The PowerDeWise Professional Grade Lavalier Microphone is compatible with all iPhone models.
The iPhone 5, 5C, 5S, 6, 6Plus, 6S, 6S Plus, and SE models have a 3.5mm headphone jack, so there’s no need to use any adapter with these models.
However, iPhone 7, 7 Plus, 8, 8 Plus, and X require a Lightning to 3.5mm jack adapter because these models don’t have a 3.5mm audio port, so you will need the Lightning to 3.5mm adapter that came with your iPhone (Please check your iPhone Box, should be inside) to connect the microphone to your phone.
Again, you don't need to purchase the adapter separately, it comes with the iPhone 7. Nevertheless, if you can’t find yours anymore, please purchase a new one from Apple.
Here’s what the Lightning to 3.5mm jack adapter look like:
If you can’t find Lightning to 3.5mm jack adapter that came with your iPhone, please we would recommend that you purchase a new one directly from Apple, not another brand.
