The 4-conductor TRRS plug on this cable uses the CTIA standard configuration which puts the microphone signal on the sleeve (versus being on the second ring in the OMTP standard). The CTIA standard has always been used by Apple and HTC while older Samsung Nokia Sony Ericsson and Wiko devices initially used the OMTP standard. However the latest versions use the CTIA standard. This cable is therefore compatible with:
- iPod touch® 3rd Generation and later versions
- iPhone 3GS and later versions
- iPad (all versions including iPad mini)
- Samsung Galaxy S® version 3 and later
- Samsung Galaxy Note® version 2 and later
- Any Android device using the CTIA standard TRRS connector with the microphone on the sleeve as described above
While the TRRS plug is wired to the CTIA standard the TRS headphone jack and TS microphone jack use standard wiring. The microphone input is compatible with microphones equipped with either a TS or TRS connector such as those used on PCs. A combination mic-headphone assembly such as those normally used with smartphones is not a compatible input device.
- Plug the 3.5mm (1/8") TRRS plug into the headphone jack on your compatible smartphone or tablet.
- The smaller of the two 3.5mm (1/8") female jack bodies is the TRS stereo headphone output. Plug your standard earphones or headphones into this jack.
- The larger of the two 3.5mm (1/8") female jack bodies is the TS mono microphone input. Plug your standard PC style microphone into this jack.
- This cable only provides the electrical connections allowing the physical use of the external microphone. To record the signals sent to the device you will need to have a software app such as GarageBand for iOS®.
- If using GarageBand for iOS note that the app generally cancels the monitor output during recording. This can be modified in "Settings" under "Crosstalk Protection". Be sure to minimize the input volume first.
