Headphones

Okay so I bought it after reading reviews and responses from people saying that it has good bass and all that and are super great. But the product wasn't as good as everyone had hyped up it as. I'm not saying that it's a bad product but it wasn't up to my taste or expectations. I am used to normal wired headphones and the normal tws oppo enco buds. I like the bass they provide, I'm not into too much or too little, I just liked the perfect amount that I can feel in my ears and doesn't overwhelm the rest of the audio and makes it muffled. The oppo enco are a bit light when it comes to base but not bad, but the lack of bass is clearly visible when listening to phonk and other bass heavy sounds. Now kz zsn pro x have a really flat sound and have a constant hiss that is really annoying, but a lot of reviews mentioned good bass but I don't feel it at medium or low volumes and these kz's get really loud at high volumes so that's a no go for me.

So please tell me what am I doing wrong so I can fix it or simply return them.

Disclaimer: I am not an audiophile and had limited budget so I only bought these and no replacement cables and other possible attachments.
