They don't support the mic over wired connection which is unfortunate, as even apple products are limited to pretty bad mic audio quality over bluetooth.

I realized this issue when I replaced a set of wire/bluetooth headphones with a new pair, and noticed the mic quality was way worse, even when wired. It turns out my old ones had a wired connection for the mic, and my new ones always use bluetooth for the mic.

After googling a bit, I found there's still no high quality microphone audio profile inside bluetooth, even after all these years.
