"Ultrasone knows how to make a good headphone"
 
And yet, for some reason, Ultrasone never takes the time to use that know-how to actually make something really spectacular (*cough* Edition 10 *cough*), instead relying on marketing buzzwords and their (B)S-Logic to get by.

I also had the opportunity to listen with the Edition M and it was a blast. Lightweight, comfortable and an amazing soundstage. Thank you Ultrasone for this headphone - it is a gift.

Too bas it use those very un-reliable MMCX plugs.  

How's the headband adjuster - cater for all sizes? I found the Sig Pros & E8 simply too big - even at hightest setting - needing a head cushion to make wearable. This wouldn't be practical for mobile use. Thanks

@Bopper29 The Edition M can be worn by children, that is how small the headband starts off at.  For me, I am a small guy and I had to go to about 3 notches up for it to fit me perfect. 

So, to answer your question, yes these cater for all sizes very well.

Great, sounds very encouraging on the size front. Thanks
