I have one of those adapters. It works fine for listening to audio, but using it for voice is $#@!! I’ve yet to find a good wired headset for USB-C or using the USB-C dongle (on my Samsung) that is good for talking to people. I always get complaints that I sound distant.
This is not a problem specific to Apple. Standard headphone ports have been removed from most phones (Apple and Android). With virtually any modern phone, you must either use Bluetooth wireless headphones or USB-C wired headphones.
Note on : “There will be no new comics next week. Covid. It’s a mild case. Already feeling better, but it has thrown the schedule off. I think the fact that it hit me right after a comic about my experience traveling should not be taken as a coincidence. Sorry for the gap. I’ll be back soon.”
Thank you!
