Review on 💽 Grey USB C to 3.5mm Headphone and Charger Adapter - Xumee 2-in-1 Hi-Res DAC Dongle Cable for Pixel 4 3 XL, Galaxy S21 S20 S20+ Plus Note 20 - Fast Charging and Aux Audio Jack Compatibility by Vivian Eker

Pros: Perfect if you like wired headphones and can't rely on Bluetooth headphones always being on for calls. You can also charge your phone with wired headphones. Cons: This is the only reason I gave it 4 stars. Although you can charge it, fast charging with a fast charger will not work when using this product. I unplugged/plugged it back in to indicate fast charging, but it either switches back to normal charging immediately or takes a few hours to fully charge. It usually sticks to normal charging, but you have to unplug and plug it back in for it to stick. I would still buy it if you need such an adapter. It works flawlessly and once you get to work or whatever it will charge and you can still use the headphone jack as a bluetooth headphone replacement.
