Sorry, you want to sell me a $75 dollar disposable mic with a button? When i could do the same with a phone or a watch that i already own? Just like the humane ai pin, there is no need to create a brand new hardware device to do something an app won't do. And justifying it saying "we're introducing a whole new piece of hardware to save you from the pain of clicking one extra button" isn't going to fly.
There are certainly situations where finding my phone -> selecting the right app -> and clicking record is too much friction. My ADHD brain would totally get value from this.
