Query: Do not buy

This is the second set I bought on Amazon as replacements for my mom's TV Ear system. And it's the second set that didn't work. The first had unusable amounts of static and this one will work WHEN IT IS IN THE CHARGING STATION but not when you remove it--even after a day of "charging." Junk. I am going to the local electronics store where I purchased the original unit and buying it there. I'll return this to Amazon.
