What is Cardo Sync?
Cardo Sync is an open-ear, true wireless cycling communication systems offering effortless connectivity for riders to other riders and their phone for calls & music. It is powered by VOIP technology for Cellular Intercom communication, requiring a cellular network and the Cardo Connect app for full functionality.
What are the benefits of riding with Cardo Sync?
Cardo Sync makes staying connected with your group completely effortless. Say goodbye to shouting over the wind or constantly pulling over to regroup. Whether you're calling out hazards, navigating a new route, or just sharing a laugh along the way, Sync keeps the conversation smooth and clear. Plus, with premium sound quality, your favorite music and podcasts will sound incredible on every ride.
How does Cardo Sync differ from other earbuds?
Cardo Sync delivers the best audio experience on the market—without sacrificing your situational awareness. Engineered specifically for cycling, it attaches directly to your helmet instead of sitting in or over your ears, giving you unbeatable comfort and keeping you fully aware of your surroundings. Plus, it's lightweight, incredibly easy to use, and water resistant so you can ride with confidence in any weather.
What's the intercom range?
Cardo Sync is powered by our Cellular Intercom, run on VoIP technology. The range is limited only by data network coverage. So as long as you are within coverage, you can enjoy an unlimited range!
How long does the battery last?
You can count on Cardo Sync to keep you connected for up to 11 hours on a single charge—more than enough power for your longest rides. While exact battery life varies based on your usage and volume levels, it's designed to last all day long.
How heavy is the product?
At just 19 grams per side, Cardo Sync is so lightweight you’ll barely notice it's there—leaving you free to focus entirely on your ride.
What is Cellular Intercom powered by VoIP and how does it work?
Voice over Internet Protocol (VoIP) is a telecommunications technology that transmits audio calls over an IP network rather than traditional public switched telephone networks. It is the network technology that Sync is built on.
Do I need a phone to use Cardo Sync?
Yes. Cardo Sync uses Cellular Intercom technology and thus communication, music listening and phone calls are reliant on a cellular network and the Cardo Connect app for full functionality.
How does using the Cardo Connect app for Cellular Intercom calls affect my phone’s battery?
When using the Cardo Connect app for Cellular Intercom communication, battery consumption is similar to that of WhatsApp calls. Consumption may vary based on factors such as device model, battery health, screen usage, and network conditions.
Does the product fit all cycling helmets?
Yes, Cardo Sync is designed to fit the different types of straps used in most open face cycling helmets. The minimum strap length required is 7.5cm.
Will I be disconnected from the environment when using Cardo Sync?
No. Cardo Sync features an open-ear design that keeps your ears completely unblocked. This lets you enjoy your audio and communicate with your group while staying fully aware of surrounding traffic and your environment.
What is the data consumption when using the intercom function?
Cardo's Cellular intercom data consumption resembles any other voice over IP based apps (like WhatsApp and others).
Is the Cardo Connect App available for both iOS and Android? Is it free?
Yes, the Cardo Connect App is free of charge, does not require a subscription plan and is available at the Apple Store and Google Play.
Is my group call private?
Yes, only group participants can hear and talk to each other.
What are the Cardo Connect app OS requirements?
Android: Android 10 and above are supported. Older devices, for example Samsung Galaxy S7, which is limited to Android 8, are not compatible and cannot install the app.
iOS: iOS 16.0 or later is supported, as long as the device is compatible with the latest Cardo Connect app. Very old iPhone models or iOS versions are not supported.
What is the Wind Shield and why should I use it?
The Wind Shield is an optional accessory designed to reduce wind noise and improve microphone performance, helping maintain clear voice communication while riding.
Can I ride without the Wind Shield?
Yes. Cardo SYNC can be used with or without the Wind Shield, including in windy conditions. However, for optimal voice quality at higher riding speeds, we recommend using the Wind Shield.
What is Auto On/Off?
Auto On/Off is a feature that automatically powers the device on and off based on movement, helping provide a seamless riding experience while optimizing battery life.
Does Cardo SYNC turn on automatically?
Yes. When Auto On/Off is enabled, the device automatically wakes up when movement is detected.
What is the difference between Cardo Sync and Lazer VeloVox?
Cardo Sync comes with the new Auto On/Off systems for optimal battery consumption. In addition it includes the Wind Shield Attachment for high-speed cycling.
Does Cardo Sync have Sound by JBL?
No, but it features a suite of custom audio technologies designed explicitly for life on two wheels. You get a Cycling-Specific Equalizer for balanced sound, Wind Noise Reduction to keep calls clear, Ambient Noise Optimization to protect situational awareness, and Automatic Gain Control that auto-adjusts volume as your speed changes.
How many years of warranty do I get on the product?
You get two years warranty on your Cardo SYNC unit and one year warranty on the battery and accessories (according to state laws).
