Today I picked up my iPod 5G 30GB which I had previously given to my brother(for about 3 years, so I'm not really sure of how it was used, or abused, in that matter) before going iPod Nano 6g -> Sansa Clip+. I installed Rockbox to the 5G right away, I didn't think of trying the OF first.
I'm using Denon AH-C560R IEMs (with the Comply T-400 that came with it).
The reason I want to use it is because right now, I use IEMs with the Rockboxed Clip+ which sounds better than the Nano 6G, but I also need the Nano to connect to the iPod interface of my car, which doesn't work that well with simple mass storage mode because it doesn't support playlist files, only through the iPod. The Classic 5G can dual-boot Apple's OF & Rockbox, and it also has more storage.
However, there are a few issues:
There is a hissing sound with the Denons. I tried some cheap earphones and the hiss is almost unnoticeable, but with the Denons it's higher than I find comfortable.
The low frequencies have really bad quality and the bass is distorted. I can feel the IEMs crackling slightly when there is bass and I'm worried they might be damaged.
Is there a way to fix these issues?
EDIT: I have fixed the distortion and bass by applying an EQ Precut of -10dB, however I still have no idea what to do about the hiss. Any help will be appreciated.
