15-18 hours a day of wear and I hate taking them out at night… I have had a great experience with these aids. Battery life about 7 days, I use the Soundgate, I am on Conference calls all day using Blue Tooth, I listen to MP3 from my phone (DROID) Blue Tooth and watch TV with the adapter included…
My only complaint is the length of time it takes for the HA’s to do their magic and control feedback (milliseconds maybe 1/2 second on occasion) other than that it has been nothing less than wonderful.
Good luck with the trial period.
