A mini-phone to USB-C adapter is usually a small audio adapter with a USB-C male plug at one end and a 3.5 mm female headphone jack at the other. It lets you connect wired headphones, speakers or a headset with a 3.5 mm plug to a device with a compatible USB-C audio port. In product listings, look for names such as “USB-C to 3.5 mm audio adapter” or “USB-C to 3.5 mm headphone jack adapter.”
What does “mini-phone” mean?
“Mini-phone” is a connector name for the familiar analog audio plug commonly called 3.5 mm or 1/8-inch. It is the plug used by many wired headphones and other portable audio equipment. A mini-phone-to-USB-C adapter translates between that audio connection and a USB-C port; it is not a phone accessory for a particular phone size. Computer Language Company’s definition of mini-phone connector describes the connector terminology.

Which end plugs into the device?
For the usual phone setup, the adapter has a USB-C male plug that goes into the phone, tablet or computer, and a 3.5 mm female socket that accepts the headphone cable’s 3.5 mm male plug. Dell’s Bull Creek adapter listing specifies USB Type-C male and mini-phone stereo audio female connectors, while Apple’s adapter description identifies connecting headphones or speakers with a standard 3.5 mm audio plug to USB-C devices.

Will it carry headphone audio and microphone input?
Not necessarily. A three-conductor 3.5 mm TRS plug carries stereo audio. A four-conductor TRRS plug adds a contact used for a headset microphone. If you need a microphone for calls or recording, check that the adapter explicitly supports headset microphone input and is compatible with the headset wiring. A four-pin socket appears in one active-adapter product data sheet, but that alone does not prove every adapter supports microphone input. DELTACO / Dustin product data sheet

What to check before choosing one
- Connector direction: For connecting wired headphones to a USB-C device, choose USB-C male to 3.5 mm female. Other cable arrangements serve different purposes.
- Audio and microphone support: Match the adapter’s stated functions to your needs. Stereo playback does not by itself establish headset microphone support.
- Device compatibility: USB-C is the connector shape, not a guarantee that a device’s port or a given adapter supports audio output or microphone input. Check both manufacturers’ specifications for your exact device and adapter.
- Implementation: Some adapters include audio-conversion electronics; one cited product is described as active. Do not assume all adapters use the same design or offer the same features.
