Recently published models on close binary evolution for massive stars (M greater than 5 solar mass) are compared to a set of detached and semidetached OB binaries. For the majority of the detached systems, we find good correspondence between theoretical and observed characteristics for stars with masses between 4.5 sola mass and 17 solar mass. We explore the origin of semidetached systems, and discuss anomalies between models and observed characteristics. An initial mass ratio of around 0.6 seems to be preffered for this group. Finally, we briefly examine a number of massive (marginal) contact systems. The latter systems all seem to evolve according to case A of mass transfer.
