I don’t have a lot of experience, but, so far, I’ve worn my HI Health Innovations BTE aids for about a month and I definitely get noise interference between my aids and my glasses. It’s as if the glasses are “live” and any movement of the glasses causes a brushing sound with the HA mics. I even occasionally get a sound with movement of my glasses and the HA’s when I’m walking. I figure I would eventually get used to the sound, but I was glad to see when wearing a trial set of the Costco KS7’s, I didn’t have the same problem. I have a pair coming in about 10 days and I’m hoping they won’t interfere with the glasses. I didn’t wear my HI Health aids to the Costco appointment, so I couldn’t compare size, but I think the KS7’s might be just enough smaller to avoid the sound interference. I hope so. I’m not about to lay out $400+ for a new pair of glasses unless my prescription changes.
