What's your experience with HM-801's game amp?  It is especially noticeable  with bass, the game amp is more transparent, the mids are also clearer.  Is the HM-801 Lineout quality the weak link?  or is the game amp just better?  The Concerto has higher current so there is more dynamism in...

Hi   I'm tired of the ultracrappy sound quality of my Samsung Galaxy S2 and the lacking of a USB LOD like the iPhone 4, so I'm currently in the search of a good portable rig and my three options are:   - iPod classic 160Gb plus a Fostex HP-P1 to be used as DAC and headphone amp. -...

RockBox For HiFiman HM601

hey all,   i haven't gotten my HM801 yet (well I did, but it was a buggy unit and only lasted 1 day) but one of the main concerns I have is the relatively low battery life.   this will probably only get worse as I intend to install the balanced amp module to use with some hardwired twag...

No need to carry those large power supplies around anymore ( If you are running the Rockbox firmware ). Simply plugging a USB cable that's already plugged into a powered USB port into the DATA EXC port ( Not USB DAC port  ) will charge the HM-801. There are 2 downsides to this. 1, the USB method...

Hi, I'm currently awaiting delivery of a pair of UM Miracles. I'm not a wealthy man (I shocked myself at stretching to so high a price for a pair of IEMs, and it's going to take me quite some time to pay off the credit card bill for them).   However, I'm curious  - yes, I appreciate that the...

  Anybody have the TRRS wiring spec for the 801? I had it a while back but I'll be damned if I can find it now.   Thanks!   se    

I just received my new Hifiman HM-801, and I can't get it going.  I can't get any sound out of it.  First of all, where is the play button?  Is it the pause button on top, next to the headphone jack?  In any case, when I try to play a track, pushing that button and any of the others on it, all...

I'm just getting my HM-801 working (WOW, sounds terrific!), but I am not sure what the amp board that came with it marked  "headphone amp board v.2.0 for Ganqi bay" is all about.  Is this an alternative amp?  What are its characteristics or purposes?  Thanks for your help!

Dear HM 801 community,   My HM-801 arrived over the weekend, with two amp cards, one installed and another in a little plastic bag.  There is nothing I can see that indicates what the two cards are.  I'm pasting pictures here -- can anyone identify them for me?  Are all 801s shipping with...

Does anyone know where to get replacement screws for the GanQui amp bay on the HM-801?  Mine stripped the first time I tried to open the bay...

I just bought a Hifiman HM801 and it came with 2 amp boards. The spare board is green with 4 transistors and 4 caps, it looks like the picture in the Hifiman manual. Inside is a blue board with 4 big chips and lots of little chips. Does anyone know what the difference between these boards is...

Ok so I have a new Hifiman 801. I can't even listen to the stinkin' thing because i can't get my music loaded. I have searched these forums and there are numerous threads from 5 years ago that don't seem to explain what I need to do and don't seem to pertain to current software, etc. Here is my...

  I Purchased a hm-801 a few months ago off Head Direct and until today only encountered minor freezes or glitches with it's firmware of which I'm sure they're aware of. Today after successfully transferring around 1GB of FLAC files to my 801's on board flash memory, it froze on the "Data...

Hello fellow HM-801 owners and lovers,   I am having real problems with cue sheets -- anyone have any solutions?  When I rip a CD to a single wav file with cue sheet (via EAC), and then convert it (and the cue sheet) to flac with Dbpoweramp, the HM 801 displays the cue sheet, but doesn't...

Hi, apologies if this has been answered before but after a lot of searching I am still not sure. I recently acquired a HM801 and I am really impressed with the sound quality but I am having problems putting music on the unit. I am using Media Monkey and DBPower Amp to convert all my ALAC files...

My HM-801 is not being charged at all but the battery icon continues to show the charging animation. I'm using firmware 0.21. Any way to fix this?

Hello:   What is the Line Out pin configuration of the HiFiMAN HM-801.  I need to construct a coaxial S/PDIF digital interconnect for the HM-801, presumably with a 4-pole 3.5mm plug.   Thanks,   Grayson

I followed the set of instructions that was posted here but when I get to the part that you select the hm-801 firmware with RK27Upgrade_Image it does not go anywhere and in the box I get several lines that say error. If anyone has a solution I would appreciate your help. Thanks

Hello everyone,   I have recently decided to go get myself the following setup:   HiFiMAN HM-801 -> HiFiMAN EF-6 -> HiFiMAN HE-6   The problem is that I'll be using the HM-801 as a dedicated source with my laptop, which doesn't have coaxial out. I am therefore forced to go USB, which...
