Scosche CAAP StrikeLine USB Type-C Headphone Adapter with Female 3.5mm Aux Input and USB-C Charging Port for Mobile and Music Devices, Black

Just what I needed for my headsets when phone is on charge.

The adapter worked great for about 3 weeks. After 3 weeks I began hearing a little bit of static, only when the power was plugged in. After another 2-3 weeks, I began hearing a very loud blast of static sound. I would have to disconnect the cables and wait a few seconds, then reconnect. The sound would go away for a few hours then come back. I still use the device and it still works well. The blast of static is a bit of a pain though.

I got the USB-C version for my s20 so I could charge while I listen to music. It emits a high pitched ringing sound whenever it's plugged in, even when no phone is connected. The volume level is extremely low and the sound quality isn't very good. My single function adapter is way better, and even bluetooth sounded better than this. I'm returning it and will continue looking.Also notable that the plug on this is kind of large and doesn't fit without stretching my phone case.

That it stopped working in less than 2 months
