Even by using head sets (hands free), other research reports recommend not to use over extended periods (about one hour) You try using continously for one hour and the change is perceptible in your hearing ability, although it could temprorary. But whether the orginal sensitivity to hearing is recovered on stopping usage is yet to be proven
