Abstract Let (c n) n∈Z be a double-sided sequence of complex numbers; if, for quasi-all (i.e. in the Baire sense) choices of signs (ε n) n∈Z , (ε n c n) n∈Z is a Fourier-Stieltjes sequence, then we prove that (c n) n∈Z ∈l 2 (Z); this extends a result of Littlewood and at the same time provides a very simple proof of this result.
