My Shure SE846 is shorting out in my right ear while listening. If I put light pressure in a certain way I can replicate it, if I put more pressure it goes away but it's still intermittent.

Is the problem my Shure SE846 or my ALO silver litz cable? My Andromeda is very durable, I'm on my second pair of se846. I don't think I'm under warranty, and when I had problems in the past it was easier to return and rebuy than to get shure or the dealer to answer my questions.

I can't possibly be the first to complain about a loose MMCX connection. I like my se846 a lot, but I don't want to purchase a new one with an unreliable design.

When searching the forum I came across a broken link about how they fixed it (which I can't read), and some advice where shure offered a 50% discount on replacing the broken set, and about pushing the internal pin off center.

Does anyone have solid advice? Does Shure participate here?

Update: I plugged the OEM 3.5 cable in, and so far it's working ok aside from the sound quality. The ALO Campfire litz sounded much better when it was working fine with SE846.

I took the cable in question and plugged it into my campfire Andromeda and I can't get it to short out. It only shorts out with my Shure.

If it only shorts on one headphone, I'd wager the issue is just a loose connection. The other cable is likely less utilized so the contacts are going to fit tighter. Wear and tear over time gets to them all eventually. As for replacements, I've heard the UE900 cable (~$20?) is a decent cable for most IEMs. I wish you the best of luck sorting this out.

Check for side-to-side wiggle of the connector when installed and how easy it is to turn it. Compare it between the Shure and the CA.

Thanks. This makes me wonder if high end MMCX cables are worth investing in, and which companies will reterminate mmcx fittings.

I've got mixed feelings on "high-end" cables. On one hand, it doesn't make much sense to me for a cable to make much of a difference, but I also have a double helix cable for my LCD-X because I believe it changed the sound a bit. So I'd say some cables are worth investing in, but see if you can try one first if possible (the headphone shop I go to has test cables to try first)
