I have too many pairs of headphones and have been buying more wired ones rather than Bluetooth as they just don’t last as long (they are convenient, I’ll admit).
The 3.5mm Jack is just so handy to have ratger than a dongle (SD card for storing all the music helps too).
Fair point, I also make a point of only buying ones that have a removable cable for that reason.
I did also recently, as a geeky project, get some Mackie mc-100 headphones and mod them to take a removable 3.5mm cable.
