Headphone jack goes in hard..

I feel kinda silly asking this question but I don't really know where I would ask it other than in this forum.

I have a pair of OneOdio headphones that I like wearing and listening to music while I'm browsing the Internet.
The jack end (3.5mm plug?) that goes into the headphone jack of my speakers goes into that tiny hole kind of hard I think. It seems that I have to give it a pretty good push to get it to go in all of the way. And it's not a smooth push either!
There is nothing on the jack end of the headphones nor is there anything in the hole of my Logitech speakers that the headphones plug into.
I get the same results when I plug the headphones into my police scanner's headphone jack-it goes in kind of hard.

So.......I was wondering if there was something I could apply to the 3.5mm plug on my headphones that would "lube up" that plug and make it go into those holes easier?

Does anyone have a suggestion that would work but not cause the 3.5mm plug to get "gunked up" after awhile or gunk up the headphone jack hole in my speakers or police scanner?

The only thing I have here that I use to lube up o-rings is clear silicone grease but I'm not sure if that would work or not.

Thanks,

Some are designed that way to keep dust out.

Hi Steve. I’ll bet a very light touch of the silicone lube would help. Maybe just a tiny tooth pick dab on the end of your finger and then lightly transferred to the plug might just do it. Less is more. You can always take it off with lighter fluid if need be.

Are you talking about the clear silicone grease that I have here or are you suggesting something different when you say silicon lube?
Sorry if I seem confused but I don't want to use the wrong stuff!
