If you like the DT770 and 880, but think they're too flat, you might like the DT990, which has a pronounced V-shaped response. The bass is very fulfilling on them.

Thanks for the advice! I've heard of Campfire before, but never read too much into them. But the reviews of the Vega sounds like it's a good fit for the sound I want. Does anybody have direct comparisons between the Vega and the K10U or SE846?

I have a wide collection of headphones, but the only IEM I have is my trusty Etymotic ER-4S I've had for over 16 years. I still enjoy it once in a while, but I'd like to get a more modern high-end set. My budget is $500 - $1k, but I can stretch that by a couple hundred for something special...
