Never had any issues with hissing with my E17 using my Sennheiser CX 500 IEMs or my HD 555's and HD 280 Pros.

I just got a set of these as well from a member on here slightly used and I have to say they were totally worth it especially since they only cost me $55. My other set of cans are the Sennheiser HD 555's which weren't cutting it at work being completely open headphones. I needed something to...

Quote: Depends on what you're coming from? Are you using any type of DAC or amp right now? If you'd like to use the E17 just for the DAC feature you'll need to get the FiiO L7 which plugs into the dock port and has a micro-USB port and line out on the other side.

Hey all,   Just picked up some HD 280 Pros from another member and I'm really enjoying these for my set of closed cans. Only issue I have with them is they get somewhat uncomfortable after a couple hours. They come with pleather pads and I've grown accustomed to the velour pads on my HD...

I've just recently become the owner of a McIntosh MAC 4100 receiver that I inherited from my father along with a couple McIntosh XR14 loudspeakers. At this point I don't have room for the speakers in my apartment but I have to say I have been thoroughly been enjoying using the headphone output...

Quote: Perhaps it was certain shipments of the E17 that were affected. I bought mine from SonicElectronix.

Just got mine today as well. Love this thing! Had an issue with the clicking sound at first but I've worked around that and I knew about it before I bought it. All in all a great little DAC/amp, although my little pouch also smelled like gasoline as others have mentioned. Yuck.

I have to say my Sennheiser HD 555's are crazy comfy after breaking them in. At first they had a little bit too much clamping force but a few days after I got them they started breaking in and now I can wear them all day long at work for 8 hours and not have any discomfort.

I see the FiiO E7 is supported but what about the E17? I'd assume it would work but I'm not sure. I'm seriously considering switching from my iPhone to the Galaxy S3 (or S4) due to the ability of being able to use USB DACs.   EDIT: Nevermind. I found my answer. :(
