Well NaidaUP , that is a first from the NHS… You are the very first person I have heard of with a set of “Spice” aids from NHS Audiology:D Your aids are, Phonak Naida (S)= Spice (UP)= Ultra Power… These would cost you around £3k on the UK High Street, the Nathos are older Tech, they are “Core” aids! So count yourself very lucky;)
Cheers Kev:D
