Hifiman re400 from Joybuy arrived (costed 25$). I have to say that these have a very beautiful sound, they outclass everything in the budget segment very easily.
I absolutely agree with people saying that these are slightly bass light compared to something really neutral, but I quickly adjusted and it doesn't sound wrong because the bass is there and there is enough of texture. It definitely doesn't sound like it's lacking bass, it sounds like it's purposefully like this. The amount of details that these provide is astounding. I disagree when it comes to sound presentation, these don't make you feel trapped with the music like many reviews make you think and I've already noticed that many instruments have a realistic timbre and echoing in the distance, but they don't sound as far away as they should ideally.
Cables are the worst that I've seen above Y split, thin, rubbery, flimsy, can't get straight, microphonic. Isolation is quite a bit above average but there is no driver flex.
People really like KZ ZS5/6 series and present them as budget kings, but there is no comparison to be honest, they feel classes below compared to re400. I even found re400 to sound more exciting than ZS5 which is a miracle given the difference in tonality.
