People who often wear headphones to listen to music should master a "60-60 principle", which is also an internationally recognized method of hearing protection. When listening to music, the volume should not exceed 60% of the loud volume, and continuous listening should not exceed 60 minutes. Here we take a look at the long-term use of headphones, headphones purchase tips.

3. For walking, cycling and other sports with a small amount of activity, users can wear ordinary ear headphones. Remember to get an earplug on the earbuds to prevent the earphone rubber from aging. It is also good for the ear and the headset can be cleaned. At home, it's better to wear a heads-up type, because the movement is more, one will sit, one will stand, and there is something to do housework to prevent the line from being deadlifted. Special attention should be paid to listening to the bed, if you fall asleep, accidentally turned over, it is easy to crush the headphones, or turn the body when the ear and lead to pull the ear break.

4. After the headset is used, it cannot be “rolled” on the player. It should be placed in the box or bag that the headset supports. If it is a headset, it can be stored using a CD-sized bag, which, to some extent, also prevents the headphone casing from being scratched. Better put a desiccant to prevent rubber aging deformation.

5. Make full use of the accessories that the headset is equipped with, such as a reel, and some headsets are equipped with a very long (3 meters) cord that can be rolled up with a reel when you do not need to use a long cable.

Headphone purchase skills

1: Use familiar songs as the criterion

What kind of music should be broadcast when testing headsets on the market? Get it right out of your iPod, MP3 player or cell phone. At this time, it is very likely that some friends will have an idea in their heads that "whether MP3 or WMA, all compressed and destroyed digital music files, the sound quality sounds rough, how to use it as a standard for commenting on a headset? "You're right, this theory is completely correct, but what we want to share with you here is the concept of "custom."

Because you often use your own iPod or MP3 player to play your favorite music, so you are completely familiar with the melody of the song, so other conditions remain the same, for another headset, will know this song very clearly The high and low frequency performance of that section is not the same. In addition, each headphone brand has its own sound personality, and some powerful players will advance into the comparative conditions of sound field, space, balance, grain, sound and dynamics. Therefore, it is recommended that you try to listen to a variety of genres, so that you can pick your favorite headphones!

2: It is very important to wear comfortable earplugs and cushions

Did you try to buy a pair of jeans back home without a try because of the cheap price? At this point, it is likely to encounter a dilemma of inconsistent dimensions. This is the same as buying an earphone, even if the tone is no matter how good, if the field audition for a few minutes, the liner is airtight, replaced the earbuds, the size does not meet the ear canal, advise you to give up.

3: The product specifications are better and a little look

The specification on the box is of course one of the keys to consider the performance of the headset, and usually the places of attention include:

Impedance: The lower it is, the easier it is to push, but the higher it is, the worse it is. It does not mean that it is not good, but that the sound quality has another new realm. You need to use a headphone amplifier to drive. Therefore, some audio and video magazines, when describing the headset, will first describe the feeling of listening to the iPod, and then insert the ear and expand to be a professional commentary. Generally, the earphones for iPods or portable MP3 players are mostly impedance 14 ~17 or so, earmuffs headset is slightly higher.

Sensitivity: The unit is decibel. The higher the power is, the smaller the required power is, the easier it is to drive. In general, earphones for iPods or portable MP3 players have an impedance of around 105~110.

Frequency response: The frequency response refers to the frequency range of the sound emitted by the earphone, so we can see the value of the two ends. We can guess that this headset has a deeper ink in that frequency range. The human ear frequency range is 18Hz~20kHz.

SNR: The higher the SNR data, the less noise is heard.

4: The new headset will be better

Many people say that “what it takes to take the opportunity” to use this word, according to the Ministry of Education's online Mandarin Dialect, explains: Cooking food with low heat, I think it's quite appropriate to describe Run as opening a headset.

You start with a new headset, please remember to take a week after taking it home, or some customers buy home and immediately call customer service, saying why not so nice in the store, this is because the new headphones, the inside of the winding The coils, magnets, and some crossovers are all new, and most of the coils are made of copper wire. After a period of time, resonant coil push-pull operation is smoother. Of course, you can also use it directly and slowly feel the sound of the headphones moving from a tight state to a good open space. As for me, I like to be in place once and insert it on the stereo continuously for one week, and then plug in the iPod.
