Ack. If such a device could be worn on HIKES to HEAR folks all strung out in a single-file line I’d buy one tomorrow. I just have to slap my forehead at the companies trying to make money off us without TALKING to us. TALK TO ME. I will tell you that what we need is a flexible material aid (soft, forms to the ear canal), comfortable enough to wear 24 hours, with perfect seal, POWER, and clarity. You can’t make that yet? Then get lost.
Sorry for my jaded reply, but really.
Minor aside: that neck ring is YUGE as our prez would say. I like to choose my own jewelry for the day.
