M17support Power Delivery as well up to PD 3.0 and here are the specs... I tested a PD charger and it works for charging but it doesn't activate Enhanced over ear mode

I just found that one of my Samsung 10000mha powerbank (Samsung EB-U3300XJEGEU) with a 5.5mm usb-c adapter has enough juice to be drained to be able to activate the enhanced over ear mode and keep battery of the M17.
Enhanced mode is really nice and worth with the DCA Stealth.

It's already more than 30 minutes, I am listening some DSD in enhanced mode and M17 is staying at 84% battery level (it seems it's draining between 9V to 11V at 1A), when I stop listening it's charging the M17
Another power bank seems to work like the samsung (BOOSTEXX 10000 mAh).

When I downloaded this morning UAPP I got a message that new version v 6.0.3.2 was installed.
Then, it told me when I launched UAPP that it was going to use the Internal DAC Hires that was detected when I don't use an external USB DAC.
Thank you, I have reinstalled and the pop up showed. With this update they have added support for the M11 but sadly, my M17 still resamples DSD to PCM. Hopefully they will update to support the M17 soon. Or maybe there some setting within UAPP that I need to activate if so, some help would be very much appreciated also, how can I Gert UAPP to update automatically? I had to reload my entire database and with over 500GB of music to scan, it was a bit of a pita.

PS: Intalling Screenshot touch from the google play store allows screen shots to be taken from the M17 (as I am doing)

I tried all to DSD and it is still resampling.
Maybe it was your M11?

Enhanced over-ear headphone mode only work with DC in.

Yes .. so I use an USB-C to a 5.5mmx2.1mm adapter. and I can access to the enhanced mode. With these two batteries I can do it.

Interesting, you have the full 12V/3A with that?

I looked on the top of the screen in the bar and it was indicated 2.8M .. I wil try again to confirm

No ... I put a usb-c volt meter between the power banks and the USB-C to 5.5x2.1 adapter and it is indicated between from 9V to 11V at 1A ... but enhanced headphone mode is activated.
I am still not in the time for me to analyze the real sound quality analysis between all of these power sources, but just look what is possible to do.

Does it make a difference though? From the spec sheets the power output at low impedance are the same with over-ear and enhanced over-ear mode.
But with the Stealth SQ is really changing when I switch between modes even on samsung battery .. I can't confirm if it's in a good way or not, I will try this week end.
My target are to move properly the Stealth and the HEDDphone one..

Where did you see this?
Comparison between over ear and enhanced is significant 12.4V single ended and 24.9V balanced vs 17.5V and 35.3V in enhanced mode...

I have the samsung power bank to keep the fold3 appalling battery from dying on me. Can you advice what USB-c - 5.5mm adapter you are using? Maybe a link to amazon.
There are several on offer ranging from £8 to a whooping £40 and with different power/voltage output and minimum powerbank output requirements for them to work. I have no idea which one to get. Thanx in advance

at 16Ω both are 1.5W.

They do sound a bit different when I plug/unplug the dc connector. In Enhanced Mode bass extension might be a bit better. Headphone mode vs Enhanced Mode, both balanced output at 32Ω load:

Enhanced mode rolls off at 10Hz, while in headphone mode at 20Hz.
