I've just listened to some chet Baker in mono and found that I had a central mono image rather than one either side Paul. these are the latest model, the M2 which incorporates an inline mic. I've also listened to some stereo music and the spread and balance seems ok.

At times, I hear two versions of the same voice, one panned left and the other panned right. Do yiu get this effect?

I'm not feeling too confident about their performance in environments with high levels of ambient noise. But, as I say, more later.
