Question about Onit Digital Audio Adapter USB-C to 3.5 mm AUX

To determine whether the coupling of the "Digital Audio Adapter USB-C to 3.5 mm AUX (Digital -> Analogue)" from Onit is 4-pin, we need to look at the technical specifications of the product. A 4-pin 3.5 mm connector usually supports both audio and microphone functions. Unfortunately, there is no direct indication in the information provided as to whether the adapter is 4-pin.

If the adapter supports both audio output and microphone input, it could be a 4-pin connector. Otherwise it would be a 3-pin plug that only allows audio output. For a definitive answer, it would be advisable to check the product description or the technical details directly with the manufacturer Onit.
