100+ Head-Fier
I have come up with a solution for not losing the hearing aids. I bought a bunch of semi-hard zippered cases from Amazon that fit in my pocket, similar to http://www.amazon.com/gp/product/B00SFEB3LI but a bit cheaper. I would guess that if you search around on Amazon, you would find a suitable sized one for about $2-$3. I think the ones I got were are $2, and I bought 10 of them. They last me about 4-6 months, and I'm down to my next-to-last one now, so it's been a couple of years.
I keep my hearing aids (when I'm not using them), some spare batteries, and a set of foam earplugs in them. Since that's now an every-day-carry item, I always have a spare set of batteries on me.
As for the headphone problem, I've found that the cheapie on-the-ear headphones (picked some up at Big Lots for $5) work ok. I just wear them so that the earpads are over the hearing aids, not my ears. Works ok, but I sure would like to find a more comfortable solution. I have Resound BTE hearing aids, and they make a remote mic + line-in adapter, but it's over $300, so I have not gone that route yet. Especially since it's about $25 worth of electronics, and I'm not keen on getting gouged.
Frankly I can't wear my behind the ear hearing aids with my over the ear Sennheiser HD600 headphones. Because I use these at home, I just take the hearing aids out and adjust the volume of my amp accordingly.
