I have Focusrite Solo [1] audio interface - I got it for guitar capture initially - then I plugged in my headphones in it and the DAC/AMP in it is amazing - this motivated me to go for studio headphones (beyerdynamic dt 990 pro) and now because of this crisis I went for AT 2020 condenser mic
This setup costs ~400$ so if you are just in to calls I'm not sure if it's worth it - but for me it was just getting a mic and now I sound like a radio host on calls :D
I don't own a GoPro so if there is a clone that has this functionality out-of-the-box it would be ideal.
Problem is the camera has to be sitting in the middle of your screen or it will be looking like you are looking away. Even the built in camera on the bottom left of my dell xps looks stupid. And then video conferencing tools compress the video to shit anyway. Also most of us don't have fancy looking home offices. I'm currently working from a desk in my bedroom so a video call would have my bed and an unpainted drywall covered in plaster lines/patches.
The scarlet focusrites entry level are pretty cheap you can get the solo for £100 less than a nice mechanical keyboard and a decent mouse.
I went for the next level up the Clarret 2pre but I do use that for my dnd streams and want to process my voice and to mix in audio.
Main problem with entry level class compliant usb is your at the mercy of Apple and Microsoft making your interface obsolete and you cant change your microphone to suit.
It is not just the soundcard; but the entire solution.
When I looked it, it was for the microphone (400 EUR) + focusrite 2i2 (150, yeah, I looked at dual) + cloudlifter (150) + boom arm (75) + cables (let's say 25) => 800 EUR. I tried not to think about GoXLR...
Compared to that, NT-USB + boom arm (PSA1) was only 200. Plus the space saved on the desk.
I don't really understand, what you mean with being at mercy of Apple and Microsoft. The only problem with USB mics that I'm aware of might be timing/lag, if you need it to be precise. That could be problem for singers singing to instruments, but not for spoken word.
MS depreciated something in a fall update that stopped my £50 alesis core 1 working and both apple and mac no longer support my TASCAM which is why I needed a new sound card
If your in the uk the SZ-MB1 was only 17.99 compared to 150 for a cloud lifter and for mics I use some 10 year old entry level sure dynamics which where £25.
How are you using the xlr mic? I have one but am using the USB output because I don't have a xlr port on my laptop.
