SaramonicSmartRig+ UC Two-Channel Audio Interface for USB Type-C Devices

Very useful product for 2 track audio recording in a USB-C smartphone. I use it with a Huawei P30 Pro, and works perfect. The XLR/TS combo connectors, allow for microphone or instrument level signals, and have a preamp for both. Is not hifi grade, but it's silent enough for basic purposes. Additionally, there are 2 line level in ports (1/8" connectors) in each channel. The incoming level of both, is controlled in the external device (synth, CD or mp3 player, etc). This means that you can record 4 signals, mixed to a 2 track recording: 2 mic or instruments, and at the same time, 2 line devices. The fact that it uses a 9V battery is an advantage. Otherwise, it would drain the cellphone internal battery. Only downside is the construction: plastic on the flimsy side.

Very good product I really like it

Dont even bother with this.

Works perfect for my needs!

Extremely disappointing that Saramonic did not adequately test their firmware for compatibility with popular iPadPro video capture apps that work just fine with other brands of USB-C audio interfaces. Gain knob too sensitive at the low end. No gain control at all over the headphone output, which can make it un-usable. Record mode was not stable, play mode did not work at all.
