Cardo Scala Rider G4 / G9 / G9X Audio Kit 4.4 5 18 18
Very usefull Excelent for a second Helmet, Enought accesories for almost all types of helmets... I recommend February 23, 2015
Excelente base para Intercomunicador. Compre solamente la base para evitar el cambiar la base de un casco a otro. En mi opinión, el Intercomunicador Scala Rider G9 es un excelente equipo para comunicarse de piloto a piloto, lo he usado a mas de 140kms/hora a una distancia de 300mts con el otro piloto y la calidad de audio es muy alta. Debo decir que antes use otras dos marcas y ninguna me gusto tanto como el Scala Rider. February 9, 2015
Only product with all of the features I wanted I have been using a Cardo Scala Rider G9x for about six months. I like it because it not only offers blue tooth connection with my phone and GPS, but it also has a built in FM radio. I commute on my bike, and I like being able to listen to the radio. On longer rides, I'll listen to music stored on my phone or GPS. I have not used the intercom feature. I purchased this Audio Kit because my helmet was stolen! Fortunately, I had removed the electronic guts of the system and taken it inside to charge. Small consolation - I still had to buy a new helmet and the Audio Kit, but I did not need to buy an entire Scala system. January 5, 2015
With this audio kit i performe my G9 With this audio kit and the update for the G9 you almost have a G9x December 22, 2014
G9x Audio Kit for my "other" helmet I have a G9x and love the ability to use an in ear headphone. It helps block out extraneous sounds. Music, directions, communications are loud and crisp. Not muffled with the (in my opinion) cheap speakers that come with the unit. This unit can "replace" the clamp on system that came with the G9 to make the unit compatible with a plug in ear phone speaker. Give it a try... November 4, 2014
Finally a built in ear monitor plug! Moved to Scala from Autocom. Biggest challenge was using molded in-ear monitors for both surrounding sound attenuation and not having to blast the scala. Plug is convenient and love the flexibility of either helmet with speakers or simply unplugging the speakers and plugging in my Ear-Inc monitors for great sound at any speed, plus noise protection. Only problem on a previous buy (I have 3) is one plug seems to be getting loose on that one October 13, 2014
Great unit, the clear glue plate however is ungluing The unit itself is fantastic. If you can clam mount it i highly recommend that route. I couldn't on Shoei rf1200 so had to resort to larger clear pill off and glue plates. All was good but now afyer 3 weeks it's starting to peel off. October 6, 2014
Great solution to my problem, but wish I could have bought parts. When the earphones started going out on one of the communicators I had, I inspected the unit and found that one of the contacts from the radio to the audio unit was broken, so I was trying to find out if Cardio sold parts I could just replace. It turns out that they don't ... bummer. I was initially very irritated that I couldn't just buy one small part to fix my $500 unit. I had to purchase the entire audio kit for $60 with new microphone and speakers. It turns out that the new audio kit is better because you can plug in your own earbuds which is perfect because you don't have to battle with wind noise in that case. Honestly, they should have made the unit come standard that way, and maybe they will in the future. I do, however, wish that they would make small parts available to consumers so that we can repair things on our own. September 8, 2014

John C: This is a good com system. One reason that I like it is that it has an FM radio. Limited reception out of town, but I like to listen to NPR on my way to work.

Thomas S: Yes it should be. The old mounts for the g4 and g9 are interchangeable. My wife has the g4 and I use the g9. I know I have used both on the old mount. I will try the g4 on this mount in about a week when I get home. May 3, 2014

Actually I bought it after I wrote to Cardo to make sure it would be compatible. They assured me it was so that's why I got it and it works just fine.
May 4, 2014
Andrew R: Yes- it will work with the g4. I've got both a g4 and a g9 and have used both. Great piece of kit and works better than the various mods I've done to my Scalas over the years. May 2, 2014

A shopper asked: I have ordered Fit-Ear buds and would like to know audio kit will work with them? It will save me from having to send my original audio kit off to be adapted! Aug 3, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Air France Crew A: Not sure of what you're looking for and what you ordered but the speakers included in this kit work just fine for the use and they stay in the helmet so you don't have to go through the hassle of putting earbuds in and out every time you put on and take off your helmet. Aug 16, 2014
Michael L: This new G9x-compatible kit allows you to unplug the Cardo-supplied helmet speakers and plug any set of ear buds, headsets, or speakers that you want into the Cardo mount, just as long as it has a standard 1/8" mini-plug. Aug 5, 2014
