Hearables to Outsell All Other Wearable Categories


Wearables are increasingly gaining a foothold in today’s society, and they are not going anywhere. A study shows that one in three Americans use a wearable device. Some wearables are more popular than others, though — and right now, hearables are reigning king.

Some reports indicate the global hearables market size to reach over USD 123 billion by 2032.


Hearables: A Short Overview

Hearables are in-ear computational devices that perform a variety of functions. They first came about when device manufacturers realized that people want more than just in-ear pieces that can amplify and enhance sound. Granted, the first few hearables on the market didn’t quite become an overnight hit; Voicebot says that only about one percent of people with wireless headphones in 2018 used their devices’ built-in voice assistants, but times have changed.

As people become more receptive to voice assistants, hearables gained a stronger foothold. A big part of the shift is attributed to the intuitive design of many hearables, as voice commands are easier and simpler to perform than, say, typing on a keyboard. Additionally, natural language processing has advanced, and developers such as Google are using these advances in their new products and software.

On top of these, hearables can access a lot of information, including:

  • Movement
  • Nerve stimulation
  • Blood oxygen
  • Brain electrical activity
  • Skin resistance
  • Stress hormone levels

From there, hearables can then report on everything from mental effort to physical health.

There are three main types of hearables currently on the market: hearing aids, personal sound amplifiers, and headphones or earbuds.

Design Considerations for Hearables

While hearables are forecast to get even bigger in the coming years, there are nevertheless a couple of things to consider in their design and development to make sure that they live up to their promise. Foremost among these are:

Privacy and security. The Internet of Things has redefined connectivity, and hearables are not exempt from their ever-growing scope. In line with this, the industry needs to contend with improving data privacy and security for users, particularly where it concerns the collection and sharing of sensitive data with multiple IoT endpoints.

Physical design limitations. Hearables must be non-intrusive and provide a seamless experience, and many of them still come with design limitations that hinder user experience. For instance, some hearables are too big, have adverse effects with prolonged use, or otherwise restrict full enjoyment in one way or another.
