I have these. Both of our boxes say 10mm. The website says 12mm. I definitely hear 10mm bass. Also these sound like Blon bl-03 but a touch less sub bass and higher sensitivity. These handle higher volume without distortion.
@@VortexReviews1 TRN corrected the printing error on the box; it now states that the driver is 12mm instead of 10mm. TRN Orca is pretty impress for 10$
