Hi kazuviking
Have you seen Alexcp's protection circuit?

This is a Power-on delay and DC detection circuit using comparator LM339.

Have a look at the AMB Epsilon 12: https://www.amb.org/audio/epsilon12/
Be aware that it does not work with single-supply amplifiers.

Nah, in 43 years since I purchased my first headphones, a Koss Pro4AA, I've never had some issue to worry about.@wiseoldtech Better safe than sorry.
Why would anyone need to worry? - damage from overload?
Damage due to the cheap chinese quality?
What?
Ya turn the music down and enjoy the ride.
@wiseoldtech I don't trust any piece of electronic equipment even it its 99% safe. For me a protection circuit is mandatory even in low power devices. If something happens i wanna keep my iem's and cans safe from any type of damage.
@DontHertzMe Thanks.
@DontHertzMe Thanks.
I agree. My headphones are worth a lot more than the amplifiers that drive them. An event that puts DC or a very high level AC signal on the output of the amp will destroy them.I don't trust any piece of electronic equipment even it its 99% safe.

diyaudio store has a speaker dc protection board
Seems like it should work for headphones, I think you can tweak the dc voltage trigger point if you want to.
xrkaudio sells an already assembled speaker protection board, I'm using it in a project I'm building.
