I’ve used the Nuheara IQBuds Boost for a number of years. At the time I bought them (€400) I was being quoted €4,200 for a pair of digital hearing aids that I tried for a bit. Once I tried the IQBuds, I found them very helpful for my situation, and couldn’t see enough difference to warrant the much greater (x10) expense.
Over the years, they’ve worked very well. However, a particular issue is worth noting. They amplify sounds, albeit at different levels to suit their on-board NAL/NAL2 ‘prescription’. This gives rise to a huge problem with often really painful amplification of short, sharp high-freq sounds, such as a closing door, a cup being placed on a hard surface, clinking of glasses in a bar. This issue may well have been resolved in the later product IQBuds2 Max. I haven’t tried those.
For anyone who is HOH, these types of solution are well worth a try, if the alternative is to soldier on in a world of mumbles and “What?”. That said, its likely to not be a long term solution, as for most people whose hearing will disimprove over time, they just wont cut the mustard for serious sound processing.
I note that HP has recently entered into a licencing agreement with Nuheara for the latest version of their product. These have obtained CDC clearance as a medical device in the OTC hearing aid space. I understand they will retail at $699 in the USA.
