How to choose headphones

Choose headphones according to sound quality.

Sound quality must be the soul of an earphone. No matter how perfect the appearance is, no matter how good the workmanship is, it is also a cloud without good sound quality. Sound quality is a very subjective standard. Everyone has different preferences and different evaluations of sound quality. In this regard, it is the most reliable to choose products with appropriate prices and appearance that meet your own requirements in e-commerce, and then go to the physical store to audition and buy.

Choose headphones according to the usage scenario.

Headphones can be roughly divided into three types: wearable headphones, in-ear earplugs and flat-headed earplugs.

Headphones: according to the sound insulation structure, they are divided into open, semi-open and closed. The natural sound quality is good, but the sound insulation is poor. Not only the wearer can hear the surrounding noise, but also the people around him can hear the music played by the wearer. Many high-end models are open, such as Senhai hd650, akg k70 1 and so on. Semi-open and closed sound insulation will be better. For example, akg k450 is half open and Boya dt 1350 is closed. If you want to see things in the dormitory without affecting others and don't want to be influenced by others, it is recommended to choose a closed type, or you can choose a model with noise reduction.

In-ear earplugs: Compared with portable headphones, the sound insulation effect is better. The disadvantage is that there may be a stethoscope effect. Generally speaking, the stethoscope around the cord and ear has little effect. The model with heavy stethoscope effect is not suitable for exercise. However, this sound insulation advantage is reflected in the crowded subway and bus.

Flat head plug: the advantage is that the stethoscope has little influence and is easy to carry. Disadvantages: the sound insulation is the worst, the sound is unstable, and the elastic sound worn will be different. Belong to a more moderate choice.

How do college students choose headphones?

Choose headphones according to personal physical conditions.

Headphones are divided into ear-wrapping type and ear-pressing type according to the way of wearing. Ear wrapping is to wrap the ear like k70 1 above, and ear pressing is to press the earphone on the ear as the name implies, such as k450 and dt 1350 mentioned above. Some people can't wear ear pressure because of their ear shape or head shape. You must try it.

In-ear styles have different calibers, and people with small ear holes will feel pain when wearing large caliber. For example, the models of Intemet and Weston are narrow-mouthed, while some models of ue are abusive.

Select headphones according to the playback device.

I believe that most student users use mobile phones or iPod walkman as players, and these products themselves have little thrust. When purchasing, you should pay attention to that some headphones with high thrust may not be suitable for your own playback equipment. If you don't know much about this, it is also recommended to go to the physical store for audition!
