Description
The Formcase audio adapter lets you use your wired headphones on devices with USB-C – and charge the device at the same time through the second USB-C port. Music, podcasts and calls keep going, even during long use. The built-in digital-to-analogue converter (DAC) delivers clear, digital sound; with headsets with a microphone and compatible devices, the microphone works too.
Just plug it in – no drivers, no app. Note: the device must support audio via USB-C; please check before buying.
