Expensive does mean higher quality if you know the right brands to pick*. Case in point, $180 for Sony Link Buds is pretty bad deal! There are much better options at the same price range like Apple Airpods, Samsung's AKG tuned Galaxy Buds or the higher end Sony XM4s or XM5.
Obviously there are many companies that do rely on branding to jack up prices like Beats or Marshal. But there are also companies that do no to little marketing and instead focus on craftsmanship where the majority of the cost is going into higher quality experience. And in those segments there isn't really some magical way to reduce costs. Akko is getting pretty popular, but their high-end IEMs like the Obsidian are still going to be in the same price-range as Sennheisers or AKG.

You can't base decision on brand, no matter ho much a bunch of screeching morons on the internet tell you you can. You have to also consider how much the company cares about the product line, how core the product line is to the company, where in the lifecycle it is, etc, etc. The brands that people herald as good are very capable of phoning it in or whoring themselves around. Kitchen-aid slaps their name on all sorts of garbage outside the core products they built their name on, to pick one example of the latter. And the brands that people herald as bad are very capable of producing very good stuff when the incentives align.
