HI there - I bought one of these headsets last week - I mostly use it for teamspeak on the PC... i too encountered the "hearing myself" issue... i did find the box to tick to not listen to myself talking the whole time... but it wasn't ticked!! - I ticked it, hit apply, then unticked it again & hey presto - problem fixed.... or so I thought...
Problem is... if I unplug the usb connection, reboot the PC (WIN-7 Ultimate x64) and then plug the headset's USB adaptor back in, the settings revert to to hearing myself (again... the box in Control Panel -> Sound -> Recording Tab is again not ticked, but self listen is active!!
when I check the box & hit apply, i hear myself but with a fraction of a second delay.... VERY off-putting indeed!! then when I un-check the box & apply, its fine...
my issue seems to be repeatable... every time I reboot & then plug the headset, the fold-back or "listen" gets turned on, without the box being checked.
has anyone else had this issue, and resolved it?? or do I send the headset back a PoS? as it is really beginning to upset me that after spending what I consider to be a lot of money, the flipping thing doesn't perform as it should
i look forward to hearing from anyone that has a suggestion.
