I own the XLR version and while its a very good mic, there is 2 issues i have with it.
For one, the microphone is a condenser microphone.
This type of microphone is perfect if you have more than one person talking as audio can be picked up around the mic.
However for me i find that jarring.
Im the only one that ever speaks into the mic, but lets say my family members are generating noise outside my door, sometimes outside my window or walk in to say something, it is all picked up.
It's basically a very sensitive mic but It's mainly the environment you use it in thats the issue.
Im obviously recording in my bedroom and not in a studio.
Alternatively, if this is the case for you, I would recommend looking into a dynamic mic.
A Dynamic mic only pics up from the top of the mic (Where you'll be directing your voice) and drops off at the sides.
However, you will only have the option of it being an xlr and will have to invest into a mixer that supports a usb connection or a usb audio interface to connect it to your pc.
The mic will also have to be close to you when you speak.
Secondly, the mic is quite big (This also apply's to the dynamic mic as well).
I have it on scissor arm and it either covers my monitor or hides the keyboard.
You will face this issue with any standalone mics.
Im personally going to sell my at2020 soon for the reasons i stated above and invest into a broadcast headset with a dynamic microphone (Audio Technica BHPS1, this will also need a interface/mixer).
Im kind of tired of hunching forward to use the mic and look over it to see my peripherals.
The at2020 mic is a very good mic tho.
It produces no interference like static or buzzing and provides great audio recordings.
If you aren't picky like me, stick with it
My gripes mainly are it's too sensitive and that its in the way.
