CES 2024: What’s New in Hearing Aids, Hearables, and Hearing Healthcare Tech

Here's a quick whirlwind tour of the most exciting hearing-related technologies featured at the 2024 Consumer Electronics Show (CES) on January 9-12.
CES Eureka Park

The Consumer Electronics Show in Las Vegas is expected to be attended by about 130,000 people, with more than 4,000 exhibitors and 1,200 start-up companies across 2.5 million square feet of exhibit space. This 2023 photo shows the entrance to Eureka Park which is a hotbed for seeing startups and new ideas, along with innovations often grouped into countries or regions from around the world.

CES never disappoints when it comes to new ideas in technology. The annual Consumer Electronics Show (CES) in Las Vegas on January 9-12 will showcase new hearing devices and hearing-related technology. Over the past three years, over-the-counter (OTC) aids, captioning glasses, and innovations in hearables, processing strategies, sensors for health and fitness monitoring, and components have taken the stage of the CES show floor.

This year, there are dozens of new and established companies with products at CES 2024 that will doubtlessly impact the future of hearing care. Below is a quick overview of what we think are some of the most exciting technologies featured at this year’s expo. Stay tuned to HearingTracker for more about their innovations.

OTC Hearing Aids and Hearables

xMEMS Receivers and Components

xMEMS has announced an innovative reference design for the fast-growing sleep buds product segment that will be available for demonstration at CES 2024. The Skyline DynamicVent technology, which is also being employed in some hearing aids, delivers improved comfort and automatic ambient control using a physical vent and DSP noise detection. Skyline can be closed for superior noise blocking, or opened to vent the ear and reduce occlusion effects. xMEMs will also be showcasing Cowell, reportedly the world’s smallest solid-state micro speaker that delivers superior high-frequency response and clarity, plus a wider sound stage for TWS earphones and hearing aids. Montara Plus, is said to be the world’s highest output MEMS micro speaker, capable of sound pressure levels up to 120 dB at 200 Hz, making it an ideal full-bandwidth transducer for audiophile-grade in-ear monitors and high-end over-ear headphones. See it at: Venetians Suite 29-235.

Graphic explaining how xMEMS Skyline DynamicVent works

The xMEMS Skyline DynamicVent (top) can be situated in the vent of a hearing aid or earbud to control the amount of passive (unprocessed) sound allowed into the ear. Essentially, it acts as a controllable gate: the closed position (bottom left) shuts out the ambient sound and maximizes the processed sound, improving bass tones and streamed music; the open position (bottom right) allows more ambient passthrough for better spatial awareness and reduced occlusion (own-voice) effects.
