Dual headphone adapter
A dual headphone adapter, also known as a "headphone splitter" or "audio jack splitter", is a device that allows two headphones to be connected through to one audio jack. They can be used to listen to audio through multiple audio input devices, such as headphones on devices such as an MP3 player, CD player, modern Computer with audio-out compatibility or boombox. Although earbuds, a type of headphone design, can be shared with a bud, a dual headphone adapter can be more practical. Dual headphone adapters can be purchased at various audio and electronic stores. Headphone adapters can be used by inserting a 3.5mm Audio jack plug into the headphone jack.
