Hello there! Just thought I'd chime in. I lost my 1 month old DN1k recently and was looking to replace them with cheap iems before I get Noble 4 customs. So the astrotecs showed up on the radar. Having followed the thread, I went to audition and A/B both the ax30 n ax35 expecting to like the latter. The ax35 is very much like the Dunu. It had really good bass, digs as deep at the dn1k although with slightly lesser quantity. The mids were laid back, moreso than the Dunus I feel. There seemed to be something lacking there. The treble was very forward, bright and splashy. Very interesting earphones. But not my cup of tea. My worry is that they would be inconsistent, especially for a person who listens to a wide variety of songs. The ax30 was more balanced overall. Slightly rolled off treble but not very bad, nice smooth mids which are not recessed nor forward and tight, deep but less deep than the ax35 bass. Having come from the HA 4As and Phonak 112, it was a more comforting and familiar sound. These are brilliant for SGD 80. I wonder how the ax30 compares with the re-400 though. Anyone? They're around the same price range.
