Question to Shannon - Quality Earphone

[zen]

Yes, but you know that even Shannon and some users suggested to hear the sub at a high volume - to make the suggestions an urgency or smth similar.

True, but then you're raising both volumes at the same time.. I haven't ever been able to hear the voices, so idk. I can hear the ultrasonic track quite easily so I sometimes wonder if its better to have it louder or not (louder = more urgency, but also I'm more conscious of the audio)

I am listening only ocean surf with extremely cheap/low sound quality earphones, and I raise the volume at around 70% only from my smartphone. I can hear some hidden, unclear voices.

Shannon said once it can be possible to hear some voices with ocean waves in 4G.

So, my question is - the sub is more effective when I hear some hidden, unclear voices or not?
