My number one goal at the Los Angeles Head-fi meet today was to demo the HE-400i and make my decision on it.
Meets aren't a great environment for open headphone listening, but I had some solid time with them. Almost no one else knew the were there. They were factory fresh out of the box as well.
I had the HE-560 next to me for comparison.
I was all set to order a pair, but now it's almost no contest - HE-560 was clearly superior for me both sonically and comfort.
The sonic difference was expected, but I hadn't imagined it would be so significant for me. Based on the reviews, I thought the 400i would fit my preferences better. That couldn't be further from the truth.
More importantly, for me anyway, was the gap in comfort. The 560 faded away on my head. Aside from LFFs Paradox, I've never felt a more comfortable headphone; Not the Mad Dogs, or the Sony MA900, or HD598/5. All of which I own. The 400i felt heavier despite being a few grams lighter. The clamp was the most noticeable difference. The 560 falls effortlessly over the ear but the 400i felt snug in a way that didn't appeal to me. I rank comfort first and sound second because comfort is pivotal to my listening experience. Sadly, the 400i came up short for me. Note: I have a larger, funky-shaped head so YMMV.
Both headphones appeared to have the Focus pads. I tried to verify, but no one could.
Looks like my wallet is going to take a bigger hit than I expected. Time to save the difference for the 560.
