Why can’t the Audio Industry be more inventive?

The audio industry is constantly telling us how great its products are. Their latest wheeze is to push the message that we all need even higher quality. That’s despite the fact that nobody can hear the difference. Unfortunately, the major players so believe their own PR that over the last century they’ve largely missed the fact that there’s more to the listening experience than just extending frequency response. On the few occasions we’ve seen real innovation in audio, it’s almost always come from outside the established audio industry. So how do we put innovation back into audio?

What’s next for Apple and hearing aids?

It’s around a month since Apple received approval from the FDA to sell their AirPods Pro 2 as hearing aids. That announcement caused a flurry of excitement amongst audio industry analysts and journalists, predicting that it would change the hearing aid market. I suspect that may prove to be false. The more interesting debate is whether it will lessen the stigma which is still associated with wearing a hearing aid. Andrew Bellavia and Joao Martins have written well-considered pieces on this. It’s a topic which needs more consideration than the media’s obsession with the technology or manufacturer, as it’s still unclear how we can change society’s attitude to hearing loss.

Bluetooth and Auracast are changing the way microphones are designed

Most people have a view about their speakers, earbuds and headphones. They’ll happily enthuse about the audio performance, how well the noise cancellation works, their battery life and features like transparency. But nobody talks about microphones. The most you’re ever likely to hear is an exasperated “can you hear me” during a phone conversation, or a possibly muted oath about whether they’re muted and how to turn the mute on or off.

Will 2024 be the year of Apple’s Vision Pro or Bluetooth’s Auracast?

It’s almost wo weeks since Apple shipped its first tranche of Vision Pros to around 100,000 lucky boys and girls (although I suspect the majority were lucky boys). According to the New York Times, the average cost of a Vision Pro is close to $4,600 by the time you’ve fitted it out with the recommended accessories. If you’re outside the US, there’s a significant premium on top of that. So, the first tranche of sales of around 200,000 units will have netted Apple in excess of $1 billion. That’s a staggering achievement, as is folding all of the tech into the product. Bringing it to market is an amazing step. The question is whether it’s going to impinge on very many people?

Auracast and the Evolution of the Earbud Case

Sometimes, it needs what seems to be a small, tangential innovation to make a product successful. At the time, it may not seem much, but it can result in the product acquiring a life of its own. One product which is making its way along that trajectory is the humble earbud charging case.

The history of the charging case is quite interesting. Stereo wireless earbuds were a long time coming. It needed some serious technical innovation by a couple of chip companies to make them possible – new technology by Cambridge Silicon Radio (now part of Qualcomm) to let them receive and render separate left and right audio channels, and small near-field magnetic induction chips from another silicon company – NXP to send wireless signals through our heads. It then needed the brilliance of a German startup called Bragi to turn these concepts into working stereo earbuds, kickstarting the whole hearables market. It has become the fastest growing technology product ever, eclipsing even the iPhone in its growth.

Introducing Bluetooth LE Audio – the book

Just before Christmas, the Bluetooth SIG published the final documents in the first release of Bluetooth LE Audio. It’s been the largest single development in the history of the Bluetooth specifications, taking around eight years and comprising 25 new or updated documents, with over 1,250 pages of specification. Its aim is ambitious, the intent being to provide the platform for the next twenty years of wireless audio development.
