What source are you using for the setup?

RME ADI-2 DAC FS with a 3.5 -> 4.4 adapter (for every of my IEM's that have a 4.4mm connection). That thing is probably objectively the best thing that exists for IEM's as a desktop unit, it has a 0Ω output that is specifically designed for IEM's. It is super clean and doesn't colour the presentation in any way, while it does not sound sharp or cheap.

hello what brand are the tips supplied with the campur? Thank you

No idea, i switched to Sedna Crystals, those are my favourite tips (alongside Spring Tips). I made a Screenshot of the tips amd added it to the review
