Got mine, used it for a good 2 hour. Just emailed them back to see if I can return it!
I used this with my Shure SE846 IEMs. Don't get me wrong. the cable is super super thin. Just like others have said, I expected a thin cable, but not fishing line thin. It's so thin that it feels like it will break if you apply just a tiny bit of pull on it.
However, I am not sure how nobody noticed this, but the sound quality does not even compare to the stock Shure cable. Also you get louder volume out of the stock cable than with the Linum BaX. I noticed with the BaX I had to turn the volume up about 20% more just to get the same sound level as the Shure stock cable. Also the bass is punchier with the stock cable.
Another thing is that it is too short. If I put the little neck slider all the way down, it sits right under my chin. That's of course with the cable looped around my ears.
Lastly, the connectors are not as tight as the stock cable. They would disconnect with the lightest pull on the cable.
For all of these reasons, and mainly for the fact that you get more Bass and louder volume with the stock cable. I decided that this cable is a no go for me. Hopefully they will reply to my email and let me return it back.
