‘Wireless Earbuds’ Can Listen To Music, Take Calls, And More!


NXP has unveiled new wireless earbuds for the emerging hearables market. The products feature the firm’s NFMI (near field magnetic induction) technology which helps to eliminate the last wire between earbuds (the one between the left and right earbud for Bluetooth headsets). The tech is optimised to design small wireless earbuds or hearables with long battery life, great sound quality and reliable wireless experiences.

NXP’s MiGLO solutions leverage NFMI, an ultra-low-power wireless technology used to sync wireless earbuds together. This helps them stream high quality audio ear-to-ear at less than 4mW. The firm aims to enable uninterrupted audio listening for a full day from a small battery without recharging.

These solutions are specifically optimized for wireless earbud applications and reduce the size of the end product with their Wafer Level Chip Scale Package (WLCSP) requiring a minimum of external components.

MiGLO NFMI solutions are smaller than 11 mm2. With low power consumption, the earbud battery can be significantly smaller for the same battery life. In addition, unlike other wireless solutions, NFMI is designed to work accurately even if earbuds get smaller in future.


MiGlo NFMI, says the firm, provides wireless ear-to-ear connection without signal dropout and without using much power. So users will notice uninterrupted sound, while experiencing extended battery life. In addition, Low latency audio transport in NFMI maintains lip sync. NFMI also tightly controls left and right audio synchronization which allows to maintain the stereo image.

Talking about the new solutions, Asit Goel, senior vice president and general manager at NXP said, “NXP has been providing proprietary NFMI technology to the hearing instrument industry for nearly a decade. NFMI has proven to be a reliable and safe solution to wirelessly stream audio and data ear-to-ear in a medical product that is extremely demanding in terms of power consumption and solution size.”

This Design Helps In Creating Screen-less Displays

Here’s what some earbud designers talked about the NXP’s MIGLO reference designs and chip solutions:

  • “Skybuds are the pioneer in using NFMI in earbuds, we want to offer our customers the gold-standard in audio quality with uncompromised connection. With NXP MiGLO featured in our Skybuds, we are confident we are delivering on this promise,” said Jamie Roberts Seltzer, CEO and co-founder, Alpha Audiotronics. “We chose NXP because they’re also innovators and can meet our quality standards. But just as importantly, we share a similar vision with NXP – to deliver uncompromising audio – and that’s important to our customers.”
  • “We needed a proven solution to handle the unique constraints and requirements of building an in-ear computer, and NXP’s track record as an industry leader in NFMI made them a natural choice,” said Noah Kraft, CEO and Co-founder at Doppler Labs. “With Here One, we’ve built a first-of-its-kind product that does much more than just stream music, and NXP proved to be the perfect partner, helping to ensure MiGLO works seamlessly, not only in and of itself, but also within our overall system architecture.”
  • “We adopted NXP’s technology to deliver flawless audio streaming at lowest power consumption in The Dash. Our upcoming product, ‘The Headphone’, will use NFMI as well to support high quality audio listening for up to six hours,” said Nikolaj Hviid, Bragi CEO.
  • “Thanks to NXP MiGLO our earbuds have the potential to be smarter with features more commonly associated with computers, not headsets,” said David Cannington, Co-Founder at Nuheara. “Nuheara’s new earbuds featuring MiGLO offer advanced speech amplification and dynamic noise control – opening the door to new applications and user experiences that can run on earbuds.”
