  The open clusters in the Kepler and CoRoT fields potentially provide tight
constraints for tests of stellar models and observational methods because they
allow a combination of complementary methods. We are in the process of identi-
fying and measuring parameters for detached eclipsing binaries (dEBs) in the
open clusters in the Kepler and CoRoT fields. We make use of measurements of
dEBs in the clusters to test the accuracy of asteroseismic scaling relations
for mass. We are able to provide strong indications that the asteroseismic
scaling relations over- estimate the stellar mass, but we are not yet able to
distinguish between different proposed corrections from the literature. We
argue how our ongoing measurements of more dEBs in more clusters, complemented
by dEBs in the field, should be able to break the degeneracy. We also briefly
describe how we can identify cluster stars that have evolved through
non-standard evolution by making use of ensemble asteroseismology.
