No dongle? The whole thing is a giant dongle hanging off your computer. Headphone cables are far more annoying than mouse cables IMO, and they even affect the sound because it's quite audible when they hit or rub on stuff. Plus I find it surprisingly useful to be able to get out of my chair to grab something while still listening and/or talking. I can even go to another room.
It's just the typical wire vs no wire trade-off combined with personal situation/preference. I see your perceived disadvantages and advantages, none of which I have had ever issues with which made me want to fix something in my particular setup, and think: as long as I don't ruin the cable my headphones just work on my external soundcard and with my music player (and with every device which has a 3.5mm jack), and I don't have to charge them. Good enough for me. And this might depend on culture or particular job, but if I'm in a meeting I can just say 'brb gonna grab something' and no-one cares.
edit oops there was already a whole comment thread lower on the page essentially saying the same things, sorry about that
I distinguish between a casual voice chat and an important meeting/presentation, casual I often take on the go and use whatever is the most convenient option (definitely not a proper headset... bone conductors more like it). At an important meeting I usually don't walk to another room.
And if you specifically mean the cheapest possible models, yes wired will have cable noise, but wireless will have horrible connection and battery issues, so let's assume we are talking about a good above-average model and in that case you can expect no cable noise.
I once moved to the couch while wearing wireless headphones and accidentally fell asleep at an important meeting. Thankfully I didn't need to speak anymore (I think). A wire anchoring me to the desk isn't the worst idea...
Sometimes you gotta do boring meetings, and sometimes everyone has to be there.
Most of them could be better, have fewer people, be more focused, etc. -- sure, no doubt. But you can't make every meeting into an action-packed saturday morning cartoon.
Like, these compliance forms ain't gotta fill themselves out, and each team has to be there. These JIRA and code-review meets are gonna be lame, but we gotta do em...
