Using 2 5G instances (Sort Of)

[AfzalG]

Playing two instances of the same 5G program will overload your brain and result in wasted time and energy.

You will gain more benefit overall from an hour or two of headphone use, but if it's going to cause problems, just loop it on speakers.

what does it mean ? 2 hours on headphones are more effective than several hours on speakers ?

For me speakers seem to be more effective also because i can listen to a much higher volume of the ultrasonic track...
