I have just received my ETHER. It is my first open headphone, coming from a background of IEMs, and it has greatly exceeded my expectations. I have demoed a number of headphones over the years but nothing has ever completely clicked with me. There always seems to be some distracting aspect to them.
ETHER just gets out of the way.
I think a lot of that has to do with how comfortable they are. Similar to my CIEMs, once they have warmed against your body they simply disappear. It is also due to the signature, which seems very balanced, cohesive and natural. They are articulate and revealing without becoming 'hyper-detailed', and imaging feels precise.
Simply put, they present music that I know and love in a very effortless, enjoyable and foot-tapping way.
If anything, there is a ssss to the treble that I am still getting accustomed too. I wouldn't say it's sibilance, it isn't necessarily unpleasant, just different. Perhaps it's 'air' that my IEMs haven't been able to reproduce.
Congratulations to Dan and all those involved at mrspeakers for creating such an accomplished and thoroughly enjoyable headphone.
PS: It seems I have overestimated my girth
If anyone who ordered ETHER but missed out on the preorder t-shirt would fit size L, I would be happy to send it to you (after you have posted your impressions here, of course...)
