It seems like a pretty simple solution to me, make bluetooth headphones that also have an analog jack on them. It may not work for earbuds, but I gotta say my favorite feature of my Bose QC35's is if my device doesn't support bluetooth I can always use the cable to plug it in. It works when the battery dies too. Granted the jack on the headphones themselves is 2.5mm so you need a 2.5mm to 3.5mm cable which makes it a little annoying. Headphone manufacturers should stick to using either 2.5mm or 3.5mm jacks on their headphones. Give the option of bluetooth or no bluetooth. Then separately manufacture wires that have DACs in them. It increases compatibility, potentially increases profits by double dipping, and makes "repairs" simple.
