I tried to record every day things with my action cam and I always feel like a weirdo with a box hanging off, I think these would help me not care about that as much,

Out of curiosity, for what purpose? Do you go back and watch your videos of everyday things? Share them with friends? With photography (and most visual media) the secret seems to be to take many many photos, or draw many many pictures, or shoot tons of video, and then curate and edit meticulously to find just the very best parts. Do you really get much value out of recording lots of day to day video? Is this part of some kind of art project?

At the surface they seem like I’m recording for my parents (we live very far from each other). Deep down I would like to get YouTube income eventually.

Just use your phone or a vid camera normally so that your subjects can understand that you are making a video of them. Sneakiness sucks.

4. On-foot navigation without having to glance down at the phone or watch

5. Being able to converse with friends in loud places (e.g. restaurants have become louder and louder over the years due to bad acoustic design)

My phone and noise cancelling earbuds allow for both of these already. My issue is with an always-on hidden camera and mic — just creepy surveillance junk
