AThe interference intensity is directly proportional to the concentration of negative ions. The concentration of negative ions of EH-100 is very high, which is above 10 million ions / cm3. If the negative ions concentration of other products aren't high , the interference will be very weak naturally. In addition, due to the different conductivity of each human body, there will be different interference strengths.

AThis is a normal phenomenon. The negative ion concentration of EH-100 is more than 10 million ions / cm3. (see the actual test chart as left, It has reached 14.69 million ions /cm3. Due to the high concentration of negative ions generated, the negative ions will float in the air, and our hands are also a conductor. When we touch the volume button of BT, the negative ions will be brought there. When the concentration of negative ions is high, there will be a slight interference to BT, which will produce this interference phenomenon. When the hand leaves, the interference disappears, so there will not affect your normal use.
