Deuce7Offya and for the mute button add on comes around $12 after shipping may vary per person. Honestly they got me, $12 for just a button is a little ridiculous...but what can you do.
7riFluxI was about to buy this until I realized the modmic 5 was on sale for $60 today. It comes with the mute built-in, modular cables, both omni/unidirectional modes. I can see how that wouldn't be worth $25 for a lot of people, but if you include the mute, the difference is really $60-47=$13 for modular cables and having more than one mode. I was hoping the modmic that would appear on Massdrop would be the v5.
