Cant hear any garbled voices under masked sub ?

You can't hear them under 5g anymore

Sure you can. I mostly hear them with my headphones or my speakers using the trickling stream. But I also hear the ultrasonic on every decice, so I guess it's just my young hearing which seems to be good.

Put on some bass driven headphones and I guarantee you, you will hear mumbling so clearly that you will be figuratively scared.
On certain headphones voices can be heard incredibly well, even in 5G .I noticed they can be heard on out-of-ear headphones, on earbuds less.
