The sheer convenience is what got me … discreet with nothing above the ear!
Also, I work by myself so can’t easily take safe impressions of my own ear … not that any sort of in-the-ear would be suitable anyway.
Build quality is not bad for something so small.
The main problem is losing the thing … put it down anywhere and you spend ages trying to find it again! You will certainly need loss insurance!
I’m not sure about the ‘grunt’ available … my loss is mild so I’m not ‘pushing’ the aid.
I suppose I should put it on a test box to check its output … err, maybe not … how would I wire it up???
