My original mest cable, on the right side, is too loose of a fit. And the IEM has once or twice slipped off the cable and landed on the floor (carpet thankfully). I ended up buying the Effect Audio Ares S cable, and it's no longer a problem.

Thanks. I too was confused by what "standby" meant.

Did you try to see if it worked at 0% with Mango OS or another App in Android?

There was one instance (I can't remember if I was In Mango OS or Android) when I turned it off and then back on .... and Digital went from 87% to 89%! Did iBasso find a way to circumvent Conservation of Energy with this update???? :gs1000smile: Free energy for all!!! But seriously, I wonder...

I didn't reset, and Poweramp does report a "Audio engine failed to load" error. It's right below the > play button.

Now that I think about it for a bit, I did see some anomalies wrt power levels. About two days ago I turned it off in Android. The next day, when I powered up, it did read a drop in charge in Digital. It read 79%. When I rebooted it to Mango OS the Digital read 87% - which, iirc, is what it...

I never did a full reset either, and I'm not experiencing any battery drain. How many did a full reset and are experiencing the problem?

I charged both D & A to 100% last night and unplugged it from the charger. Shut down in Android with no APPs running. Just fired it up after 20 hours and A = 100% D = 98%. Edit: I did not shut down Wi-Fi before turning it off. Bluetooth was never on, since I never really use it. Edit 2...

For people having problems with the batteries draining when "off" - is that happening also in the Mango OS mode? Or just in Android OS mode?

Thanks to the whole iBasso team for the continued support of this wonderful product!

I don't like being "that guy" but Poweramp, Neutron and USB Audio Player PRO all worked for me after the update.

I've had the Zen Dac v2 for about a week now and am really loving it. I use it with my UM Mest Mk2 to watch/listen to videos and for gaming. I'm incredibly happy that there is no video/audio latency problem (unlike with my iBasso dx300 when used in USB DAC mode). Also, it sounds wonderful...

With all the supply chain problems, this is absolutely correct. Their continued engagement with the dx300 forum speaks volumes about the quality of this company. Everyone who is in construction or manufacturing is trying their best.

I notice that when I use the dX300 in DAC mode (USB from my computer) there is a latency issue with YouTube videos. This doesn't happen when I stream the videos by WiFi from YouTube. Any recommendations on how to correct this on the PC?

I had a little of what might be described as sibilance with some tips. It was really more of a "splashy-ness" in the upper treb's. Where I felt some of the uppers weren't decaying fast enough. But the ePro TW01's did away with that.
