I've never heard them but here are some FR comparisons:

Elear w/ stock pads by Oratory (orange) and Crin (green) - pretty much the same except Oratory using a regular coupler and more smoothing (Crin uses the hi-res coupler) so you see a bit more detail and peakiness in the Crin's measurement.

Elear w/ clear pads vs elex pads by Resolve (clear pads - purple) and Crin (elex pads - red) - more or less the same, both using the same measurement setup but different units.

Elex by Oratory (orange) and Resolve (brown) - the same low-end and air but strangely, Oratory's measurement shows peakiness in the lower treble and smooth mid-treble while Resolve's on the opposite is smooth in the lower treble and peaky in the mid-treble.

Here is the gross average of Elex (green) vs the gross average of Elear w/ clear/elex pads (blue) - except for those weird inconsistencies in the lower/mid-treble, they seem about the same.

Here are Elear w/ stock pads vs elex/clear pads. Should have a positive impact on the treble evenness but adds a bit of midrange honk.
