Just a counter-point to illustrate that any hearing aid reviews are subjective. A number of years back I has Costco KS 6 aids which were Resound LiNX. They worked very well for me, much better that the Rexton KS8 aids I later got. This week I hope to get my Oticon More 1 aids to replace those.
For me personally, I never really liked the sharp sound of the Rexton aids and, about a year later, an iPhone OS update broke compatibility and Rexton did not release updated firmware. Their solution for losing streaming connection was to reboot the aids. After suffering with that for several years, I am moving on to another rand.
