Sure, unless you want to do something rare and exotic like, say, have a microphone on your headset. Then you get the HFP/HSP profile, which makes two tin cans linked by a string seem high quality by comparison.

But it sure is nice to be able to make phone calls where people don't sound worse than they did with digitally-switched analog landline telephones in 1995. Bluetooth doesn't get there at all.
The losses of Bluetooth even compound generationally: The inescapable tin-can audio of Bluetooth at one end first gets transmogrified by at least one intermediate lossy codec for transmission across/betwixt the network(s), and then gets tin-canned harder when the far end of the connection is also using Bluetooth.
For perspective: 1995's phone calls were ultimately limited by the G.711 codec, which itself dates to 1972. I'm not setting the bar very high here at all.
Of course that sounds like a tin can either way, it's coming in encoded with the quality of a tin can! People here are talking about modern VoIP calls (Teams/Slack/Discord/Zoom/etc) which have a snowball's chance in hell of sounding decent in the first place. HSP/HFP will often crank that right back down to traditional phone network quality again. You also lose stereo, which isn't so bad if the only thing you're doing is having a 1:1 call but kind of sucks for a background group call.
But now that you mention it: Yeah, the state of common VoIP (Teams/Slack/Zoom/whatever) is also usually not very good. It's like there's some huge bandwidth crunch here in 2026 that is driven by the strenuous demands of VoIP, except: There isn't.
When I was doing some live streaming with others in a studio a couple of years ago, we worked with some of that. It never sounded very good. (It doesn't sound very good when the big-time acts at CBS or NPR or Fox News do it, either.)
But! When we occasionally had remote co-hosts who had enough technical competence to make it work properly on their end, we were able to use SonoBus[1]. That audio was positively pristine, like they were sitting unseen in the same room as everyone else.
It's an inscrutable mess.
Wires don't have these problems. Plug them in. Use them. Clean the contacts every now and then if/when they get crudded up.
That only works with A2DP one-way audio. The two-way HFP mode still uses the horrible classic BT compression unless the new BLE-based LE Audio is used(but IIUC Apple still don't support it). Besides there are still many devices that only supports BT's own 2000s-optimal SBC codec.
All that to say.. what's best, cheap, no wires, no headaches and happy or expensive, wires, having to download music and make a library etc and always looking for the next high, the next minor improvement?
One of the happiest days of my life was when I listened to my music on a 10$ mp3 player with 2$ earphones after 3 months of not listening to it.
So yeah, you may be right, even though I've tried 3000$ open-ear audiophile headphones, with an amazing amplifier, listening on tidal and it didn't blow me away but even if it did, I'd be stupid to even try, then I'd know what I'm missing and craving a 5000$ setup when I'm already happy with the 1 inch box I can easily carry wherever I go.
