You can switch gain mode on the device itself without using an app.

So you're saying that functionality is not possible in Windows?

If that's true, and I'm not disputing that, ive never done it that way. I simply used the controller app one time to enable high gain and car mode and never used it again. I do use the UP2 with windows and it is completely plug and play but the gain setting was made using the app.

I began by asking a simple question: which is the best USB-C cable to use? I received the answer “we don’t test on MacBooks” (despite the fact the product is promoted as working on MacBooks). That’s not support. Yes, it potentially could be an Apple problem. If it’s an Apple problem it means the device is not plug-and-play for Apple devices and they should stop advertising it as such.

My main criticism is how incurious they are about it. I went looking for answers earlier in the thread and found examples of early users realising they were unable to charge from USB-C adapters. Shanling just shrugged their shoulders and said “use the supplied USB-A cable”. With the entire industry shifting towards USB-C ports and chargers don’t you think that attitude is a bit short-sighted? I just want to know why because then I can hopefully find a solution.

What is working:

• UP2 charges from Apple 5w charger (USB-A cable)
• UP2 charges from Ultimate Ears/Apple 12w charger (USB-A cable)
• UP2 charges from and works as DAC from Intel MacBook (USB-A cable)
• UP2 charges from and works as DAC from M1 MacBook (USB-A cable —> adapter —> USB-C port)

What is not working:

• UP2 unable to charge from USB-C chargers (USB-C cable)
• UP2 unable to charge/connect with M1 MacBook (USB-C cable)

I’m not an engineer but if I had to guess I’d say the UP2 is set to only expect a small amount of power and lacks the ability to negotiate a lower power delivery rate using USB-C. When it receives a USB-C cable input directly the high amount of power means it triggers some safety mechanism and won’t turn on. Does this sound about right, Shanling? Is this something you’re able to fix for future versions of your devices?

This is not the tone of your response earlier, it is a valuable thing to have a manufacturer here responding to support questions and I felt you were being unreasonable. I apologize for my vulgarity.

In my experience with apple and USB, things tend to be incompatible. Even if they work now they may not work later. Apple does weird things to make things "proprietary" and expects companies to follow their path instead of conforming to the industry standard. Sometimes it can be a good thing but in this case its a bad thing, and it usually hurts the Apple users which I find ironic because they keep buying more Apple stuff, its like Stockholm's syndrome.

Notice alot of Apple users pay $80 for an uncomfortable 1 button mouse?

Not always but generally, I would say if something isn't working correctly with Apple stuff, I would always point the finger at Apple first.

If the power trigger on the USB port is the cause, again thats an Apple problem to begin with. Not saying Shanling is completely innocent here but Apple should have thought of that while designing the macbook since thats an industry standard that they didn't feel like conforming to.

ASR's review of the UP4 is out. Amir said he could not get the unit to switch gain modes when used with windows as a DAC. Is this normal?

No idea what exactly is going there and what issue is Amir facing. You can normally change gain by double tapping the mode button, even when used with Windows.

You switch gain modes with the with iOS or Android Controller App. All settings are changed and controlled with the companion controller app.

You can do it in the app, you can also change gain and filters by the mode button.

Yes, UP2 and UP4 do not work with USB-C chargers, it was mentioned few times in this thread. Will hopefully be fixed for future devices of UP line.

I agree that it’s good to have a manufacturer here. As you identified my tone was pointed - this is because the manufacturer wasn’t providing support. I really don’t mean this to sound antagonistic but manufacturers aren’t just here out of the goodness of their heart - these forums are a great way to advertise products to audiophiles (which is exactly how I found this product).

I actually disagree with your point re: Apple and USB-C. Evidence online points to them being one of the most standards complaint regarding a pretty messy rollout of the new technology. For example, their iPhone fast charge uses spec-compliant USB PD while competitors such as Samsung, Qualcomm and OnePlus all use proprietary implementations. The only point where I can think of the Apple chargers being an issue is that some past models have limited PD profiles (e.g. the 29w charger with limited profiles which was supplanted by the 30w charger).

I’ve done some more testing on my Windows laptop which implies it’s not an Apple problem.

What is working:

• UP2 charges from Apple 30w USB-C with adapter (USB-A cable —> adapter —> USB-C port)
• UP2 charges from and works as DAC from Dell Lattitude laptop (USB-A cable)
• UP2 charges from and works as DAC from Dell Lattitude laptop (USB-A cable —> adapter —> USB-C port)

What is not working:

• UP2 unable to charge from Nintendo Switch or Apple 30w USB-C charger (USB-C cable)
• UP2 unable to charge/connect with Dell Lattitude (USB-C cable)

Seeing as both Dell and Apple laptops exhibit the same behaviour, and that zero USB-C chargers have worked, I would conclude that the Shanling UP2 has no real USB-C support and is not USB-C standards compliant.

If anyone has been able to make a direct USB-C to USB-C connection work I’d love to know how they did it.

Edit: I will add this just so I don’t come off as a negative Nancy - I do thoroughly enjoy the UP2. I purchased it on release and use it daily. The Bluetooth functionality is great for when I need to be portable but I love how revealing the sound is when used as a DAC. Being a two-in-one device, the UP2 has replaced my Audioengine D1 as a DAC.

DOuble tapping the mode button sometimes do not work for me, while using it in bluetooth. Although I use it in boost mode only, hence it does not matter to me.

But I am facing a problem. While I am using the UP4, in one hour, on an average, 2-3 times the signal will cut off and then resume again. Even while hte phone and the UP4 are close together with no interference between them. Please solve this @Shanling . This is really irritating.

This can be caused by random things, as we are dealing with Wireless in busy spectrum. Not something that can be just fixed without exactly knowing what could be causing it at your place.

I see...okay..

Could be a wireless issue but could be an Android issue or a player issue. If you stream high quality the phone (or remote server) can struggle or a music player may have a bug. It's possible to get bluetooth bug reports which could show up some issue. Worth looking into ...

Interesting. Will try. I am using UAPP. have to try other apps to see if it occurs. I have poweramp, foobar2000, and musicolet as well.

If you are having issues with battery on 3 month old unit, please contact your seller for warranty repair/replacement.

Is UP4 leathercase can be used as a clip on? I just clicked buy UP4 and searching for information here but not many about the leathercase..

There is strip of leather with a button. So it can be put on belts, straps, etc.

 

[AandutzDee]

@Shanling thank you for your response.. okay so i assume the leather case can't be used as a clip on then.. i bought up4 and the leathercase but it still on the way for deliveries, just curious when i see a post here with photo that the strap can be bent. When i googled back then, all the the strap photos seems straight... since i'm looking forward to use the clip on function much. Maybe will try some diy stuff

I ordered the UP4 along with a leather case, and they have been together from day one. Although the clip is not the most functional solution, the case is very protective and allows for a very easy operation of the wheel and function button.
The button clip is rather strong on the first months but tends to lose its strength as time goes by - which is natural. It is adequate to use on straps such as backpack straps, and (very) thin belts, but a normal clip would be welcomed in such a good quality leather case.
