You can use the 3.5mm as a ground, but you need a special cable made.

What would this even look like? A 4.4mm male to 2.5mm male cable with an extra 3.5mm “dummy” attachment that acts purely as a ground? Do you know who would even make a cable like this?

Took a moment to find but knew I'd seen a cable like that before. A bit short, only in Japan, and seems to be out of stock but Amazon Japan appears to be taking back-orders:

EDIT: Not cheap but I have a couple of PW cables for my Oriolus amp and they are very well made. There's also a 4.4 to 4.4mm version (at bottom of 2nd link) which I assume is for use with an ungrounded 4.4 to grounded 4.4 connection.

Awesome, thanks for the help, and at least now I know what to look for! This should be a good stop-gap measure until I actually update my amp section to (hopefully) have balanced 4.4mm input.

Glad I could help.

Btw, does your HM1000 charge light turn green when fully charged?

Yes, it just takes a while if charging from a USB port on my PC. Have you (or anyone else who owns this thing) been able to update the firmware? I downloaded the file from Hifiman's site, formatted my micro SD card correctly, and took all the right steps, but mine is still running the firmware it shipped with, which is definitely a less current version.

Thought I replied to your question but guess I was too distracted sending my HM1000 back to Hifiman (waiting for a replacement; hopefully next one takes a full charge).

EDIT: I assume your card is formatted in exFAT (just for the update; otherwise FAT32 for regular use)

Version is misleading as it shows March 16 but the actual file inside the zip is from January (which the Remote app also confirms).

Yeah, I actually followed up with Hifiman and they confirmed what you posted. I'm sorry you got a lemon, I hope the next one works well for you!

this is my set info.
i dunno is it lastest firmware.

 

[muths66]

Anyone know what the fastest way to scan the media.I only able to use my mobile wireless scan it and took quite some time.

Mine had the same version. AFAIK, it's the latest; couldn't find anything newer on either Hifiman site.

I ended up using OTG which was about twice as fast as wireless. However, OTG starts out wireless (which took about 5min for me with a 128GB card and over 4K songs) then you connect otg cable when prompted and it's done 30sec later. IIRC, wireless took over 10min. Also tried "Manual" but gave up after waiting few minutes so no idea why it's there.

So, how does one actually load songs on the micro SD card on the HM1000? I’m really baffled, because you all seem to be having good luck. I have an iPhone and use a Windows 10 PC. I thought it was simply drag and drop when the HM1000 was connected by USB to my PC, but that’s clearly not the case. And Hifiman customer service confused me even more when I contacted them and they responded that the TF card was for firmware updates only.

You maybe can try use manual in hm1000 let it update the media after done you try connect to your pc.
1. Please click "MANUAL" then operate as the operation guide
2. Please wait for the update of the mediahub, when it is finish, connect your phone and HM1000 to your computer and copy the generated file "HIFIMAN.DAT" to the folder "hifiman/incoming"
i use my android phone to get it work by wireless.
i put DAT file inside my phone folder inaide hifiman. incoming and same DAT to sd card

Yeah, I copied the DAT file into iTunes on my PC since I'm using an iPhone with the app to control the HM1000. What I don't understand is where to load my music files on the HM1000, and how to get the app to recognize them.

you try my way. u need to install remote apk. then choose wireless on hifiman remote with bt on and pair it. it will auto scan ur sd card in hm1000.
