I would say this isn't true for products on the cheaper end. Under 1k you mostly get what you pay for, but what you pay for might be better build, or better style, or better SQ.
That said, 1k+ headphones still have to hold their value and make you feel the money was well-spent. Abyss has evidently achieved that with the build quality and an imperfect yet competent sound.
However I think once you get up to that price you're in delusional territory. The figure is so ridiculous that I can't imagine my inhibitions wouldn't be suppressed just to hit the "buy" button.
This is all speculative of course. I don't own any kilobuck headphones.
It may be true at the very low end that you could expect quality to not be stellar, but I'd like to see evidence that a $1k+ headphone performs that much more than a $200 headphone as a general rule.
We see this in headphone amps and DACs. The component materials are so cheap, and the semiconductors are of a high enough quality that you don't need to pay over the odds and in general, price should really only scale with the number of components. Add in a style/brand tax and that's your asking price.
For headphones, if a particular transducer, as an example, was more costly to manufacture but had better frequency response and lower distortion, that would be a justification for higher price. So would using lighter but more durable materials, better warranty support etc. When it comes to these so called "high-end" products, I'm still not seeing what justifies the price, other than relying on the "price=quality" belief.
Are there any super expensive headphones that are widely considered to be junk?
