For many cameras today, the mic-in jack is located on the side of the camera body and your microphone will be pointed to the side when plugged in directly.
The Edutige ETG-002 3-pole to 3-pole microphone adapter lets your 3-pole microphones rotated 360 degrees to the direction you like, forward, backward, upward and downward. It adds flexibility and precision to capturing your sounds.
Microphones: 3.5mm 3-pole microphones like the EDUTIGE ETM-001/ 003/ 006/ 008
Recording devices: devices with a 3.5mm 3-pole mic jack such as DSLRs, mirrorless cameras, Actioncams, and voice recorders.
*For GoPro Hero 3 or later versions, you will also need a proper GoPro 3.5mm mic adapter.
