Regular earphones direct EMF directly into the brain due to being inside your ear. These earphones block all EMF radiation exposure to the ear and brain. Made using advanced airtube technology, the speakers are situated halfway up the cord where holo tubes direct the pure sound waves to your ears. People around you cannot hear what you're listening to so it's ideal for listening to music and handsfree phone calls. They are also ideal for the Healflux Custom Frequency Generator V2 as they transport the frequencies as pure vibrational sound waves to your ears.
