As a consumer in this niche market, I have my own criticisms about the industry and though it might not be in line with popular or mainstream perceptions, but I see this becoming a trend parallel to the mobile devices industry where the consumer has a short product memory.
And currently if you are looking at the headphone market, from 2009 onwards every other manufacturer is releasing a new flagship in every couple of years, this also goes for the IEM and DAP market, where "THE ULTIMATE" digital audio player is released in every 6 months by South Asian Manufacturers at ridiculous prices with the premise that it is a "LUXURY" product, but it is clearly not, as it is poorly made, sound mundane at best and can't even do what an average smartphone does and few even have problems with oxidation, despite being worth more than 5 times a iPhone 6S.
There are some benefits out of this hyper hyped market though, as a few manufacturers and DIY'ers do seem to come out with good stuff once in a while, but it is always a rare find and for me it takes time for gear to grow on you as you get more and more aware of the product from a holistic perspective , which is why I also don't trust these early reviews before the actual product launch.
