Same here. I want to make a battery powered noise canceling headphone that automatically shuts off if the jack isn't plugged in. Why should a 250 dollar pair of headphones not do this automatically when the battery is required for the experience!?

Because there's a niche market for people like myself that wear noise canceling headphones without music?

Seriously though, if I go in a server room I'm putting noise canceling on. I still need to hear if someone is talking to me, so no music unless I'm doing repetitive work.

Fair enough. I think you are a very small niche though and my proposal would save tens, if not hundreds of thousands of people from wasting expensive batteries. Worth it.

They do do this automatically. You may have been using the wrong type of headphones.
