Windows 10: I can hear with my headphones, but it won't recognize my microphone

First off, I've tried to disable/enable my headphone in my desk manager (link is a screenshot)

Then I noticed that the computer recognizes my headphone as a speaker (?) but when I try to switch it up, I can't hear sounds at all, and still can't speak.

Please advise,

Microphone not recognized

I did that before and I did it again and it says it detected a problem and fixed it but it still won't recognize back jack. This is going to show how dumb I am but I just noticed there is a jack for the microphone on the front of my Dell. Windows has been
showing a microphone but said it was on a usb port so that was why I was ignoring it. I plugged the microphone into the front jack and although I didn't hear anything when I talked into it, I brought up the sound recorder app and it did record in it, so I
know the microphone is working. Still don't know why it won,t recognize back jack but not going to worry about it.

Thanks for responding.

 

Hearing headphone microphone through headphone speakers

I have got some Sennheiser 4.40BT headphones. When I connect them to my laptop (Windows 10) through bluetooth, then enable the microphone, all sound that goes through the microphone gets relayed through the headphone speakers. It makes everything sound very echoey and I can hear the smallest of sounds really loudly (it's like I've got a super power). If I connect the headphones to my laptop through a cable I don't get this issue.

How can I stop the sound going through the microphone being relayed to the speakers?

 

Headphone no longer working as intended. I use no speakers, solely the headphones. I can only hear if I set "Speakers" to default. Headphones being set to default results in no sound at all.

The previous 2 lead to nothing however when I went onto the 3rd step and attempted to set up a microhpone, immediately the PC broadcasted on screen "Detecting Problems" followed by a "Whats not working?" with the two options being "Cortana can't hear me"
and "I can't hear Cortana". Selecting the "I can't hear Cortana" leads to a list of devices to troubleshoot. Troubleshooting the "Headphones" while they are set as the default leads to nothing. Troubleshooting the "Speakers" allows for the headphones to broadcast
noise.

Do I need to proceed to the other options or does my problem have to do with step 3?
