The wearables market should only accelerate in 2015, and is presenting unique opportunities for niche products that help consumers. The idea of so-called "hearables" will be heavily marketed as companies develop new products that otherwise would have been overlooked.
The hearable market is expected to be valued at $5 billion by 2018 - close to the same figure of the 2014 wearables market overall - according to Wifore Consulting.
"There's some interesting information you can capture through the ear," said Craig Stires, associate vice president for bit data, analytics and software for IDC Asia Pacific, in a statement to CNBC. "We've been looking at things like wrist wearables, but the ear can capture things like oxygen levels, electrocardiograms, and body temperature."
Analysts believe hearables could be especially helpful to boomers, as smart technology could make hearing devices more intuitive.
