NHS Oticon Synergy

Hi. I’ve been wearing hearing aids for around 7 years. I went for a review this week and will be getting Oticon Synergy hearing aids in July. There doesn’t seem to be much info on the internet about these and I wonder why. Are they any good? Has anyone used them with the Streamer?

I think it’s because they are new on the market, an upgrade from the opticon zest I believe.
My mother had just got a pair of them, her first pair of hearing aids, she is finding it difficult to adjust and has no reference point to compare.
How are you finding them?
