2, wearing the ear around the side, and using the wire clip, the end of the line is fixed with a rubber band or clip clamped, through the method of stabilizing the line to reduce the sway friction;
3. It is also a good way to walk the line inside the clothes and reduce the sway of the line;
4. Lift the headphone cable close to the player's section. It is better to draw the distance from the earbuds. This reduces the length of the thread, avoids excessive contact and friction, and it is suitable to place the portable player to the chest pocket.
