I recently bought a rode smartlav+ mic to use with my iPhone 15 Plus and a suitable TRRS USB-C adapter (Cubilux Splitter with mic monitor) but nothing I have tried is working for the mic to be picked up by the phone. I am at a total loss as to how to get this mic to work with my phone.

Hey there Moira_25,
Thankyou for sharing your issue in a detailed explanation.
It seems that you are facing some issues with the Microphone not working with your iPhone 15, not to worry this guide below should be able to effectively resolve your issue.
What You Need to Make This Work
For iPhone 15 Plus (USB-C):
Rode sells the Rode SC6-L Mobile Interview Kit for Lightning, but for USB-C you need a USB-C audio interface that supports TRRS input, like:
Generic splitters often fail because the mic bias voltage (plug-in power) isn’t correctly passed to the iPhone.
Correct Wiring / Standards
Apps vs System Mic
Some apps (like Voice Memos or GarageBand) are picky about which input they use. Once the mic is recognized, you may need to select it manually in the app. If it’s not recognized at all, the issue is almost always adapter incompatibility.
Recommended Setup for iPhone 15 Plus
Alternative: iRig Pre 2 or Shure MVi with USB-C cable.
Key Notes
Direct TRRS splitter solutions rarely work with USB-C iPhones; they often need a powered interface.
You can’t just use any TRRS-to-USB-C cable — it has to provide microphone bias voltage and be CTIA-compatible.
Once you have a proper interface, the mic will work immediately with most apps.
Feel free to reply if you need any additional further support with this and I'll be happy to help.
