well have had mine for about a month now (Oticon Acto) and for the last 2 weeks have been wearing them for over 8 hours per day, I often forget I have them in, so at this stage I am very happy with them, the wife likes that I can now hear her when she says something but is complaining that I talk too softly (us blokes cant win) as for the tinny sound I experiance this and went back had them adjusted and now fine, it certainly makes a difference when hearing running water or paper rusteling I also heard a new rattle in the tug and cannot find it so might have to take aids out when driving or turn the volume down.

Thanks again to all those who answered my last post on this topic
