In the end, it plays music much launder than from a standard 3.5mm phone jack and a bit louder than DAC-only solution (because the gain is only 2). The device is capable of driving high impedance (tested with 300 Ohm SennheiserLevel 1. 10-10-2021 11:41 AM. Banhien, You say that "in theory this should work but why you have to use USB-C port when it has 1 prise combinée casque/microphone port.

Usb-C to 3.5mm. I use one and they definitely work, however I think due to how they lock a certain volume attribute in hardware, you can only reach half of the maximum output volume on most android devices. This is a big problem of you're trying to drive high impedance headphones. You can get a USB-C to 3.5 mm Headphone Jack Adapter as a solution. Here are the types of adapters you might need and what they do: Y-adapter (TRS to TRRS) : If you have a double-plug headset but only one 3.5mm port on your PC, the Y-adapter will convert the two plugs into one without losing any functionality. .
