I got new Jabra hearing aids at Costco, and the left one makes crackling noise at all high frequency noises. For example, when two pieces of silverware clink together or water in a tap first hits the basin, etc. This only happens in the left ear. I wore Oticons for around 10 years, and never had this happen at all in either ear.
Is this a matter of the adjustment being set too strong at the very high frequencies, or is the left defective?
