It works. Poor packaging, no box or case, terrible smell.
The cable arrived in a plastic bag which was inside a padded envelope along with a packing slip. The case that was shown in the photos does not appear to be included anymore because mine came in just a plastic bag (not even a box that other reviewers mentioned). I connected it to make sure it works (thankfully it does). Unfortunately, even after leaving it out for a few days, the cable still smells really really really bad so I cannot actually use it yet. This is the second Linsoul cable I have purchased that was like this so I don't think it was just bad luck.
The cable itself is nice and thick and probably will not tangle easily, which is what I was looking for (more for home use). The MMCX connectors are a bit of a tight fit and my earbuds don't swivel unless I make it so be careful when connecting the cable to your IEMs. I have the Linsoul 7N OCC cable, Meze Audio Rai Silver Plated cable, and several Shure wired and bluetooth MMCX cables and none of them have this tight of a fit where I feel nervous about using the cable.
Would not recommend to a friend.
