Headphone tip came off headphone adapter and is stuck inside kemper

Probably the safest thing to do is take off the cover and use a small piece of wood to push it back out. Provided it's not totally enclosed on the back end.

As Larry said taking the cover off is probably easiest and safest way. However, if this isn’t an option a few other tricks can be used.

One option is to dab a little super glue on the end of a dowel or drill bit and push this into the socket to stick to the tip and pull it out.

Another option is to drill it out with a reverse thread drill bit (screw remover).

insert another plug and you might be able to push the broken tip through. it would fall out into the chassis assuming the back end of the jack is not restricted so power off and unplugged

don't force it, if the back end is open it shouldn't require any extra force. of course remove broken tip before using

just an idea-

Maybe a long-ish slim self-tapping screw that is narrow enough to grip the hole inside the tip that has become detached.

The risk of superglue (if used wrongly) is that it could seep into the device and create other issues.

I’d be shocked if the jack used wasn’t enclosed similar to this. Nowhere to go:

Can you see what’s left in the jack? Obviously the tip…but is it flat, or is there a lead of some sort sticking out?

A set of needle nose pliers like these might bea able to grab it.

Some time ago I had the same issue but with a diferent device. I used a Screw to get it out.

Use some epoxy putty on the tip of a small wooden or plastic round rod (e.g. a pencil or pen refill)

and push it into the socket up to the tip that is inside. Press it lightly and let it harden. then withdraw it.

You can also try toy dough first.
