Echo when using HS65 on the other end

[moguy1973]

I have bought my daughter a pair of HS65 Surround headphones and when we are playing games together I can hear myself talking through her headphones.  I've tried adjusting volumes and mic settings and I can still hear myself.  Is this just a problem I'll have to live with when she's using these headphones?  It makes it really hard to talk in voice chat due to the delay that exists.  I wouldn't think there would that much bleed through from the ear cups to the microphone to make this happen.   If so, it's a very poor design.  I've never had this happen on any other headphones I've ever used. It goes away when I push the boom mic up to mute it so it does seem the sound bleeds through somehow to my end.  This is being used on a PC and it happens for all games using voice chat.
