Review on Apple MFi Certified 2Pack Lightning to 3.5mm Headphone Adapter: iPhone 2 🎧 in 1 Dongle Charger with AUX Cord Splitter - Compatible with iPhone 12/11/XS/XR/X/8/7 by Marquel Rubio

This might work for you if that is what you need. For me, I wanted to be able to charge the headset and use it to play games. First problem, I couldn't use the microphone. When the in-game microphone is off, the audio from the headset is normal. As soon as I turn on the game mic, the sound comes out of the phone's speaker. After a few days I decided that everything is fine, let's turn off the microphone while charging, and then I found the second problem. I played with the mic off so I could hear the audio from the headset plugged into the charger. For almost 40 minutes the percentage stayed at the same number, neither increasing nor decreasing. This doesn't work for what I need.
