I’ve got the Bose QC 45 headphones which can do both Bluetooth and 3.5 mm. The audio quality is the same between the two delivery methods. The only difference I’ve noticed is an occasional video/audio synching issue with Bluetooth which quickly corrects itself and is usually only an issue with older devices. It’s my understanding that this and the audio lag issue have been solved recently in newer devices.

I personally think Bluetooth is a shit standard that has slowly been fixed over the years, but it’s pretty much 100% there at this point

The real question I have is: is a decent DAC that hard to find? I bought a shit one because it’s only a back-up option for me, but I can’t imagine the good ones are scarce.
