Have you actually seen the headband? On the pictures (worn by a man) they don't look wide at all.
I've been in many big cities in Germany recently (Düsseldorf, Köln, Berlin, Leipzig, Dresden, Dortmund) for business trip and I checked in every city if they have these yet (Saturn, Media Markt), but they all said they aren't available yet. I guess there's no early release like with the L1, which I got 4 months before official release. But I saw that some stores sell the L1 for 199 € so I wonder how they will price the M1 - hopefully 149 €!
