@Polychrome TBF you're "supposed" to just support #Bluetooth. You can also theoretically charge a device wirelessly through #Qi and use an adapter to connect to wired headphones or earbuds.
I always find it funny though that nobody points out that #Apple got rid of the headphone jack on the #iPhone because they wanted to make their phones thinner and thinner and the headphone jack was getting in the way of that lol
