RealTalk Lightning Cable for Beats Solo 3 and iPhone Xs Max

I have wireless Beats Solo 3 headphones, but they often run out of a charge when I don't have a power outlet to charge them. Is there a real talk lightning cable that I can buy separately, so I can plug my headphones into my phone and still listen to music or talk on the phone while simultaneously charging my headphones? If not, it would be helpful if Apple made one...
