Poor voice quality when headphones plugged in

I have been using an iPhone 4 as my desk phone. I have some Audio-Technica M30 headphones that I use when talking on the phone. The phone sits about 18 inches from my mouth and everything is great.

I recently got an iPhone 6 plus to use as my desk phone. Same headphones, same positioning. Terrible sound quality for the people at the other end. I can hear them just fine.

Played around a little, it has something to do with the headphones being plugged in. When I'm on speakerphone, or holding the phone up to my ear the sound quality is fine at the other end. It is only when I have the headphones plugged in that my voice gets electronic and choppy and sometimes drops beginnings of words.

Any ideas what is happening here? Any suggestions on how to fix it?

Update (09/16/2016)

Just to clarify, it is the voice quality of the microphone as heard by the person I am talking to that degrades when the headphones are plugged in, not the voice quality I am hearing, what I am hearing is crystal clear.

Get a qtip and get off some off the fuzz. Clean the headphone port with it.

The headphones likely have a built in mic. Try to go on a phone call and tap both mics on the phone (one next to headphone jack, and one next to camera) If they can't hear either, then you know the headphones have a mic

The headphones have no mic. The people I'm calling can hear me, but staticky and the beginnings of words (and sometimes whole words) are missing.

it might just be the carrier, some carriers are worse than others when it comes to voice quality

That was my first thought, but I tried different setups and the voice quality was fine on speakerphone or with the phone to my ear, but neither of those is a functional solution for my workflow. I would rather change phones than workflow. But best of all would be keeping this phone and my workflow if I can find a way.

well I'm stumped! sorry!

Thanks for taking a swing at it, I at least felt better that I had been thinking the same things.
