I use a Sennheiser GAME ZERO for audio calls on a regular basis, including professionally, because the sound quality is quite good for voice. (I do also use it for gaming, and for music listening.) For audio calls they're not going to see it anyway, and I don't think most of the people I talk to would care if they saw it on a video call; the design doesn't scream “business”, but the red metal tracery is the only flashy thing about it, and that's kinda subtle.

What's more of a problem I might run into soon is that my setup was already out of date for video calls; this seems increasingly like a hard expectation rather than an optional plus; and the pseudo-docking way I use my primary laptop at my desk doesn't currently allow me to orient the builtin camera so that it catches my expression at a reasonable angle while also letting me leave the monitor in front of me. Putting the laptop where my monitor currently is might be workable, but it could also get squint-inducing at that distance… I might have to play around with this.

Nah, thanks, I have to do video calls with customers, they might find the flashing cat ears somewhat strange.

Gaming headsets are actually pretty good for video conferencing. I got a pretty cheap one (£20) from a major UK chain as a test. Has worked wonders, even if ear fit is not perfect (bit heavy compared to what I normally would wear) and sound quality sucks for music. The alternatives would have been £70+ fancy sets, but I wasn't in the mood of experimenting with those kind of ticket prices.

Others at the company have bought similar items over the past couple of weeks too, and they are an increasing presence at conference calls. I wouldn't be surprised if the non-blinkenlight variants were the next item to go on scalpers' hot list.
