Pros: Best portable I've ever heard
Cons: Typical On-ear gripe. Hard to wear over a long time
So I got these used from another head-fi member for $220 shipping. EPIC WIN! I also won some HD25's from Razordog Deals back in June, so I get to compare the two!
I'm not into writing huge reviews since I don't consider myself to have "golden ears". I'll just say that the HD25's had horrible comfort issues and I hate the plastic build. The DT1350 are much more comfortable, but still have the typical over-ear issues. Pain after prolonged use.
The main thing I noticed was less of the treble sparkle on the DT1350's vs the HD25's. I like this because I hate piercing sparkle. Another thing I noticed is how the Dt1350 have more impact on the bass than the HD25's. I'd give the edge to the Hd25's for electronic, but for everything else, the DT1350 delivers.
That's my review. Short and sweet.
