I'm not quite sure how to word this properly, so please excuse my possible lack of descriptive ability.
I'm looking for some kind of plug to insert into a headphone jack, so when there is no headphone plugged into
a phone or portable headphone amp, no dust or dirt can get into the device.
Does such a thing even exist?
I carry a portable amp in my pockets, and anything from sand, to bits of clothing dust balls are floating in my pockets.
Most of the time there is a headphone plugged into the jack ( getting from place to place ) , but usually once I arrive at my destination, I unplug my headphones from the headphone jack.
At this moment, I would like to know that nothing can enter the headphone jack.
Hope this makes sense, and someone can point me in the right direction.
