Updates to the vibration drivers in the headphones should deliver improved sound quality, and the comfort and call clarity have also been upgraded. AI noise reduction is used to isolate your voice during calls, and you can choose between sound modes in the partner Audio-Technica Connect app.

The headphones are more comfortable to wear and offer longer battery life than bone conduction technology.

Cartilage conduction turns your ears themselves into speakers, letting you hear music and calls all while keeping your ear canals free and open. Not only is this more hygienic than your average pair of workout headphones, it also leaves you free to stay in tune to your surroundings, keeping those runs and bike rides safer.

The brand has announced the ATH-CC500BT2 pair which, unlike many conventional headphones, provide stereo audio without blocking the ear canal. The open-ear design works by vibrating each ear's cartilage, allowing for sound to be heard without the need for bud insertion or over-ear immersion.

The ATH-CC500BT2 use cartilage conduction technology to transmit "high-quality" audio without the intrusion of in-ear buds.

These ATH-CC500BT2 headphones deliver audio by conducting sound through cartilage, leaving the ear canal uncovered so the wearer can still hear other sounds around them.
