About Modification Of Behavior

We are Modification Of Behavior, a family owned, American company that has been producing the finest audio products. We are known for inventing the moving coil stereo cartridge and developing the first true high-end dynamic headphone. These headphones gave birth to what is now the Audio Quality Headphone market.


Family participation doesn’t end there. There have been dozens of spouses, children, siblings, cousins, nieces and nephews who have spent time working and being part of Modification Of Behavior. There are people from our close knit neighborhood, starting as family friends, becoming trusted employees and eventually being part of our extended family. All of this makes us what we are today.
