Any high-end microphone is really. If you want to record your voice for game commentary, podcasts or for any other purpose that requires high-end sound then by all means pick one up. But for VOIP there is little use. My H1 compared to my ZM-MIC1 at the same location picks up way more background noise, but it also delivers a higher quality voice recording.
If you really and truly want the absolute best audio quality when it comes to voice recoding you need the following:
-
A high-end microphone that can record loss-less. My H1 is by all means a budget choice - a really good microphone can cost $400+.
-
A bungee mount that can effectively absorb vibrations.
-
A microphone stand that puts the microphone away from your keyboard, desk, chair (basically any object that you can touch).
I'd also advise to add a pop-filter (not to mention a sound-dampened room; my H1 can pick up the construction workers two blocks away - sounds I can barely hear myself). After this, only one issue remains really; high end audio needs to be processed to really shine through. If you record for podcasts, this can be done easily afterwards. You can edit out noise, reduce jitter, recalibrate and so on. When it comes to VOIP, you cannot.
