That is some kind of half-transparent sticker/foil
I had a friend who did this to his Ipod....
He got a sticker with the carbon fiber look and printed the things on the back of it.......
then he stuck it on the Ipod and cut out the holes......
you can get the holes and writing template on the net......
My friend LCD 3 set up :
source : ibasso dx 100
Dac : ibasso db2 balance full mod
amp : alo Rx 3 B
headphone : LCD 3
cable : Stephen Art Endorphin for LCD 3.
Ibasso dx 100 > ibasso db2 use coax cable DIY
Ibasso dB 2 > alo Rx 3 B use balance Hiroshe to balance RSA .
That cable looks....dangerous.
I've had my share of mid-range iem woes recently, evinced by this thread: http://www.head-fi.org/t/625499/what-is-the-general-average-lifespan-of-iems
These are some IE60s I got for £96 to replace my Beyerdynamics:
They sound a bit better and seem to have a more solid construction - I get tired of going back to stores to replace stuff.
