I recently went through the process of buying hearing aids 1) depending on your insurance and if you can get a discount because from ENT's office it is expensive, although when they heard my insurance offered discount through one of the providers, they lowered their price 2) CHECK the credentials of the person selling and fitting the hearing aids. Look for a real audiologist. The Hearing Instrument Specialist is not an Audiologist (they have PhDs even or at least a Master's) . 3) They should be able to do REAL EAR MEASUREMENTS - my first try, they lied about that capacity and I returned the hearing aids since it was under 45 days trial. 4) Dr Cliff Youtube videos are very informative
