I see where you're coming from. I feel it's more like: you've never heard of a product. All of a sudden every YouTuber is shilling raycon earbuds.
Well that's the only place I ever hear of them. They all say they're great! I've never seen them or had anyone else attest to it except ads that all came out of nowhere. Seems like a play to make big moves in the headphone market. They sure did spend a lot on marketing, I hope enough went to design to make em actually good.
Now, I don't own any raycons because as I said seeing this behavior makes me skeptical of the product.
Meanwhile the main headphones I use I've never seen an ad for once. A friend recommend the m50x's when we were djing. I tested em and loved em. After getting them I notice they are basically an industry standard for audio which is my work. I suspect the quality product with savvy ads in appropriate places lead to this situation. No doubt in audio magazines audio technica runs ads.
When every YouTuber has done an incogni, nord, raid shadow legends, or a few others, I have to suspect they spent more on marketing than they did their product which makes me think(and has been shown a few times) that these products kinda suck.
