Ex electronics / audio engineer / musician. I now have no useful residual hearing. Unsatisfied with NHS efforts producing good sound level but high distortion. I purchased qty2 Lotus 12SP on line and then used Hearing Direct for tubes and domes to suit. Have used these now for 1 year. Spectrum not quite right (different for each ear) the brain tends to correct for that, but there is no objectionable distortion. Originally I thought that if the experiment didn’t work, I wouldn’t have spent a fortune. It did work, and your help with supplies has been appreciated.

After fitting the replacement tubes to my aid I found that they conducted the audio from the aid to my ear perfectly. Exactly what I hoped so entirely satisfactory.
