ear buds with Cardo

Hey fam,

I recently ordered a pair of basic motorcycle riding earbuds from Amazon and use a Cardo Packtalk Edge in my helmet.

The earbuds have passive noise reduction rated up to 26 dB, but since using them, the music from my Cardo sounds much quieter than before.

Has anyone else experienced this issue? If so, did you find a way to improve the volume without compromising hearing protection?

Thanks!
