I recently purchased the 45 mm upgrade speakers from Cardo Systems and offer this product review. In buying the larger JBL speakers I thought that if the stick speakers sounded so good, then these must be even better. In this video I compare the speakers outside the helmet and also on a ride, after installing in my Shoei helmet. The result was surprising.

To my ears the original speakers are noticeably louder.
I could barely hear the 45 mm speakers.

Yes, that was my impression too. When I first plugged them in outside the soundbox I expected to hear significantly bigger and fuller sound. When I heard what appeared to be the opposite, I decided that the soundbox was a must, because I could not trust the naked speaker to make my decision. When the soundbox result did not produce a bigger fuller sound, I still did not believe that I could make a final decision, so I still mounted it in the helmet for a last test, and that made me almost fully decide that it was a dud. It was when I put the original speakers back in the helmet that the decision was clear - these speakers were going back.

One thing I did not mention in the video was, the original speakers appeared to he more solid / heavier than the larger speakers. I figured that the drivers were not as robust (?) as on the originals and that probably was why the sound was not up to snuff.

Anyway hope this review helps someone who was thinking that it might be worth the 31% upgrade cost. NOT.

My simple test for speakers is to pick them up.
Good speakers weigh more than cheap speaker

Can you return the speakers after using them in your helmet on a ride?
