Because the iPhone is an American product, the international standards made in the United States are different from our national standards, so there will be incompatibility problems.

it can be used normally by adjusting the properties of the computer sound playback device. First, we move the mouse to the speaker icon in the lower right corner of the desktop, and right-click to select the playback device.

2. Then find the iphone headset you inserted in the playback device, and select Properties with the right mouse button.

3. then select the level menu in the headset properties window, and then click the balance button.

4. Then set one of 1 and 2 to in the balance setting, and set the other to normal playback volume, so that the iphone headset can listen to sounds or songs normally.

5. Of course, the above method has a disadvantage, that is, the sound can't be surrounded perfectly. This is something that can't be helped, so I can only make do with it, and it's not much worse.

6. After the above method is set up, you need to test whether the iphone headset can play normally. You can open a webpage to play a piece of music, and then adjust the levels of 1 and 2 to find the balance you like.

Of course, you don't have to do the above settings. Just press and hold the button on the Apple headset to adjust the volume. If you hold and hold it, the sound will be normal.
