The format may be relevant, but I think it's mostly just the recording setup. like binaural recording.

 

spotify: ogg(vorbis) AAC
 

youtube: opus m4a(AAC)

 

https://en.wikipedia.org/wiki/Opus_(audio_format)
Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC.

You can start by asking your local audio store or electronic repair workshop.
It's not a difficult job really.
Unless it's a tiny IEM or has a very difficult design to repair.

IEM is very sensitive so it is easy to detect any noise.
Changing cases won't help because that's not where it's coming from.
Some expensive DAC has it too, but it's only noticeable on some sensitive headphones.
A quicker option is a impedance plug/adapter.
About 30 ohms or so is enough. It basically makes your headphones less sensitive.
