I have spoken to the manufacturers about these aids that appear on ebay etc.
Most seem to be bought by registered suppliers … who then slip them into the ‘grey market’.
Some very low end aids seem to be Third World model BTEs which make their way back to the West.
The Internet aids are often from minor Italian and American manufacturers who supply both retail & Web suppliers. These aids are OK - but certainly nowhere near as advanced as the top retail-only products.
I have no idea where ‘reburbished’ aids come from - maybe dealers putting returns etc into the grey market?
Also, maybe some of these aids have been stolen. For example, I know that many aids disappear from the NHS stock cupboards.
Whatever you think, the major manufacturers are certainly not keen to have their aids swilling about the Web being sold by ‘unusual’ suppliers.
I run a mail order hearing aids parts business … and my supply contracts INSIST that I do NOT supply aids via the Web … just sundries. I would be an ideal outlet for mail order aids for the key manufacturers - but they clearly have no interest in Web aid sales.
However with so many ‘official’ aid suppliers globally it’s no great surprise to see a few aids being sold on the Web etc.
Look this is one dirty business from what I can tell.
Any business has its ‘dark corners’. Why should the hearing aid sector be any different? No conspiracy theories needed.
