Having the option for both is the best alternative.
I have a dedicated DAP that also has Bluetooth- I use a pair of wireless headphones when exercising or doing stuff around the house, a pair of wired cans when I want to kick back and enjoy my lovely collection of lossless music, and a pair of IEM when dealing with commuting - not the best audio, but still good enough to ignore the entire subway and it also means I don't deal with interference!
Losing the ability to choose, or willingly locking yourself to a single alternative is just stupid. Sometimes I'm using my IEM and want to listen to something in my phone - videos, YouTube, stuff send through WhatsApp - and having the alternative to do it wired is nice! If I'm using my wireless headphones, it's also nice. But the best part is that I choose, not a company.
