It arrived in great condition, and when I connected it to the iPhone 14 Pro, it was detected immediately; I didn't have to go through any process. They are simple, but you can definitely hear a difference between using it and just recording directly with the phone.

For the price, I believe there could be a percentage charge indication since cheaper devices have this feature.
But this brand has better audio capture.
Important: I have 2 phones from different brands and native OTG, but it didn't work.
To make it work, I entered the developer options, activated USB for data transfer (by default it only charges the phone), and it only works with the Open Camera app or another app (to configure audio with an external microphone) because the native app does not recognize the microphone.

Arrived very fast. From first use it seems very nicely built and very good recording quality. Very nice vfm.

Excellent product, very good quality, an excellent option in its price range.
Charging case helps a lot, good quality in audio recording.
I recommend Ulanzi products; they are worth it.

Very good for the price. The audio quality is decent. I plan to use them to quickly record content with my phone.
