Thank you for the reply Shannon! I enjoyed reading your post 
Should I use the ultrasonic version with my wireless headphones or a speaker? I’ve read that ultrasonic works by vibrating the hairs in my ears, but listening with my wireless headphones will send the electric impulses to my brain (as you’ve noted earlier) without any vibration.
This is the most convenient mode of listening for me as I’m usually at school or away from home :p
Also, if it’s possible to listen with my wireless headphones, will the ultrasonic subliminal still be as effective in noisy environments?
