I used to have the 400s Personally I'd say 400i is an upgrade from 400s Bass is deeper + better high extension Better stock pads (400s' stock pads sux, lol), you could maybe say overall 400i has better build quality. 400s is neutral to warm(ish) - 400i is neutral to bright(ish), at least to...

My desktop setup says hi :) usually using 65 - 70db on the m9xx volume level btw

I ripped off the back cover on my brainwavz pads, fiiguring MA 900 drivers already have a fabric cover The thing is, i did this without using brainwavz pads WITH the back cover first, so i have no idea how MA 900 would sound with 2 fabric covers, one on the drivers + the backcover of the...

All brainwavz pads should have the same size I think All I did was basically just pulled them to fit into the slots on the MA 900

Brainwavz non angled pads on my MA 900 Just pull the pads over the earcups, it's so easily done Ears dont touch the inside of earcups anymore, and if any, sound changes (to my ears) are more pronounced upper mids / lower highs

  Hmm...maybe need to use the A5 bass boost on it ?   ===================   On a more serious note, a local Indonesian X5 iii owner used a needle (as in a tailoring needle) to open the sdcard slot instead of the provided pin   He pushed it too far in and probably hit the battery inside...

  Inside the "Music" folder

  I'm not sure about percentage in SQ improvement, kinda hard to quantify subjective measurements/preferences, i just know that my phone (galaxy s6 fwiw) couldn't drive 400i good enough for me.        I have the Fiio X5 iii and it can drive 400i (and my beyer dt770/80} good enough roughly...

I'm using 400i on a desktop setup with the m9xx (not gonna go portable with the 400i anyway, lol)   Using them around 65 - 73 ish on the volume of m9xx, depending on songs/moods, sounds great to my ear   Oh, I've also installed/using Peace GUI for Equalizer APO on this desktop setup, bumping...

Ah IC, didn't know that   Enjoy your new headphone !

  770/80 would prob need an amp if you use your phone as dap

  Haven't tried using UAPP & Foobar on my X5 iii   But both Hiby & Neutron support the dual microsd card   Neutron have Folder Play option. In my cards I usually do the folder organizing something like D:\Alt Rock\Artist A Album\   &    D:\Alt Rock\Artist B Album   etc etc. I can just go...

  Cheers

Probably a very stupid question, but how do I find user manual for Hiby ?   Have just downloaded it on my Fiio X5 iii   Right now I'm trying to make Hiby shuffle play a folder, and I have no ide how to do that   Folder structure is like this :   Artist A Collection\Album 1...

  I tried X5 iii with my DT 770/80 the other day (on low gain only btw, forgot you can switch to high gain, lol)   Maybe X5 can't drive the DT "perfectly", but good enough to my ears on low gain.   X5 iii is much more powerful than my previous AK120 for certain     So I don't think...
