Not at all, I'm not saying you can't hear the difference between a cheap and expensive set of headphones on Polyphia songs, but the difference will be less noticable than on some other songs because of how it's mixed. Polyphia produces more for cheap Bluetooth speakers than hifi setups.

I feel that if you want to test a set of headphones or speakers properly, you shouldn't test them with something that's made to sound good on anything. Find something recorded with high quality gear and mixed with minimal processing and the differences will be much clearer. Bad gear will sound worse, but great gear will sound amazing.

That's the point of hifi, right? Produce sound as transparently as possible, so that each tiny little detail will sound like it's coming from the room, then trust the musicians and mastering engineers to do the rest

Polyphia will sound good on anything really, their style of music/production fits even cheap gear very well. Anything with decent bass response and stereo sound. Not really the best benchmark imo

If you want to give your headphones/speakers a run for their money, try one of these vids

While My Guitar Gently Weeps, Chapman Stick Wide complex stereo image, deep bass, and a very punchy dynamic midrange

A Flock Of Seagulls - I Ran (So Far Away) Lots of synth SFX, massive sound stage in the intro

Maria Mena - I Was Made For Loving You Great quality recording with very little processing, gradually adds instruments

B.B. King - 3 O'Clock Blues No comment, just listen to it. Pure blues

Igorr & Ruby My Dear - Biquette What it'd sound like if Polyphia found and consumed 7 types of drugs at once

Polyphia tried to destroy the metal, BUT THEY FAILED, as they were smite to the ground.

No, drones are just government birds dressed up as drones
