On another note, I had been using the reds for a while after gnarlsagan recommended them (and preferred them to greens). After our group buy I tried the oranges. While I think they have almost perfect bass, the treble was just a bit more uneven. I used them for a while and although I really liked them, I started to want the treble back a bit more. I switched back to greens and found, as I always have, that they are just a bit too peaky in certain ways. Used them for a while anyway to see if i'd get used to them. Nope.
So, I switched back to reds. I wanted to try the orange again, but didn't have a pair. Loved the reds, but wanted that little extra bass again. I found a single orange filter and then realized that mouser had actually missed the single orange filter that was to be its companion. So they sent me the single orange and I popped them back in. Used them for a few days, loved the bass as I had remembered. However, I found that the treble was just a bit off. I'm not sure if it's the difference in filter variation or just that I was so enamoured with the bass I didn't care the first time. Anyhow, the middle region of the treble was ever so slightly soft in parts and the upper register of the treble had an ever so slight peak. Not really raspy, but bright really high up but no in the main treble region. This gave it a sort of softness with a rasp for lack of better words.
So, I switched back to reds. I've said it before and I'll say it again. Reds the new color. Red is it.
I'm a redder for life. ;) lmao. But seriously. The bass is slightly improved from the greens. The very slight green treble peakiness is reduced nicely and the overall signature retains the incredible er4s quality. Tri flange tips, red filters, er4s. Beautiful.
