Precautions for purchasing headphones
1.Type
The type you choose can be considered based on your needs and financial ability. Generally speaking, the electric earphone has the characteristics of stable sound quality, simple structure and low price, which is suitable for general people to choose. The capacitive earphone has the characteristics of good sound quality and frequency bandwidth, but the price is high, which is suitable for enthusiasts. .
2. Shape
Because it takes a long time to wear, the earphones should have a very soft and comfortable ear pad and a very low pressure head ring. As for whether to use the earbud type or the cover type, depending on the specific situation, it is always impossible to use a large full-cover earphone cover on your ear on a hot day.
3. Indicators
You can understand the performance indicators in its manual, generally required to reach the minimum, 20-20KHz frequency range, greater than 94db/mW sensitivity, greater than 100mW maximum power, less than 0.5% harmonic distortion and so on. If you do not meet the above requirements, it is best not to buy.
4. Appearance
Judging from the appearance, the authentic headphones have a smooth appearance, fine workmanship, and excellent hand feeling. There should be no rough feeling of using inferior plastic. In addition, the lead wire of the earphone should have a thick wire diameter and be soft and not hard. The plug is required to be standardized and smooth, and the coating is smooth and uniform.
5. Audition
I said so much, but the most important thing is to listen to it personally. This is the most crucial part. When auditioning, try to use a better source of the program to listen to it. Don't use the inferior sound source, because it is not good or bad. If you pay attention to this, I will not say more. The specific situation is only Listen carefully to your ear, and the author can't help you. Who is better and who is inferior.
usage notice
After the earphones are bought back, the earphones are also learned. If the headphones are used improperly, they are easily damaged. The main points should be noted:
1. The plug of the earphone should be commensurate with the size and length of the headphone jack on the computer, and the earphone should be inserted into the earphone-specific jack provided on the computer as much as possible. Do not insert the wrong one to avoid damage to the earphone.
2. The earphones are generally marked with L[LEET] and R left and right channel words to distinguish between left and right. If not, it can be judged according to the color of the headphone wire. Generally, yellow is the left channel and red is the right channel.
3. When listening with headphones, the volume should be gradually increased from small to large, so do not suddenly make the volume large, so as not to damage the headphones.
4. Avoid placing strong magnets when the headphones are placed, so as not to demagnetize the permanent magnets of the headphones, so that the sensitivity of the headphones is reduced.
5. After using for a period of time, the ear pads should be cleaned. Gum foam ear pads can be gently scrubbed with neutral soapy water or detergent. Plastic or leather ear pads can be wiped with damp cloth soap powder. Do not wash directly with water.
