Pro reviews: What works for some people doesn’t necessarily work for all, and we know there are tremendous variations in people’s hearing loss, dimensions of hearing canal, etc. ‘Pinch of salt’ is a great metaphor, though ‘pound’ may be more appropriate that ‘pinch’.
My bet is that pros who review objectively know one size doesn’t fit all.
True, but 1st he should have some idea of which brand he wishes to trial, imho.
Many pros argue that the brand matters less than the skills of the fitter, I’m pretty sure that buying a brand is not the best approach, especially since manufacturers sell under so many brands.
Remember: branding aims to benefit sellers, not buyers. Branding just aims at getting buyers to buy without thinking critically.
