I have Resound Vivia 9s and like them very much. They are not bad in noisy environments (I can hear the cashier), but are not perfect either. I do read that Phonac Spheres do well in noisy environments.
I would encourage you to give Bluetooth another try. It can make hearing phone calls and the TV very reliable/consistent. It can turn On/Off automatically, which makes it very transparent & easy to use.
