Subliminal Talk

is bluetooth speakers/headphones okay to use for subliminals? (specifically sleepphones wireless)

here is the specs:

TECHNICAL SPECIFICATIONS:
Bluetooth® 3.0 Type A2DP
Wireless Range: 15-30 feet (5-10 meters)
Battery Life: 8-12 hours
Battery: built-in lithium-ion, rechargeable via micro-USB
Speaker frequency: 20Hz - 20kHz

I have the current Wireless Sleepphones (it should have longer battery life). They work. CatMan used them extensively and I'm using them as well. Just make sure you have your music player somewhere equal to or maybe slightly higher than the height of your bed. I've found that if it's lower, it's likely to disconnect in the middle of the night, but not at the same height.

See that frequency response? That's what you need. And it's there.
