Default Anyone having outgoing speakerphone quality problems?

Anyone having problems with the audio quality when using speakerphone?

I have a bunch of people complaining to me about the way I sound on speakerphone. It sounds like I am in a hole and there is a popping/screaching that they hear.

The person I am having the most problems with is on Verizon with a new Note 3.

I thought it might be the HK hack causing the problem but reversing it back to stock doesn't alleviate the issue.
