The thing is that the best choice of a microphone for recording vocals is individually a very sensitive thing, where it’s often not about finding the microphone that necessarily sound most neutral, but rather sounds natural to your own reference of how your voice sounds to you, in your head. I’m sure most of us think our own voices sound somewhat strange when hearing a recording of them the first time, and that to the point it’s quite embarrassing.
I did go through many microphones before I found the one I could accept in accordance to how I think my voice sounds, or want it to sound. As the main reasons I bought most of my microphones wasn’t for recording vocals, and rather for recording instruments, I could try a few microphones to find the one that works for me.
I don’t find the AT PRO37, the AT4033a, the EV RE20, the Cascade Fat Head II, or the Line Audio OM1 (my microphone for speaker measurements), to suit my voice particularly well, but I really like the Warm Audio WA-47jr. That microphone makes the recordings of my voice come close to how I hear myself, and that makes it way less embarrassing for me to hear as I’m pretty far off from being a singer.
So, ask yourself what purpose finding the most “neutral” sounding microphone has in the application you are going to use it for. Is it really important if someone used to your voice in real life thinks that your recordings sound exactly like that, or if it may be better to just find a microphone that makes the recording of your voice sound closer to how you perceive how it sounds.
