I did not want to spend the $$ for the Cardo system, just didnt see the value there. After looking through reviews of motorcycle com systems and prces, I settled on the EJEAS system due to features, ease of use and price. I can say that I am 100% pleased and satisfied with what I have, it actually performs better than expected. I have it installed on my helmet and my wife's helmet, and it works really well, with pretty good noise cancellation. Installation was easy (just removing pads inside the helmet & using supplied velcro stickers. Pairing is supper easy. Only thing I would recommend EJEAS would be to provide some sort of attachment for the mic for full face helmets. I just used a small piece of electric tape and done!
