Someone explain to me how DQ6 has any right to sound as good as it does for $20. Kinda feel like an idiot tbh for having spent so much on other IEMs...
I will invert your question in my attempt to answer it. Should the question be: how do we have the right (or rather opportunity) to buy the DQ6 at $20?
In my view it is pure fluke, quite apart from others' point of view that KZ has the principle that, "if you throw enough mud at the wall some of it will stick", or similar analogy, which others have used. The question here is who are their products aimed at? I firmly believe their products are primarily aimed at the Chinese Market. In the commercial sense we (outside China) probably represent a small percentage of the business KZ does. When you have a potential audience of 1.4 Billion in your local market, you do not need to aim elsewhere first, in my view, we are firmly secondary.
I believe, the multiple KZ and CCA BA sets were aimed at the Chinese market and in many instances the tuning reflects that, but also the prices reflect the target market.
Moving on to the materials, I believe that the least costly materials for earphones are the BA and Dynamic Drivers. Having used multiple BAs, there is no harm in using multiple Dynamic drivers as the unit cost can be maintained.
Which brings us to the KZ DQ6 specifically, I believe the mid-bass would have been harder hitting if the primary aim was to market the DQ6 to those of us outside China, do not get me wrong, I like the bass balance in favour of sub-bass, that is my preference. In my view, the tuning was not aimed at those of us outside China, but more importantly, the prices were not either.
I do not believe that had KZ envisaged the DQ6 would be anywhere as close to the 3DT in sound quality, we would be paying the prices we are paying for the DQ6. Yes, the principle of, "pile 'em high, sell 'em cheap" would still apply, but at $35 to $50 not $20.
That, in my view, is why we have the opportunity to buy the DQ6 at $20....pure fluke that we like the tuning, which was not originally intended for those of us who are not KZ's main target audience.
These being my first KZ earphones, please do not misunderstand me, I am sure KZ has produced some good and even exceptional offerings, all I am saying is that KZ is a commercial entity, it would have asked for more money, if they thought, at the outset, that they could get a higher price for the sound quality of their product, the DQ6.
