Cardo Scala Rider G4 / G9 / G9X Audio Kit 4.5 5 23 23
Great product, one nit pick Really easy to install. I have the older version G4 and needed a new audio kit because the old one finally wore out. I got it second hand and it lasted me three years of good use before one of the speakers died. I love how the new version is not hard wired and you plug it in to the audio ports. Great product and I would definitely recommend. The only picky thing I have to say is I wish the speakers were as low profile as they used to be. They are more low profile than other brands I've tried but not as much as the older G4 ones. November 21, 2015
Truly enjoy the ability to send/receive phone calls and listen to music while m/c Product is overall very good and well worth the money. Revzilla is 1st rate with quick delivery of product at a competitive price. July 6, 2015
Great product Have the G9 and was frustrated with the inability to use my own headphones. Bought G9x audio kit as solution. Works great. Like the install options. Speakers could be better. June 30, 2015
The best sound of all of them. I have tried many Bluetooth headsets but by far this one is the best for sound and abilities, the Cardo Scala Rider G9x. April 6, 2015
Like the choice: earbuds or speakers Changing the base on my Neotech for the Scala G9 to this one having the option to use earbuds was a huge improvement. I only wish it originally came G9 powerset. I use Shure SE215-K Sound Isolating In Ear Stereo Earphones and also got the triple flange sleeves. They block the road noise and enable me to hear either music, intercom, Zumo or cell phone with lower volume and greater clarity. March 9, 2015
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

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

Air France Crew A: Absolutely! No problem at all!
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

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
