Background Noise:

Background noise can be defined as the inherent noise of the front-end device itself, and it has none of business with our earbuds. Background noise comes out mainly because of poor shielding of the front end or because the power supply fails to plug into the ground.

 

So when does background noise come out? If your earphones are of high sensitivity and high sound resolution, then, you need to be careful about the background noise. This is because high-fidelity earphones perform better on sensitivity and conversion efficiency than ordinary ones, which means clearer noise would be received.

 

Solutions:

1. Make sure that the power supply is plugged into the ground.
2. Change the front end you connected.
3. Add an impedance bar to the connected part.

 

About Earphone Improvement:

Earphone improvement, in short, is a process in which the diaphragm continuously vibrates until it becomes steady and in a good position. Some users have responded to us that the sound quality of headphones inclines to change after a period of use. One of the important elements is the driver unit inside our earphones, which can be regarded as a “small speaker”. The other two are the diaphragm and coil. Our diaphragm and coil both adopt thin material and are closely integrated. When the sound signal outputs, the diaphragm vibrates as the coil is energized.

 

The adhesive part of the glue will be affected by slight vibration of the diaphragm. After a certain period of use, the diaphragm becomes more flexible, thus the sound quality is closer to the original desired sound quality when the headphones were designed. The driver unit generally uses a rigid diaphragm.For the time required, we suggest, about 100 hours would be the best. The most vital thing is that we’d better improve the earphone by playback of music we usually listen to. Doing this, compared with a louder volume or pink noise, would be more inclined to make you meet the desired sound quality.

 

Take shoes for example. We always naturally wear our shoes, only hoping they are easier for wearing. Otherwise, wrinkles may be caused. The same is true for the diaphragm, so it is better to let it vibrate naturally than to overtrain it. Of course, you can also do it with the help of software such as QQ Music by turning on the intellect earphone improving mode.

 

Some may be unsatisfied with the improving process just by subjective part. But actually, comparison performs importantly. In another world, we can compare the improved earphone with the ones not, this may convey us a more intuitive feeling. The most important thing is that the suitable sound gradually cultivates instead of short-time be found, and this is true for every earphone.

 

How To Wear:

This series of products are designed as over-ear headphones. When you wear them, please hang the headphone cable on the back of your ears. This is not only conducive for  preventing the friction between clothes and cables, but also conveying more enjoyable wearing.

 

1. Confirm the L and R markingson the inside of the headphones. L is left and R is right.
2. Hang the headphone cable forward from the back of the ear and insert the headphone into the ear.
3. If the headphones are difficult to be fixed and placed in the ear cavity, you can try to gently pull the earlobe back and up, and insert the headphones at the same time.

 

※ If the headphone cable is not easy to adhere to the back of the ear, we recommended to use the harness block of the headphone cable, which may help you fix it.
※ If you feel a little loose, please try other sizes of silicone earbuds. It’s normal for your to wear. This is because our left and right ears are not the same shape, so there will be some differences in size.

 

Precautions of Replacing the Headphone Cable:

The MMCX cable removal clip exerts force on the MMCX connection in the correct direction, which can easily separate the headphones from the headphone cable. It can also avoid the breakage of cable caused by improper force when replacing the headphone cable.

Usage: please align the clip part of the MMCX cable clamp with the junction of the MMCX interface to apply pressure.

For usage, please refer to the linked video:

The headphone cable interface is not specially designed for repeated insertion or removal, because it will damage the interface, resulting in poor contact and other situations. If the headphone cable is broken, it is necessary to update or replace the headphone cable sold by our company. Otherwise, please avoid inserting and removing as much as possible.

To prevent damage to the socket of the headphone, please make sure that the socket remains vertical to the headphone body when installing and removing the headphone.

Please do not pull when removing the headphone cable. Be sure to use the MMCX cable removal clip attached to the product.

Please refer to the content above for usage. The grinding and damage of the pins caused by overuse will be regarded as man-made damage even during the warranty period.
