some impressions a few days after receiving my custom roxannes.
-a bit bigger than my westone es5's but still fine. they seem bigger at the back of the iem, slimmer at the front.
-solid black acyrlic - build quality is excellent!
-cable - thicker and shorter than I was expecting, but my plussound cable is on its way in anycase. It does seem like the wires can get a bit loose near the memory wire though.
-comfort - I noticed a nice difference compare to the es5 with its non-acrylic ear canal. Seems soo easy to insert and get a seal with the rox. Doesn't quite grip as much as the westones do though. Isolation is a bit less, but still good.
-SOUNDSTAGE! Holy cow, this is stunning!! People write about it but nothing can prepare you for its beauty and space around each instrument. Doesn't feel like iems at all...the space is unbelievable. Truely beautiful. It does take a bit of adjustment getting used to this new sensation, but its a very very pleasant adjustment!!!
-Bass is silky smooth, low, full, detailed, and as full as you like with the control. I love bass, and am soo happy with it on the rox. Maybe the best thing about the rox...or is it the soundage...or the sense of realism...
-Treble is certainly all there, shimmers nicely, and seems right for me. No concerns there and Im sure will improve with burn in. (yes I do find a difference personally with burn-in).
-Midrange... stunning again. Perhaps a little bit less fullness than the westone, but amazingly lifelike rendition none the less.
Hope this can be of help - by the way Im pairing with Calyx M, and elekit tu882 desktop tube amp sometimes.
