Query: Good sound, but weird echo for everybody else on voice chat

This one is a good headset. More or less comfy on my big head. Sounds are great and loud. There is only one thing I am confused about - when I am on a voice chat (any application), everybody else hear their echos. I do not hear any echo, not mine, nor theirs. But everybody else do. I have no idea what is causing it. I only know that if I switch to my old headset, no echo for anybody anymore. Hence It's good for gaming and music only for me now.
