So it's been about a month and half since I first got these. At first, I was pretty surprised by the amount of edge the treble had. It has since seemed to calmed down a bit. The treble is brighter than what I remember from the MEElectronics M-Duo, which I thought had quite energetic treble to begin with. The treble on my RE-400s in comparison now sounds dull. I feel like a more V or U shaped signature is my preference. The bass is so nice and tight. I feel like it's just the perfect amount too. It's not overbearing on the more natural genres of music but still has plenty for electronic music and rap/hip hop. It's rare that I find the bass over done. While the mids are a bit recessed, I feel like the entire presentation doesn't suffer all that much. I've really come to like their sound. Fit was a big issue at first, but after a good bit of trial and error, they're great. I prefer them over the ear, which is weird considering I liked them worn down when I first got them.
I've honestly really really come to like how these sound. I guess they really do need ample burn in. Though I did just get in on the VSD2/AN16 preorder, I would like to get another pair of these to compare their sound to the ones I've burned in. There is a Japanese version of the FX40 with a right angled plug, correct? Anywhere know where I can find a pair? I saw some on Amazon but I'm not a fan of their bright orange color.
