Saramonic SR-C2002 3.5mm TRRS Female to Lightning Adapter Cable for Audio to/from iPhone (3")

As long as you have a mixer with a 3.5mm TRRS input/output, then yes. Many newer mixers do, like a mixer that I have from Zoom. If not have a TRRS in/out port on your mixer you will need a proper splitter that splits the audio out from the mixer into the SR-C2003 and the audio out of the SR-C2003 from the phone call. The Azden i-Coustics HX-Mi is perfect for the splitter you will need: https://www.bhphotovideo.com/c/product/1030239-REG/azden_hx_mi_cbl_audio_adapter_with.html

While it has the desired connectivity, the Saramonic SR-C2002 3.5mm TRRS Female to Lightning Adapter Cable for Audio to/from iPhone is not specified for this specific use with the Apple Airpods Max and PC connection, and may or may not work as desired.

No, the Saramonic SR-C2002 3.5mm TRRS Female to Lightning Adapter Cable for Audio to/from iPhone (3") BH #SASRC2002 is not compatible with the Sennheiser MKE 440. You can make it work in stereo by using the Saramonic LC-C35 Locking 3.5mm Connector to Apple-Certified Lightning Output Cable BH #SALCC35 along with the Hosa Technology GMM303 3.5mm Female Stereo Mini to 3.5mm Female Stereo Mini Adapter BH #HOASMFSMF.

No, it does not.\

No. The Saramonic SR-C2002 3.5mm TRRS Female to Lightning Adapter Cable for Audio to/from iPhone is intended for use with a microphone or a mic level signal. The output signal from a mixer is line level which is much louder than mic level, so you will need to use an attenuator or level matching cable between the mixer and Saramonic Lightning adapter in order to pad the line level signal from the mixer and bring it down to mic level if you want to connect it to an iPhone. If your mixer has XLR outputs, you can use a cable like the Sescom Dual Female XLR to 3.5mm TRRS Plug - Line to Mic Level Summing Cable for Mobile Devices - 12" (B&H # SEIPSUMXLR12). If your mixer has RCA outputs, you can use the Sescom Stereo RCA to 3.5mm TRRS Plug Line to Mic Level Summing Cable for Mobile Devices - 12" (B&H # SEIPSUMRCA12). If your mixer has 1/4" output, you can use the Sescom Dual 1/4" Phone Plug to 3.5mm TRRS Plug Line to Microphone Summing Cable - 3' (B&H # SEIPSUMTS3).

It is designed for a better quality TRRS microphone input for a better recording with apps than the Apple adapter which is designed primarily for headphones and using the microphone on calls.

Tried using the cable to connect an external TRRS wired microphone to an iPhone. Never worked properly, too much crackling interference on recordings. Ended up buying a new microphone with direct Lightning connection.
