Most types of mobile phone earphones have a stethoscope effect, but the difference depends on the size of the influence. For in-ear headphones, because their mobile phone earphone module needs to be deep inside the ear canal, close to the eardrum, when the mobile phone earphone wire is touched or rubbed by air, its friction noise will be very large. For wall-mounted mobile phone earphones, headphones, their diaphragm is far from the eardrum, so when the cable rubs against air or other objects, the stethoscope effect is not very significant.

(1) Pull the earphone wire close to the playback software upwards, and the best way to reduce the length of the wire is to pull it closer to the headphones, preventing excessive touching and friction, and placing the portable playback software in the chest pocket is more suitable;

(2) Let the wire run inside the clothes or pants, which is also a good way to reduce wire shaking;

(3) Secure the terminal device of the wire with a rubber band or a metal clip, and stabilize the wire to reduce shaking and friction;

(4) Tie a knot on the terminal device of the wire; the tighter the knot, the less significant the stethoscope effect will be.

(5) Wrapping around the ear, for headphones like Bluetooth earphones, this is a very good way to reduce the stethoscope effect. The basic principle is to keep the wire stable when close to the terminal device of the earphones;

(6) The back line, for all types of over-ear headphones, involves pulling the wire up from the back, which not only stabilizes the wire due to chest movement but also conceals the headphones.
