i have problem with micro Razer Blackshark V2 X

Hello, I have two pairs of identical headphones (Razer Blackshark V2 X), one bought 3 years ago, and the other I bought yesterday exactly the same, and the problem is that the new headphones have a bad sound from the microphone in my first sound clear and loud, in the newer ones the sound is as if I am standing a kilometer away and talking, maybe this is due to the revision of this model (like the microphone has been changed over these three years), or I forgot about some settings
