Hidizs S9 Review (Headphone Adapter)

I'd probably call it fairly "neutral" and "resolving". In my case, yeah, I would say the JDS El DAC II beats it (even though they use the same DAC chip). But I think it makes a perfect addition to an iMac, especially because of the form factor. JDS has moved to my main system.
My S9 works flawlessly with my iPhone 12 mini (iOS 14.4.1) --- however, the problems with my MacBook Pro 13” (macOS Big Sur 11.2.3) persist, even when connecting via USB-C to USB-A MacDongle, then USB-A to USB-C cable (Belkin). The USB interface with macOS Big Sur appears to be broken.
Customer support from Hidizs is very good: They replied very quickly and I've now downloaded a Firmware updater. However, update is only possible from a Windows PC. Won't have access to one before Monday. Will let everyone know if the Firmware update fixes the problem.
Status now:
- Hardware not defective (works with iOS 14.4.1)
- Incompatible with macOS Big Sur 11.2.3: Stuttering/intermittent sound output
- Sound is great via iPhone: Not flat and lifeless for me at all. Full bodied, goes loud, no hiss if used with in-ear Sennheiser IE-800

Better: "What measures great isn't necessarily perceived as sounding great."

Yes that is better put. I own one it sounds simply amazing but I choose it because it does what it was measured to do not color the sound.

Actually it does if it measures great it will sound great for its intended purpose. If colored sound is what your after only look more towards tube amps.

I got a reply from customer support with a link to a firmware update tool and instructions. But my S9 is not recognised by the tool. 
Tried with several PCs and cables.

What was wrong with it that you wanted to update firmware? I did not even know you could update it I do not even have drivers since it does not need any for Windows 10.I got a reply from customer support with a link to a firmware update tool and instructions.

Wrote to the customer support and got a reply by a technician. Telling me the firmware might be the problem and said way to update it.

The best comment so far I've seen here in asr. Very direct and true.

Lets say: What measures great is more true to the music as intended.
Translated to food: a nice meal can taste boring if the cook used too little salt. Then its fine to add some salt yourself. But it would not be smart to add lots of salt to everything before having tried it. If the cook used enough or a little too much salt this would ruin it completely. And you'll never know how it was meant by the cook.
Speaking of headphone dongles this does not mean authority or bass headroom. But this is none of the measured parameters.
On an android tablet USB-C the S9 drives my DCA Aeon2 pretty nice already unbalanced. Looking forward to receive the balanced cable!
Was contacted by Hidizs Customer Support again. There seems to be another more complicated method of updating firmware. Hope that helps...

Can this kind of device be connected to a preamp?

I am using the S9 with an Imac and Audirvana and no issues. Sounds phenomenal and can even handle Dan Clark Aeon RT closed headphones.
