Can you use normal headphones with an electric drum kit?

Yes, you can use normal headphones with an electronic drum kit. All you have to do is locate the headphone output on the electronic drum module, also known as the brain and plug in the headphones. Typically, the headphone out is on the front of the drum module. I had a Yamaha DTX set and it did require a 1/4 inch headphone adapter. It's great listening to yourself play while not disturbing others around you with loud kick drums and snare beats.
