Pros turning volume off?

I see pros just go into settings and turn their volume to 0 after they die sometimes. In ranked/streaming would be one thing but even in pro games you see it sometimes.

Anyone know why? Seems like it would only be a hinderance if you wanna help your team after you die in comms

to comm properly i suppose? amidst chaos i dont think many can comm perfectly

Because the pros pull their voices loud in order to hear clearly, turning down the volume or switching it off after they die can restore their ears and clearer communication
