Need help with Blue Yeti Microphone?

I recently purchased a Blue yeti microphone, and have been using it on my Iphone with a lightning to usb connector. All was working fine until the other day, usually when I plug my headphones into the Blue Yeti I can hear myself talking but for some reason it has just stopped doing that. The microphone still does work when i'm recording, but i just can't seem to hear it when i have my headphones in anymore?

If you can help me out, you are amazing!

Ok, I think blue yeti microphone is good, but those are electronic devices so don't know what happen with them…

If you tried powering down the phone and disconnecting and reconnecting the mic and that did not fix it it might be time to try a new Yeti mic. If the new one does the same thing then at least you can return it. Try connecting the old mic to a computer too.
