In-Ear Monitor/Headphone Recommendations

I’m going to be traveling and trying to keep my back pack light. I’m looking for some decent in-ear headphones/monitors. I don’t plan on mixing in them but just to write & sketch out ideas. Is anyone using any headphones they like?

Like so many things, it depends on your budget. I use Campfire Audio Solaris, and Shure se535 with a Topping NX7 dac/amp. The portable amp/dac is important, because I think the built-in headphone jack on my Macbook sounds awful.
