm now contemplating something like the HJE900 or Turbine Gold's. Or if the the CK10's ever dropped to $200...
