I'm not sure about this answer, because it depends on what you actually mean by listener, but here goes: I think men are better listeners. I think women like to talk too much, after all we do have somewhere in the region of 20.000 words to use every single day, that nr. is much, much lower when it comes to men. But then, we can argue if men are really listening and that is another subject altogether. Finally, if you mean really, really listening, well, then I think it's more or less the same, men and women alike.
