Then, the user applies a certain amount of force to pull the dust cover 16 outwards. When the dust cover 16 moves, the third annular magnet 17 and the fourth annular magnet 18 lose contact, thus losing their magnetic attraction. This completes the removal of the dust cover 16. The user can then place the replaced dust cover 16 into the mating ring 9 and bring the third annular magnet 17 and the fourth annular magnet 18 into contact for magnetic attraction. The attraction between the magnets fixes the ear pads 14 and 15 within the docking ring 9. The replaced ear pads 14 are then placed inside the docking ring 9, and the first annular magnet 12 and the second annular magnet 15 are brought into contact, attracting each other magnetically and fixing them within the docking ring 9. After replacing the ear pads 14 and dust cover 16, the user can attach the docking ring 9 to the inner side of the docking cover 3 and align the fixing block 10 with the through hole on the docking cover 3. During the placement of the fixing block 10, it will press the wedge rod 8 downwards. As the wedge rod 8 moves, the spring 7 is compressed. When the fixing block 10 moves to a certain position... The fixing block 10 will no longer press against the wedge rod 8, and the spring 7 will drive the wedge rod 8 to reset. The wedge rod 8 will move into the wedge groove 11 and engage with it, so that the fixing block 10 can be fixed. After the docking ring 9 is placed, the replacement of the ear pad 14 and the dust cover 16 is completed. When the user uses the headphones, the fan 19 can be turned on. The fan 19 blows air through the air outlet to the user's ears, which can prevent the user's ears from feeling stuffy and sweating during the wearing process. The sound-absorbing plate 20 can absorb sound during the use of the fan 19, which is convenient for the user.
