I have hearing aids Michael.
Behind the ear type.
I would wear them riding but, they end up hurting the area(s) behind my ear(s) after a few hundred miles due to the helmet pressure on the device.
Also, the really good devices have a compression circuit that dampens the amplification after a certain db level. While ridiing, I think mostly from wind, but regardless, the noise is enough to constantly be engaging the compression circuit. So the battery life is really shortened. When not riding, I can get three days or more out of batteries. On the bike, maybe a day.
Also, you'll be tempted to buy "cheaper" ones.
I'd advise to spend more.
The more expensive devices can be very precisely programmed to your specific hearing loss IN EACH EAR. But you're looking at $5K or so for the best of the best.
The cheaper ones will have a tendency to feedback more and will be far less tailorable to your specific hearing loss.
I have a buddy who does hearing aid fitting/installation/programming for his living. Has his own business. Is on our state board of examiners for this type of work.
He's taught me a lot.
Like a HD bike, the markup on these devices is A LOT.
Pays to shop around some.
And there is also a Ford vs Chevy thing. In other words, most of the best vendors (Siemens, Starkey Labs, Unitron, others) all offer similar models at various price points.
Does that make sense I hope?
Hope this helps.
As far as riding, especially on long trips, I just leave mine out in the box while riding during the day and put them in at night.
Oh, and I can't wear them at work because I can't get the stethoscope ear buds to seal in my ear canal while wearing the devices. Drives the nurses nuts! Hah? What did you say?
