Description

Technical Field

[0001] The utility model relates to the field of headphones, in particular to a portable headphone. Background Art

[0002] A headphone usually consists of a headband and two earcups connected to the ears, and they have wide applications in aspects such as music, entertainment, gaming, and communication. The design of this kind of headphone aims to provide a better audio experience and comfort. Headphones usually have elegant audio driver units and noise isolation technologies, which can provide higher-quality, clearer, and more realistic audio performance. When wearing a headphone, one can better feel the details of the music and even distinguish the subtle differences in the mix. The earcups of the headphone can isolate external noise, thereby reducing interference and enabling users to focus more on the content being listened to. Some headphones also have active noise cancellation functions, which sense external noise and generate opposite sound waves to cancel the noise, further reducing the interference of the surrounding environment on the audio. This is very suitable for use when traveling on a vehicle, working in a noisy office, or just wanting to enjoy a quiet environment. This is very important for listening to music, watching movies, or having a conference call in a noisy environment. Headphones usually have an adjustable headband and rotatable earcups to adapt to people with different head sizes and shapes. These functions make the headphones more in line with personal needs and provide better comfort and stability.
