Some devices seem to have trouble with the tip shape, however!
A simple cure is to obtain the kind of inexpensive headset splitter cable with 3.5mm stereo output plugs for the headphone and microphone separately. I don't believe that splitting them is the issue, but most of them have different shaped tips on the 3.5mm plugs.
I've bought several different kinds from Amazon and they all seem to solve the problem. They're also handy for their original purpose sometimes. There are several different designs and they vary in length, durability and price...
They're also a handy place to insert toroids to deal with rf issues on transceivers..
Here's one I've used:
hope this helps...
