Researching isn't necessarily productive nor does it necessarily confer any real insights. I still am not sure how to research the right Lenovo laptop for me if I were willing to buy one. It's a mess. Same with headphones: in just minutes of research, you're stuck basically reading marketing and reading forum recommendations. Both of which will likely steer many people to Airpods anyways.
You're taking it for granted that you have some specific needs, know how to evaluate the product space for those needs in mere minutes, and are happier with a cheaper product.
Frankly, having owned various bluetooth headphones over the years, what I always love or hate about them isn't something I knew until I owned them. How much I like/hate their button UI, how they fit and stay in my ears, how reliably they pair or handle bad connections, if they can work through my thick kitchen wall so that I can leave my iPhone in the living room, etc. aren't things I can just research ahead of time. Yet they are 99% of what matters to me. Makes sense to me that people just cough up the $160 for the almost unanimously-loved Airpods instead of enduring the trial and error of evaluating buds.
