The Edutige ETG-003 3-pole to 4-pole microphone adapter lets your 3-pole EDUTIGE ETM series microphones work with 4-pole devices that have a 4-pole audio/mic jack. That means your ETM series microphone can now work with a bunch of new devices.
The ETM series microphones are 3-pole (trs) microphones that will not directly work with 4-pole (trrs) devices. Thanks to the ETG-003, you can now connect an ETM series microphone to your iPhone, or any other iOS device, or other popular smartphones and tablets.
Microphones: 3.5mm 3-pole microphones like the EDUTIGE ETM-001/ 003/ 006/ 008
Recording devices: devices with a 3.5mm 4-pole audio/mic jack such as iPhones, iPads, Samsung Galaxy phones, and tablets.
*For iPhones 7 or later, you will also need an Apple lightning to 3.5mm adapter.
