We were setting up for a concert one time and I was helping the FOH engineer (sound guy) check all the instrument/mic lines. One of the instruments was a Moog synth. I started randomly playing it (I do not play piano or synth) so he could check it. After a couple of seconds he said something about me playing a song and I told him I had never heard of it. Apparently I had accidentally played the opening of a song he really liked.

My wife’s family drives like this, not just with the pedals but with the wheel too. Instead of turning it to where it needs to be and holding it they turn it to far then over correct back twords center then back to the first spot they turned it to, then overcorrect, and repeat the entire turn. Thankfully I was able to get my wife to stop driving this way when we started dating and now she hates riding with any of her family driving as much as I do.

For the use case scenario OP described I definitely agree that musicians plugs are the way to go. These Etymotics are what I use as my backups if I don’t have my custom molds with me.

I got my custom molds for concerts from an audiologist, all in they were $150 and well worth every penny. Also, because they are for work, they got written off on my taxes.
