Can an electric drum kit sound without headphones?

Yes, an electric drum kit can produce sound without headphones. Electric drum kits typically consist of electronic drum pads, a control module, and an amplifier. The drum pads are connected to the control module, which processes the signals from the pads and sends them to the amplifier. The amplifier then amplifies the signals and sends them to the speakers, which produce the sound.

Therefore, as long as the electric drum kit is connected to an amplifier and speakers, it can produce sound without headphones.
