I have heard that the eyeglasses type (or the cigar-butt sized over-the-ear type) are poor quality. Perhaps good for landscape shots, but .... aren't going to get crisp closeup shots, for like showing a coin, or your screen readout on a signal, etc...
And yes: In years past, the go-pro type devoted video cams were about the best you could get. HOWEVER :
Yes, the smart phones of the last couple of years has advanced SO much, that their video quality is akin to the go-pro's now. And ... sure, you're going to look mighty goofy with a cell-phone somehow attached to you. But , sheesk, SO TOO does the go-pro look might goofy strapped to your head too, eh ?
Here's how I mounted my Samsung Galaxy x7 : I took a base-ball cap with a stiff duckbill portion. Adjusted the bill upwards (like the gangsta fashion). Then I use my beltclip to fashion /mount the camera to the duckbill, so the camera aims downward to my feet. Then secure it with some added shims and duct tape (to keep it from jiggling as I walk). And it works perfect: It aims right down at my hands, machine, feet, and a nice circumference of my swing swath area.
And since the headphones I'm wearing are very close to the camera, it actually picks up the audio WITHOUT having to un-plug the jack. Although ... when I get a good signal I want to hone in on, I take the headphone jack out for fuller/louder audio anyhow. And when You stoop down to dig, the camera stays aimed at the dig area of my hands.
In the old days, there wasn't the video time/length allowed on cell phones. And/or it ate up batteries quickly. But today's cell phones can shoot continuous video for seemingly over an hour . Without running out of space or batteries. And even if you do run the risk of faster battery usage, you can solve that by getting one of those external battery pods. And running a chord from from pocket , under your shirt, up to the cell-phone.
