Hello. I have a question to my T family. on this site : http://www.generalfuzz.net/acrn/ computer volume : 30% website volume : 40% (bit small sounds) tested : side by side ( first plug left ear and hear on right ear, second plug right ear hear on left ear) I can hear 12000hz on normal position. but If I turn my neck at an angle of 45 degrees(some specific degrees) I can't hear 12000hz sounds. However, I can hear low-pitched sounds(1 to 8000hz) even if I turn my neck at an angle of 45 degrees. Is this normal or not?
