How you all satisfied with he400 comfort? I mean 2+ hours of listening? For k550 I would say its perfect if its not happen that my left ear touching speaker frame, which I start noticing after about 2 hours. Reposition, and can go another hour or two. Sent from my SPH-L900 using Tapatalk

Thank you guys fot the quick answers. From what I hard from you all, seems thay he400 would be fit for what I like. Only things that I could complain about K550 that it can be sometimes sibilant with specific songs, but on the other side, clarity and detail are the best of all I heard (not much...

Is anyone here have both K550 and hifiman he400, or listened to both of them, to give me some insights? I want to add he400 for home listening, and I want to know how those two compares. Thanks! Sent from my SPH-L900 using Tapatalk

I have FiiO E10 and AUNE X1 MK2. SE-A1000 sounds good on E10, but bass sounds tighter on aune, from very start. Not more of it, just tighter and better defined. Maybe its good thing to cut cable short on pioneer (power hole) which might make difference. Cheers! Sent from my SPH-L900 using Tapatalk

What you like more on 840 over k550? Having k550 and liking them, woulbe nice if there is something even better for decent money Sent from my SPH-L900 using Tapatalk

Hey guys, can we find what is assumed as big head for K550, and good seal? I am 6'5", I assume that i have big head, my K550's are on 4 on both sides, I think that I have quite good seal, although pressing cups still makes bass ritcher. Also, on a loudest, person very close to me (1-2 feets)...

CASEBUDi XL is what I have for my K550, and its perfect fit. Sent from my SPH-L900 using Tapatalk

What are the nozzle size for mh1c and any suggestion for tips? Ones which come with them, even large ones are bit too small for my ear canals

I swear that this one benefits from burn-in!   A lot of people just left new headphones with white or pink noise looping on them for 20-50 hours, then they start to listen to them.   I did different, I started listening to them from very start, as I am truck driver, I have plenty of time for...

I just got them. On first listening, they sound really bad.. Veiled whole range, muddy bass, way too flat highs.. Hope Burn-in for these is real thing.

I am listening to phones 4-5 hours last few days, since i got them, and whole time there is strong odor of 'new electronics turned on for the first time' if you know what I mean?   Proof they really do 'burn-in' lol   Aside of that joke, is anyone experienced the same?

I think that Aune X1 is limited to 16/96, and upgrade to it, Aune X1 MK2 have all new DAC, can go 24/192 through USB, and is price marked around $200

  Good thought. I will try :) I have to say that I noticed that I am getting best fit with headband a bit more forward on head, but I guessed that was normal, as it is the same with Senn HD428 I have. Thanks :)

  I think I got quite a good seal, pressing speakers with hands to get better seal do not change sound quality, so I guess that is it. I am not really good with that, but I assume frequencies that are excessive are over 10K, probably even more, as 320Kbps MP3's sounds less sibilant that FLAC's...
