Iems and static noise

Hello guys! I have had kz zsn pro, and after I bought ouranos tkzk. My ouranos a year later broke, the left earpeace sound was lower than the right. I took the kz earpeaces, and combined them with the ouranos cable, which actually worked good, until I noticed a static noise sound when I listen music or when I watch videos.

I use it mainly with a Samsung audio jack to usb c.

For example, when I press play on my phone I hear the static noise, if I press pause its not there.

Do you guys think could be the adapter? Or a conflict with the cable?

I know it's a hit or miss with cheap adapters.
