Description

Technical Field

[0001] The utility model relates to the technical field of head-mounted headphones, in particular to a head-mounted headphone with a hidden bracket. Background Art

[0002] The headphones are comfortable and use a comfortable headband, which is comfortable to wear. Even if worn for a long time, you will not feel oppressive or uncomfortable, and the noise reduction effect is good. The headphones are adjustable through a hidden bracket. People who use headphones have different head circumferences and ear heights. Non-adjustable headphones make the earmuffs unable to fit and cover the ears, resulting in poor sound effects and affecting the use effect. In addition, the head circumference cannot be adjusted, so the headphones are either tight or loose when worn, resulting in discomfort or easy to fall off. The ear pads of the headphones often touch the ears and rub against the ears, causing the ear pads to be easily damaged. It is not convenient to quickly remove the ear pads of current headphones, which causes inconvenience in replacement. In view of this, in-depth research was conducted on the above-mentioned problems, and this case came into being. Utility Model Content
