You should probably still use ear pro with a dedicated suppressor without a braked end cap, the reality is that almost Noone does.
Even suppressed gunfire will damage your hearing, the braked suppressor yes it will damage your hearing without ear pro but not anywhere near the ear bleeding concussion of a directional brake.
Yup you could run a lighter much smaller dedicated brake for the benefits they provide but there are tradeoffs with that too(ear bleeding if you take a snap shot without your ear pro).
I've tried both, I like the braked suppressor, to be fair without measuring equipment I couldn't pick the difference in noise as a shooter, but I could definitely feel the difference in recoil reduction (placebo effect maybe but it works for me).
Maybe the direction the ports vent the gas doesn't affect the shooter behind the but ? (stand next to someone using a brake vs behind them you'll see what I mean).
Who knows maybe it is just marketing and I'm a sucker for it, but maybe it's not.
