@Claritas made these available to me for impressions and measurements. I think @Tyll Hertsens forwarded them. Thanks guys! These look like classic AKGs with their usual suspension band (which I think Mr Speaker's cans emulate). They are gray and black, which I like. The cans are elegant and lite. They offer ample room for ones ears and are relatively comfy, though the pads on these may be a little stiff. From AKG's page, these seem discontinued and are said to sport "varimotion" diaphragm: http://www.akglife.com/varimotion IMO the sound is a bit lean with some bright peaky tendencies. The overall balance is fine, but some songs get pretty annoying with these. Let's say I enjoyed Yellow River with these, but not California Dreaming. So some dudes at Headphonereviews give these high marks on mids detail and quality. I agree. Low marks on pretty much everything bass. I agree. High marks on treble. I disagree. Too annoying. Could recommend if one is into collecting cans. Cannot recommend in terms of audio quality.
