It doesnt rattle AT ALL. Finally something a little more realistic. A phenomenal waste of time ????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Cette enceinte JBL est celle pour moi qui a le meilleur son, étant musicos, je fais super attention à ça! The outside of the charging port is scratched and ruined, but I saved a lot of money. Los audífonos cuentan con gomillas de distintos tamaños, para satisfacer a varios tipos de tamaños de oidos. The bass itself doesnt fall victim to distorting, but I find it too forward and wide, and a tad too much of the details in the mids and highs become lost in songs with heavy bass. I then found a quiet room an did the ear tests. However, since changing their manufacturing process, these earplugs have become worthless garbage.
