“First of all I'd like to say the customs and the cable are both insane, the customs look incredible and the linum cable and connector beat the hell out of any other CIEM I've seen around.

“ Ok, I caved and bought 2 pair of these when I needed a mini to regular HDMI cable for a new laptop. They are impressive. I like the black color better than the silver too. One thing I quickly figured out is if you reverse them (R<-->L), the cable exits out the top, and you can then loop it over your ears. It seems to fit better this way. By flipping them...” --Neeky
