More xMEMS earbuds coming soon?

New reference designs from xMEMS could lead to wider availability of MEMS silicon driver technology.

Published onJune 4, 2024

xMEMS Harding render.
  • xMEMS has announced two new reference designs available to audio brands to accelerate the time-to-market of MEMS silicon micro speakers.
  • The first unit is a true wireless earbud design known as Harding.
  • The second unit is an IEM design known as Montara Plus.

There are very few earbuds currently available on the market that feature MEMS revolutionary driver technology, but that might be changing soon. With the announcement of two reference designs, it’s now easier than ever for manufacturers to leverage xMEMS patented designs. We were very impressed by the sound quality of the Creative Aurvana Ace 2, which are the only MEMS earbuds we’ve had our hands on so far. With today’s announcement, we will hopefully see an influx of more earbuds featuring MEMS silicon drivers in the future.

The first design is known as Harding, and is xMEMS reference unit for true wireless earbuds. Harding features the xMEMS Cowell, the world’s smallest solid-state microspeaker. Cowell is paired with a 9mm dynamic driver woofer in the unique dual-driver system. The earbuds also support ANC and a Qualcomm Bluetooth Audio SoC for a turn-key ODM design.

xMEMS Montara Plus.

The company also announced Montara Plus, which features the world’s highest output MEMS microspeaker in an IEM reference design. These earbuds are capable of sound pressure levels up to 120dB at 200Hz. It’s a single-driver system that promises a fast transient response with a wide bandwidth up to more than 40kHz. The earbuds have a USB-C cable with an embedded DAC from Synaptics and a voice microphone.

Both reference designs are available for purchase for $988.
