1. Check whether you turned down the volume by accident.
2. See if there is anything dirty at the socket, and clean it if there is.
3. Turn the earphone plug and listen to whether the volume has changed. If there is, it is the contact problem at the interface. You can try another earphone.
4. Some sound plug-ins are turned on, so the volume is reduced. Close some background programs and have a look.
5. There is something wrong with the headphone cable. If the line is broken or the contact is not good, change the earphone.
Ring iron mixing:
Ring iron earphone is a kind of earphone driven by moving coil and moving iron. It has the structure of single moving coil+single moving iron and single moving coil+double moving iron. The moving iron unit has the advantages of high electro-acoustic conversion efficiency and light vibration body, so it has high sensitivity and good transient performance, which highlights the dynamic and instantaneous details that music is difficult to express in the original moving coil.
The low frequency and intermediate frequency are naturally presented by the moving coil unit, which gives full play to the advantages of good ductility, full intermediate frequency and natural transition of the moving coil bass. The advantages and functions of moving iron unit mainly undertake and supplement the high-frequency attenuation part of moving coil. Starting from the frequency division point of 6kHz, the moving iron unit is responsible for high frequency and extends the high frequency range to 30kHz.
