The latency on bluetooth is killer. I guess most people don't notice, but I notice. There's a irritating delay between every action, and when watching video the sound is noticeably behind.
There is often interference when in frequency-heavy zones. Busy pedestrian intersections, trains, using the microwave.
I switch between devices with regularity. My computer, my phone, my corporate phone. Keeping one set of headphones paired between multiple devices is a nightmare.
I don't like keeping bluetooth on. Why do I need to place yet one more source of power drain on my devices, and why do I need to enable yet another broadcasting signal from them?
Dollar-for-dollar, lower cost wired headphones are higher quality than wireless ones.
I am prone to losing headphones, having them be miniaturized and untethered is not a bonus. Heaven forbid they're not even bound together and are instead individual unconnected earbuds. I can count in the double digits the number of people I've seen before my very eyes lose one half of their earbuds, to say nothing of the number of people I've encountered who are just dealing with losing one of them from some prior event.
Bluetooth headphones are a product with value, but not to me. Not having a headphone jack felt, and continues to feel, like a heavy handed bitch slap straight to my face every single day.
They are $10 each. They can be attached to the end of your headphones and forgotten about.
Even worse: cheap usb c headphones all have shit DACs and will perform worse than cheap 3.5mm headphones.
The audio quality of airpods is still subpar compared to $70 wired headphones.
I listen a lot to classical music and airpods 2 still makes becken (two cymbals smashed together. Don't know the English name) sound like someone throwing a rock into a pool.
I lose several pairs of headphones every year. Headphones being smaller is not a feature for me.
I have one pair of BT headphones. They have about 90ms latency, which is borderline intolerable (but better than every airpod). I use them for podcasts.
I plug my phone into speakers all the time (at work. I am a musician). A 3.5mm jack makes that a non-thinking operation.
