@ MVclyde no acoustic neuroma I hope! ( symptoms I had before I found out I had that tumor )... once it came out it only got a little better... still stumble sometimes and run into door frames if I am too close and/or its too dark, cycling has been a challenge with some intermittent weaving, but all in all pretty good lately.
If you slip on sand or gravel, you don't want to land on your head with the baha in place. For HA wearers or CI wearers like me, all we hear is the wind hitting the microphone, which is annoying and masks all other sounds, so there is no point in wearing it. Plus, hearing aids are $2K apiece, and CI processors are $10K apiece, something else to consider.
