And beyerdynamic already has an IEM line, that looks almost exactly like these. Maybe at some point they'll chime in and respond to the post asking them how these are better.
I hope they're not exactly the same but the specs of the dtx101ie are the same as the dtx100 and the dtx71ie has the same specs as the dtx80. The dtx71ie housing looks like a new one. Actually skip that, it's exactly the same as the 80. I do like beyerdynamic iem's so i'd be rather more excited if there was one with a MSRP of $199 rather than rebadged earphones in a cheaper package, it remains to be seen.
Oh, and to answer an earlier question, existing beyer's iem's don't hiss much from my DAP's.
