Like many professional scribblers, I sometimes have to write not in a hushed study or library, but in noisy environments. So years ago I bought a set of Apple AirPods Pro, neat little gadgets that have a limited degree of noise-cancelling ability. They’re not as effective as the clunky (and pricey) headphones that seasoned transcontinental airline passengers need, but they’re much lighter and less obtrusive. And they have a button that enables you to switch off the noise cancellation and hear what’s going on around you.

I remember wondering once if a version of them could also function as hearing aids, given the right software. But then dismissed the thought: after all, hearing aids are expensive, specialised devices that are often prescribed by audiologists – and also signal to the world at large that you are hard of hearing.

But guess what? On 12 September, I open my laptop, click on the Verge website and find the headline: “Apple gets FDA authorisation to turn the AirPods Pro into hearing aids.” The new generation of the headphones will be able to serve as clinical-grade hearing aids later this autumn. More importantly, they can be bought over the counter (OTC in the lingo of the healthcare industry) and they will sell for $249 in the US (and £229 in the UK). Compare that with the prices of hearing aids sold........
