Graphene Audio

Researchers from ICFO, ETH Zurich, University of Ioannina, Catalan Institute of Nanoscience and Nanotechnology (ICN2), Arizona State University and Japan's National Institute for Materials Science have demonstrated the first graphene‑based sub‑terahertz (sub‑THz) direct receivers that simultaneously deliver multi‑gigabit‑per‑second data rates, ultra‑compact footprint, CMOS compatibility, and near‑zero operating power - making graphene a valid hardware candidate for 6G wireless communications. 

They operate at sub‑THz carrier frequencies to meet the demanding requirements of future links, achieving multi‑gigabit‑per‑second wireless data transmission over distances of around 3 m at room temperature, with a fully electronic, zero‑bias detection scheme and a device area of only about 0.018 mm².

NACON, a premium gaming gear company and parent of the RIG audio brand, has unveiled its latest release in their R-SERIES of headsets – the RIG R5 SPEAR MAX HD. Purpose-built for PC gaming, the R5 MAX HD features innovative GrapheneQ™ drivers from Ora, setting a new standard for studio-grade game audio.

Custom-tuned for first-person shooters, the R5 MAX HD are powered by Ora’s patented GrapheneQ™ technology. Constructed from pure graphene, the GrapheneQ membrane offers the ideal mechanical properties for headphone speakers. The material’s unique combination of high stiffness and low density allows for improved audio reproduction and ultra-low distortion. In gaming, these qualities translate to improved spatial audio, allowing players to localize sounds and objects with enhanced speed and precision.

Researchers from the Korea Research Institute of Chemical Technology have demonstrated a new class of shape‑configurable thermoacoustic loudspeakers that defy the traditional tradeoff between film thickness, flexibility, and acoustic output. Instead of relying on vibrating membranes, these devices use vertical graphene microstructures to convert electrical signals into sound through rapid heating and cooling, enabling loud, robust, and stretchable audio elements that can be integrated directly onto curved or deformable surfaces.

A core challenge in thermoacoustic speakers is that high sound pressure levels (SPLs) typically require ultrathin conductive films, which are mechanically fragile, difficult to process at scale, and limited in power handling. Thicker films are more durable and easier to manufacture, but they trap heat within their bulk, suppressing thermoacoustic efficiency and causing SPL to collapse as thickness increases. This thickness–performance tradeoff has restricted most previous flexible TA speakers, such as MXene‑based devices, to tens of nanometers thickness, SPLs below 75 dB, and moderate strains around 50%.

Fender Audio, the consumer electronics division of the instrument manufacturer, will present two flagship audio products at CES 2026. Developed under a licensing agreement with Singapore-based RiffSound, the new lineup reflects Fender’s entry into advanced material integration for audio performance.

The new MIX headphones will incorporate 40mm graphene drivers. Graphene’s combination of low mass, high stiffness, and excellent conductivity contributes to greater acoustic precision and reduced distortion compared with conventional driver materials. Fender indicates that these properties help optimize energy efficiency and enhance sound detail across the frequency range.

The Sixth Element (Changzhou) Materials Technology has announced that it has teamed up with brands including Logitech and Corsair to supply graphene materials for over‑ear graphene headphones.

While additional product info is not available, it is known that Logitech already markets a graphene‑driver gaming headset (the G Pro X 2 Lightspeed), which uses a 50 mm graphene diaphragm to reduce weight and distortion and improve fidelity.

LG Electronics (LG) has expanded its Xboom Buds lineup with three new models - Buds Plus, Buds, and Buds Lite - continuing a collaboration with musician will.i.am that began with the launch of the Xboom Buds. All Xboom earbuds incorporate audio tuning by the artist for a vibrant yet balanced sound, according to the company. 

The Xboom Buds Plus features graphene-coated drivers with triple MEMS microphones, which actively reduce background noise during calls and music playback. The adaptive EQ dynamically adjusts the sound tuning for the best sound reproduction, and users can further adjust the EQ using the smartphone app to their liking. The best fitting ear tip for noise reduction can be found using the Noise Cancelling Optimization feature in the app.  They offer up to 10 hours of runtime between charges, with up to 30 hours of total runtime with the charging case, according to LG.

SCALE Nanotech, an advanced R&D company based in Estonia, has announced the launch of its spinout Dragon Elements in Spain, aiming to enter into the XR and wearable electronics sector. Dragon Elements is set to commercialize LATIDO® capsules, a graphene-based technology designed to "redefine human interaction with hardware by eliminating the need for traditional audio and video components", as per the Company.

LATIDO® aims to mark a "radical shift in audiovisual hardware". Unlike conventional technology that requires separate components for sound and vision, LATIDO® harnesses millions of graphene membranes to seamlessly control both light and sound within a single monolithic device, removing the need for separate screens or speakers.

The new product will be a mid-range offering on Philips' product list, and the wireless, over-ear device will come with adaptive Adaptive Noise Cancellation (ANC). Inside, there are graphene-coated 40mm drivers that allow for high-resolution playback and Spatial Audio functionality.

LG Electronics (LG) has unveiled its new “xboom by will.i.am” audio product line of Bluetooth speakers and earbuds at CES 2025, created in partnership with musician and tech entrepreneur, will.i.am. 

The xboom Buds employ lightweight graphene drivers, which are key to delivering pure, well-balanced sound with rich bass. Graphene is said to improve durability while supporting LG’s Active Noise Canceling technology, providing a more immersive listening experience. Featuring LE Audio Auracast, the Buds enable users to listen to open audio streams in public and permit multiple device connections so that several users can simultaneously enjoy the same audio. Designed for comfort and stability, the ergonomic ear tips adapt to various ear shapes, while the unique ear hook design provides a snug and stable fit on the go. It offers up to 30 hours of listening time with the support of its charging case, as well as IPX4 water resistance that protects against splashing water.

Alienware debuted its Pro Mouse and Keyboard in January at CES 2024, and now the company is introducing the Pro Headset as part of the series. 

The headphones incorporate various technologies, including 50mm drivers that are coated with graphene to reduce distortion commonly found at higher frequencies.
