The first step was the acquisition of a Sony PHA-1 in order to enjoy the capacity and UI of my trusty iPod Classic, albeit with vastly improved SQ. At the moment, I am either using it with full-size cans or with HD25s. I listen exclusively to classical and jazz. Whilst the HD25s aren't bad (they are especially good at blocking out aircraft noise, and are comfortable with glasses), I do feel that they are lacking in transparency when compared to, say, HD600s, Grados or the DT-48. I dislike wearing IEMs (uncomfortable).
Here in China, DT-1350s (facelift, coiled cable) are available for about RMB 1,400 (USD 225). I have read that they are highly transparent but lack bass and dynamics. Is this the case? Does their transparency approach that of the DT-48e? I have also read that they are extremely uncomfortable when worn with glasses. If this is the case, that will rule them out. If I make this purchase, they will need to replace the HD25 as my in-flight can of choice...
I have also noticed that there seem to be an enormous number of DT-1350s on sale secondhand. Does this mean that owners are having difficulty getting the best from them?
Ultimately, will they do everything the HD25s do, only with greater transparency and resolution? Will they be good enough to render it unnecessary to take fullsize cans on longer trips? If so, there will be a pair of HD25s (mint condition with Oyaide cable) for sale soon!
Finally is there any SQ difference between the straight cable and coiled cable versions?
