Solved! Why are my headphones sounding distorted?

[Pelps]

Precisely, voices of people sound distorted not beats and it's not the headphone it is the headphone jack because I've tried it on other devices. Lenovo Legion Y740. Any tips? Corsair HS50

Check for a newer BIOS and audio driver for the system. Headphones plugged in directly to the jack without any other adapters?

I've done it several times

Check with another set of headphones and/or speakers and see if those sound the same way. Make sure the audio settings are set to stereo sound without any other sort of adjustments of audio processing.
