So I just got my 1350s yesterday. I have to say, I'm a bit disappointed. Isolation and soundstage are good, but the overall frequency response is a bit disappointing. Now they haven't broken in, so that might help, but I'm not really expecting major improvements. My primary purpose was to use it with portable devices. What surprised me was how different my various devices sound when used with these phones. The apple devices sound great, but my other device that I know have higher impedances just sound a bit more hallow. I thought that the higher impedance and higher sensitivity of the 1350s would make them perfect for portable devices. Maybe it's just my imagination, but my other cans that have half the impedance didn't exhibit as much variation as I see with the 1350s. My other choice was the B&W P5s. I had heard those in a store and saw a similar difference between my portable devices. Really confused if I should send these back and keep looking. Maybe I just need to get a portable headphone AMP.
Having the same initial experiences as me. Yes the DT1350's def need amping IMO!
These seriously benefit from a portable headphone amp when used with portable devices - even the FIIO e6 made a massive difference for me. Also, the positioning of the cups is key. Placing the cups slightly further back on your ear makes a marked improvement in the overall SQ.
I don't think burn in made a great deal of difference for me but amping and positioning definitely did! They have grown on me since i initially had them. Had to send mine off for repairs as the slider on the left side was loose and am missing them already. How things change :)
I also had a pair of P5's and since purchasing the Amperiors and DT1350's i have not missed them. The sound from the P5's are smooth for sure, but the detail, clarity and looseness of the bass was no good for me. The P5's are amazingly comfy though
Let me know how you get on.
