This is the latest Firmware to date:
Might well be that a much more expensive microphone from a company like Sennheiser or AKG can do better.
In my daily job as professional audio engineer we are working with microphones costing more than 10 times of what the whole Mobius costs, and certainly there is a difference.
But I've even had headmount microphones (without headphones) costing about what whole Mobius does, which do sound worse.
Anyway - it's a big difference if you have a Directional Mic that suppresses ambient noise like the Mobius's Mic, compared to an Omni which is picking up sound from all around you.
These two types behave completely different when it comes to handle proximity.
The Directional type does react much more extreme when you go closer.
According to my tests you get the best result at a distance of 1.5", tip 3/4" sideways inward from your labial angle.
If you need more level place the mic slightly below your lower lip, pop filter almost touching, pointing 45° upward (turn around the lenght axis).
Don't forget, the "hot" side is where the little microphone symbol is located. There is a tiny bump that can be felt for tactical control.
A foam windscreen / pop filter is an absolute must.
Windows mic level control should be at 100%.
The resulting level (Mobius mic control at max.) with normal spoken voice leaves a headroom of about 6dB below full scale (no headroom with placement #2), just enough reserve for some louder shouts.
If you go closer, dynamics become uncontrolled and sound becomes muffled, so
"eating the microphone" is not suggested.
If the level at none of the proposed positions is sufficient I would not fault Mobius microphone.
If the above doesn't help you're either using a calm voice, or the software you use does not handle microphones the best possible way.
I have to remark that I had suggested
@KMann that AUDEZE extend the mic volume control range by an additional digital gain of 10dB.
This would solve some problems with too low mic level, but would also offer the customer an option to missadjust the level too high and get a distorted signal.
On the other hand it would offer the option to use the microphone more distant.
