  We show that in the bounded cohomology of non-abelian free groups the Massey
triple product is always trivial when the second factor is represented by the
coboundary of a decomposable quasi-morphism. We also show that in the bounded
cohomology of a negatively curved compact Riemannian manifold the Massey triple
product is always trivial when the second factor is represented by an exact
differential form.
