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 Punk Espinoza

I bought this instead of a branded unit to try to save money and ended up wasting my money because I couldn't even return it (other reasons for UPS ignore my pickup). There was no sound in one of the ears. I changed the key and the other had the same problems. I used the headphones in another device and used different headphones with the device and the problem was not with the headphones or the device. I bought a proprietary key which unfortunately is twice the price and doesn't allow you to charge the device at the same time, but since then the proprietary key has been working fine. Don't waste your time with this product if you don't have free time and you are sure you can reach the post office/UPS warehouse when it is out of order.
