faq

Can this communication set also connect with that of another brand?

Many modern communication systems utilize a universal Bluetooth protocol, allowing them to connect with other brands. However, it's important to note that interoperability is often limited to a single unit from another brand. Keep this in mind when considering cross-brand compatibility.

Does this communication system fit in my helmet?

We offer universal and brand-specific communication systems for motorcyclists. Universal systems fit a variety of helmets, while brand-specific systems integrate seamlessly with specific helmets. Check the "Additional Information" tab on each product for compatibility details.

What's in the box?

All necessary components for installation are included in the box with every communication system. Think of clips, adhesive strips, Velcro and other things. With a Duo set everything is double in the box.

What is the added value of an expensive system over a cheaper one?

In essence, a communication kit provides the ability to communicate with another device, be it your navigation, your mobile or another rider. The price of these communication kits lies, among other things, in the design, the build quality, but most importantly in the connection possibilities. So if you only want to listen to music, you definitely do not need to take the top model that allows you to communicate with up to 15 people.
