specsavers advance hearing aids. My mum bought these while suffering from early Alzheimer’s. She could never get on with technology, so they never got used. I have recently found them and the receipts from 3 years ago. Specsavers won’t take them back. Box full of batteries. No idea on prescription, but they can be adjusted for new owner. Cost nearly £2000. Both left and right ears . These previously sold, but the buyer couldn’t find someone to adjust them so asked for a refund. I’ve listed them as for parts etc as unless you know someone who can adjust them for you, they may not work.
