No correlation between headphone frequency response and retail price
"Log sine sweeps rather than linear sine sweeps were employed to allow verification that non-linear distortion components were virtually absent."And with that, this study is bullshit.Human beings don't listen to linear sine sweeps. We listen to music. Recorded music has 8+ octaves of frequency range (the bottom octave plus a little extra is almost always rolled off in real-world recordings, to ease stress on downstream components that can't reproduce such low frequencies anyway), and 20-50db of useable dynamic range.Sine wave measurements of audio gear ignore impulse response, intermodulation distortion, phase shift, and a host of other real-world physical device responses to real-world musical signals. Scientific, reductionist thinking is inadequate to get an accurate picture of the factors that matter to human listeners.Frequency response and total harmonic distortion aren't measured in these cases because they're useful or relevant. They're measured because they're easy to measure. It's like looking in the wrong place, because the light is better there. And the results? It's like measuring a car's performance by how well it can drive in a straight line at 60mph. Acceleration, braking, and turning are too hard to measure, so we ignore them...I'm a musician and record producer. I've engineered and produced numerous albums, and rely on multiple different types of headphones for different purposes. The article's claim that one headphone can be easily morphed into another through mere equalization is, frankly, bullshit. The two headphones I rely on the most (Beyerdynamic DT880 and AKG K240) sound wildly different. Neither is "accurate". Neither are the Tannoy System 12 DMT midfield studio monitors I use for mixing, or the stock Subaru car speakers I use for reference to check the mixes from the Tannoys.Audio reproduction is incredibly complex and difficult stuff. Trying to isolate one factor and saying "That explains everything!" is bad thinking.
