Apple Earpods inline mic works on computer but not with iPhone 6s

Just recently the inline mic of my apple earpods has stopped working with my iPhone 6s. Other headphones’ inline mics will work, and my earpods’ inline mic works with my computer for web conferencing calls. I checked/cleaned the jack and it’s free of lint. Any idea if there’s a setting that can be corrected or is this just a bizarre anomaly and I need to get new earpods? Thanks!
