Apple has changed the connector from Lightning to USB-C on most iPads, and at some point will be changing at least some iPhones to USB-C. To support this migration, we are building USB-C equipped versions of all of our hardware products, and also offering conversions to USB-C from Lightning for existing products.

In addition to our Lightning iTestMic2, we are also offering a factory-built iTestMic2 with a USB-C cable. This model will work perfectly with all existing Apple USB-C products, and as far as we can tell with any future Apple USB-C equipped device.

When you plug iTestMic2 / USB-C into a Apple USB-C device, you will see the familiar “Accessory Found” message, the calibration will be transferred automatically to the Apple device, and the multi-range feature will be enabled. Also, the 3.5mm audio output jack will function as intended.

Device Charging

The only feature of iTestMic2 that that will not work is device charging, due to USB-C power delivery accessory issues. If you require device charging for long-term use cases, you can use any typical USB-C hub that provides USB-C charging. The iTestMic2 / USB-C will work fine through the hub.

For example, the Anker Series 3 PowerExpand 7+ works fine, most likely similar devices will also work. There is one trick, you have to use it with USB C charger that supports 15V, rather than the simple 5V chargers. These are typically called “fast chargers” and would be rated at 35 Watts.

Using the USB-C iTestMic2 with Lightning Devices

If you have a mix of Lightning and USB-C Apple devices, you can use iTestMic2 / USB-C with both. For the USB-C devices, just plug it in directly. For the Lightning devices, the Apple USB-C Camera Connection Kit adapter allows direct use, and some of these adapters also provide charging. Since the Apple CCK has a USB A input, use the included USB-C to USB-A adapter that is included with the iTestMic2 USB-C.

Using the iTestMic2 / USB-C with Mac and Other Systems

iTestMic2 / USB-C works with Macs, and with AudioTools on Macs equipped with an M1 or M2 chip, although only the low range is available, and the calibration must be entered manually. The same is true for other platforms, including Android and Windows devices.

Converting an Existing Lightning-Equipped iTestMic2

It’s not possible to use a Lightning connector iTestMic2 (or actually any Apple MFi Lightning accessory, other than a charger) with a USB-C Apple product, even with a physical converter. The reason is that Apple chose not to include Lightning MFi Accessory protocol support in the USB-C device operating system. However, we can change out the cable and firmware of a Lightning iTestMic2 with a USB-C cable, and the iTestMic2 will then work perfectly with the USB-C devices, although without the charging feature.
