@GREQ you were right!!!! It was a short hair touching the driver!!! I had to find it looking very carefully after removing the big pads and taking it away with pliers... Distortion is gone, thank you so much! 😊😊😊

Hello everybody, I posted here some time ago in order to have advices for a planar headphones and in the end I opted for the hifiman he400i 2020 as an entry level. I have been very pleased by the sound since, but lately I noticed a weird issue when listening to some piano recordings: it's like...

Thanks for the super exhaustive reply!! I understand what you're talking about, referring to RAW in photography. It's a constant research, and if the master isn't good enough even the best pair of headphones will not sound well... And I am with you in the battle against useless megapixels :) I...
