I saw this on ebay today. It's the only product like it that i've found. The plugs and guage of the wire look decent, but they may only look good. For all i know the wire under there could be as this as hair. Anyways, I was wondering if anybody has bought this or if it's worth it. I might just buy it to stop using the 3.5mm adapter that is eventually gonna break the jack in my phone.

Some users (myself included) bought a similar cable without the microphone.
Spoiler: yes, the cable inside probably is thin as a hair. Nobody complained yet about quality issues but you have to keep in mind that, the open back nature of those headphones will limit the use of the mic.
