W ireless headphones have come a long way, but Audio-Technica has taken a unique approach with the ATH-CC500BT2 Wireless Cartilage Conduction Headphones. Instead of traditional in-ear or bone conduction designs, these headphones use cartilage conduction technology to deliver high-quality sound while leaving your ear canals open. For tech enthusiasts, athletes, commuters, and office workers, this is an exciting development—an open-ear design that keeps you aware of your surroundings while providing immersive audio clarity. But how well does it work in real-world conditions?

First Impressions

The ATH-CC500BT2, immediately stands out as lightweight yet durable build. Crafted from a combination of titanium and silicone, the neckband-style design ensures both comfort and longevity. At just 32 grams, the headphones are impressively lightweight—perfect for extended listening sessions without discomfort. Unlike bulkier over-ear models or in-ear buds that can cause fatigue, these headphones gently rest on the ear cartilage, making them a non-intrusive alternative for all-day wear. The matte finish and minimalist design give them a clean, modern look, making them suitable for both casual and professional settings. Some might prefer more sporty colors like the Suunto model. With this product, Audio-Technica, is true to its value and general public expectations – Simple and effective.

Cartilage Conduction –  Is it really a new technology?

Traditional headphones use air conduction, sending sound waves through the ear canal. Bone conduction headphones: vibrate the bones of your skull to deliver sound directly to your inner ear. Cartilage conduction is a new technology first discovered in 2014, and sits in between these two technologies. Instead of using your ear canal or skull bones, these headphones use the auricular cartilage to transmit sound vibrations, and turning your ears into a stereo speaker.

The main advantages of this technology are:

• Extended Use – Cartilage conduction requires less pressure than bone conduction systems making it perfect for extended use.
• Comfort – Cartilage conduction vibrations are softer than bone conduction systems, making it less prone to to discomfort at high volume.
• Sound Quality – Cartilage conduction is associated to better sound quality and can deliver stereo sounds.

Performances

Sound quality

With an open-ear design, you’d expect some compromises in audio quality—but Audio-Technica has optimized the drivers to deliver well-balanced sound. The Acoustic Pure Sound Stabilizer minimizes distortion and enhances clarity even in noisy environments. Contrary to most of the open-ear design headphones, high frequencies are clear without sounding harsh, vocals and instruments sound natural and precise. Still the bass are present but not overpowering, similar to conduction bone open-ear designs.

Battery Life

The ATH-CC500BT2 features 20 hours of playback on a full charge, fast-charging (10 minutes of charge = 2 hours of playback) and a USB-C charging port for universal compatibility. It is a perfect option, even for heavy users,  long commutes, workdays, or workout sessions without the need to recharge.

Additional features

The pairing is quick, controls are intuitive. The audio latency is minimal, and the connection is stable, thanks to the integrated Bluetooth 5.2. The ATH-CC500BT2 is packed with must-have features that are sometimes missing on similar products. Audio Technica has done a great job in integrating:

• Multipoint Bluetooth Connectivity: Simultaneously connect to two devices, enabling smooth transitions between my laptop and my Phone
• Voice Assistant Support – Compatible with Siri and Google Assistant for hands-free controls.
• Water-Resistant (IPX4 Rating): Protected from rain and water splashes, making it suitable for outdoor activities or water-related housework.
• AI Noise Reduction (AIVC) : intelliGo’s AI technology extracts only the speaker’s voice during calls or online meetings, reducing environmental noise for seamless communication, and allowing up to 10 hours of continuous talk time.
• Connect app: Featuring Clear Voice Mode for enhanced dialogue, BGM Mode for relaxing background music, and Limit Sound Leakage Mode for public places. Customise sound quality with preset equalizers to match your taste and mood.
• Soundscape: Use the Connect app to access soothing nature sounds or masking noise for better focus, relaxation, and meditation, all designed to enhance your mental well-being.
• Voice guidance function: Stay informed with voice alerts for power, pairing, and low battery notifications, keeping you in control at all times.

A Runner’s Perspective

As someone who logs 30-40K a week, I’ve gone through my fair share of running headphones. Most earbuds either slip out the second I start sweating or block out so much ambient sound that I feel disconnected—and honestly, a little unsafe—when running through the city. The ATH-CC500BT2 completely changed that. On my usual 10K loop, I can actually hear my playlist and stay aware of traffic, cyclists, and other runners. The open-ear design meant I’m not constantly glancing over my shoulder or missing a friend’s greeting mid-run. Unlike bone conduction models I’ve tried, these didn’t cause that weird vibration discomfort after an hour of use. The secure fit meant no annoying mid-run adjustment and the lightweight frame makes me forget I even wear headphones. With the 20-hour battery life, a weekly charge is enough for daily training sessions, commute, and taking some call on the go.

Conclusion

After weeks of testing the ATH-CC500BT2, I can confidently say these are some of the best running headphones I’ve ever used. They strike the perfect balance between awareness, comfort, and audio quality, solving problems that have frustrated me for years. Whether I’m tackling my usual 10K loop or just heading out for a casual walk, they stay secure, sound great, and never make me feel cut off from the world around me. Audio-Technica has made a game-changer product for those looking for a solid sound quality, long battery life, and an ultra-lightweight build.

The ATH-CC500BT2 is a no-brainer for anyone who wants great audio without the usual trade-offs. Trust me—once you try them, you won’t want to go back. However, bass lovers and those seeking noise isolation may want to look elsewhere.
