Another behind the ear Costco's user here.
They were around $1500.
Bluetooth is a godsend to me watching TV. Audio piped right into my ear.
I have to get them adjusted to use with the phone. My old ones worked well but for some reason the new ones aren't the same.
My daughter stayed over last Christmas with her 2 cats.
I took them out on Christmas Eve and sat them on a table. The next day they were gone. We searched all over the room thinking I'd put them elsewhere.
I struggled without them till the following September, thinking the loss warranty(2 years) was up.
My wife called Costco and they checked and said it was a 3 year loss plan, but, there was a catch, I had to pay 1 cent for the replacements.
About a month later my daughter found the original set. They had fallen into her fabric cat carrier, under some padding.
So now I have 2 sets.
I've worn mine under my electronic muffs with no issues.
I charge them overnight and that last all day.
They seem to hold the charge longer when I use the Music program as opposed to the Automatic program.
