1. A retractable headphone connection structure, comprising:
a first connection support, the first connection support having a plurality of first magnetically attractive portions arranged at intervals in a slidably connecting direction; and
a second connection support, the second connection support being slidably connected to the first connection direction in the sliding connection direction and having a second magnetically attractive portion;
wherein the first connection support and the second connection support relatively slide to make the second magnetically attractive portion slide over the plurality of first magnetically attractive portions to generate a magnetic attraction force between the second magnetically attractive portion and one of the first magnetically attractive portions that is opposite to the second magnetically attractive portion, and the magnetic attraction force positions the first connection support and the second connection support;
wherein the first magnetically attractive portion or the second magnetically attractive portion comprises at least one magnet, and a disposition position of the at least one magnet in a direction perpendicular to the slidably connecting direction is user-adjustable;
wherein the at least one magnet is fixed in a recess, a removable spacer is disposed between the at least one magnet and a bottom of the recess, to adjust a disposition position of the at least one magnet in the direction perpendicular to the slidably connecting direction, and the removable spacer is non-magnetic.
