I wish this help you Detecting changes of this kind is possible by using the IMMDeviceEnumerator::RegisterEndpointNotificationCallback method.
As you want to handle this in C# you will need a managed wrapper which has already been implemented by Akos Mattiassich. You can find a thourough example here: Managed Wrapper around MMAudioDeviceApi

Hope this helps You can observe changes using the CoreAudio framework.
Both headphones and the speakers are data sources on the same audio output device (of type built-in). One of both will be on the audio device based on headphones being plugged in or not.
code :
AudioDeviceID defaultDevice = 0;
UInt32 defaultSize = sizeof(AudioDeviceID);

const AudioObjectPropertyAddress defaultAddr = {
    kAudioHardwarePropertyDefaultOutputDevice,
    kAudioObjectPropertyScopeGlobal,
    kAudioObjectPropertyElementMaster
};

AudioObjectGetPropertyData(kAudioObjectSystemObject, &defaultAddr, 0, NULL, &defaultSize, &defaultDevice); 
AudioObjectPropertyAddress sourceAddr;
sourceAddr.mSelector = kAudioDevicePropertyDataSource;
sourceAddr.mScope = kAudioDevicePropertyScopeOutput;
sourceAddr.mElement = kAudioObjectPropertyElementMaster;

UInt32 dataSourceId = 0;
UInt32 dataSourceIdSize = sizeof(UInt32);
AudioObjectGetPropertyData(defaultDevice, &sourceAddr, 0, NULL, &dataSourceIdSize, &dataSourceId);
AudioObjectAddPropertyListenerBlock(_defaultDevice, &sourceAddr, dispatch_get_current_queue(), ^(UInt32 inNumberAddresses, const AudioObjectPropertyAddress *inAddresses) {
    // move to step 2. to read the updated value
});
if (dataSourceId == 'ispk') {
    // Recognized as internal speakers
} else if (dataSourceId == 'hdpn') {
    // Recognized as headphones
}

To fix the issue you can do Actually, yes you can on WP8. It's not an obvious API, but these guys figured out how to do it as long as the phone is running anything above GDR1.

Hope this helps You should be able to use the Win32_SoundDevice WMI class. Here is a sample script that might be a good starting point:
code :
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_SoundDevice",,48)
For Each objItem in colItems
    Wscript.Echo "Availability: " & objItem.Availability
    Wscript.Echo "Caption: " & objItem.Caption
    Wscript.Echo "Description: " & objItem.Description
    Wscript.Echo "Name: " & objItem.Name
    Wscript.Echo "Status: " & objItem.Status
    Wscript.Echo "StatusInfo: " & objItem.StatusInfo
