Audio quality over headphone jack

[tobimarktobimar]

Hello,

This problem seems not appearing in the forum at all so i posted this new thread.
Does anyone have any issues with the audio quality with headphones over 3,5 mm headphone jack?
Any headphone i checked (Beyerdynamics Custom One Pro, DT 770 Pro, included Asus Earbuds, In-Ear Phones by LG) - the audio quality is terrible. Let me try to explain what i hear:
Every time in the music song loud parts appear the phone regulate the overall loudness down and when a quiet part comes the phone correct it somehow up... Which sounds very Weird cause there is a delay in this... So the song sounds like crap.
I tried to get used to it but no. Every time for e.g. the Refrain stops and a verse comes, the music volume drops and rises weird...

Open audio wizard and click the small headphone icon on top right. Click headphone effects to on and headphone profiles> overhead headphones to general

This makes things worse. I tried it and it sounds muffled on all my tested headphones. I tried all 'effects'. But it's just an software overlay. Nothing that really brings the raw music into the headphones.

Anybody a solution yet or the same problem?

I have Bowers & Wilkins P5 wired. I have put the output to "traditional" and selected the model from the list and also adjust the listening profile. Than I go to custom profile and play around with the equaliser. I am satisfied with results. My reference in portable players is Pono. This is not Pono level but it sounds much better than any of the 4 Samsungs I have in the house.
