Honestly, go all in.<p>Find a good website name. Make business social media accounts. Do product reviews on your blog with an actual human being reviewing them and some decent footage.<p>Maybe get an audio capture card rig of decent quality, like a focusrite scarlett and a behringer DI box with RCA ins so you can record the outputs of the different devices and analyze their audio bandwidth output, noise floor, any "character" or "coloring" that the device adds to the output (which are entirely personal in nature and unquestionable)<p>Do some screen recording using OBS with the results, nice voice over, post to youtube, write the blog, and fill the space with your personal human recommendations and dropshipping links to the shopping page of your website and if the wave hits you'll already be on your board ready to go.<p>Sounds like a lot of work but if you take it on as a passion project absolute worst case you're out $1,000 and 6 months of your free time as you learn the ins and outs of running a business and trying to make something happen.
