- in the desert...
While not exactly measuring, I do have a good eye dealing with precisely built things that get launched into orbit for the past few decades. Used my finger since have better feel for the driver and not poking into it. Basically the difference for the rear of the ear area is STAX L300 with L700 pads is between 1-2mm (closer to 2mm) deeper than the RR1. The RR1 is actually deeper (~1mm) in the front since the STAX is wedge shaped and shallowest at the front.
