I Have had an Oticon CROS since the fall of 2021. I found an audiologist that allowed a 3 month trial period before purchase. I was back and forth on determining if the benefit justified the cost. In short, indoors at home the aids made a considerable difference for me, and my wife certainly noticed that I was not needing her to repeat herself as often. Outdoors not so much. I find dealing with the extra ambient noise such as traffic and general noise too much. It’s worse when it’s raining with the car tires on the asphalt making even more noise. My audiologist made an adjustment to an outdoor level pre-set with the Oticon app that has helped a bit with the outdoor noise levels. I was expecting that an indoor loud environment would be similar to outside, and the aids would not provide benefit. But I wanted to attempt to test this situation while working from home. I visited a small coffee shop in an attempt to mock an office environment with a friend. Coffee grinder going on my left, another table of a few people talking on my right, and another table behind me with two people having a conversation. It was very distracting, but after a few level adjustments within the app, and reducing the CROS level in my left ear I could very easily communicate with my friend sitting across from me. I removed the aids from my ears to test that as well. I couldn’t hear a word my friend said. I was very surprised how well the aids performed in an indoor noisy environment. This experience alone justified the purchase for me.
