Dual Input Lightning Adapter For iPhone XR

All iPhones starting with 7 to X are using lightning connector for headphones instead of the 3.5mm jack. At night, I want to charge and listen to music before I go to sleep, I got this dual lightning adapter hutou which accept 2 lightning inputs and 1 output to the XR ($7.99), the ports are marked and we have to plug in the source accordingly for it to work. It does work very well for a little price. It does charge with the right USB ports on Laptops.
