✅ The headphones offer 3-fold protection against electromagnetic radiation at the head. ✅ Including: 3.5mm plug/USB-C adapter FREE. So the headphones can also be used for most phones. ✅ The headphones have earplugs with a non-magnetic sound chamber. ✅ There is no speaker in the earplugs, and the brain is not damaged by EMF radiation. This means that there is no magnetic field in the earplugs. Our eardrums are protected and effectively shielded against radiation because the radiation cannot reach the earpiece through the air tubes. ✅ The air tubes have a good function of isolating radiation. ✅ In addition, the twisted and braided structures of the copper wires prevent the transmission of electromagnetic waves along the wire.
