I have just pulled the trigger on UP4 2022 .. and I am afraid, though it's not really expansive, I will be disappointed once more, after :
2 x Qudelix 5K both with anorexic battery playing time (5 hours in balanced mode)
3 x iFi go Blu in 18 months ... and all dead due to probably some incompatibility with some USB-C chargers I use => it seems there is almost no power protection in this dongle to avoid over charging.
1 x FIIO BTR7 impressive sound quality as a BT dongle ... but really heavy, with a rather poor battery playing time (6 hours in Balanced mode 7.5 hours in Single ended mode)
1 x Shanling M0 .. the battery is now dead and became so thick that it opened the device in two parts in less than one year. Probably, due to the fact I used it mostly at office as an USB-C DAC on my workstation. I couldn't really try it as a BT LDAC receiver as the volume knob was too erratic to be used and no hardware button for changing tracks.

... Basically, I just want to hang the BT receiver on my sleeping T-shirt with a Beyerdynamic Xelento or a Sennheiser IE 800 plugged in, and I just want to play music for more than 9/10 hours which is the average time in the evening for reading some books and then sleeping in my bed an all night.

It's the last BT receiver I will buy for such purpose... and I just hope this time I will get a good sound quality, long playing time and long item life (2 to 3 years or more).

It's just 3 days I am using the Shanling UP4 every night :

1) It's smaller and lighter than expected (far less than FIIO BTR7).

2) Sound quality with my IEMs seems to be on par with iFi Go Blu and BTR7 ...

3) Battery playing time seems to be far better than BTR7 or Qudelix 5K and probbaly on par with iFi Go blu..
Unfortunately the battery indicateur under android seems to be rather unreliable .. it's going down rather fast to 40% left (within 5 hours) .. but then it stays a very long time at 40% .. even after 10 hours playing in singled end mode with some Beyerdynamic IEM (Xelento and Beat BYRD) ..
I will have to let the music play till the battery is totally drained to know if the battery playing time is 12h or more... then I will try in Balanced mode with the Xelento.

4) It seems to be totally hiss free with the Xelento (iFi Go Blu has a tiny permanent background amp hiss with the Xelento).

5) Unfortunately, the battery charging procedure is limited to 1A USB-C charger, which is really annoying in 2022 as most of the chargers can assume to provide the correct voltage and power to any USB-C items. I killed 3 ifi Go Blu with probably using some wrong chargers.

I will continue to use this tiny BT receiver....till it's working properly.

Just received the UP4 2022 today, is there a way to connect to an iPhone with an OTG cable and which one would be recommended please.

Is there a website for firmware updates?

Is there a website for firmware updates?

I think at least by OTA ? .. with Eddict Player APP.. my sample is with 1.3.5..

There have been no public firmware updates for UP4 22.

I got my UP4(22) today. The booklet says that there should be a choice of four filters, why does the Eddict app only offer two?

Also the highest band you can adjust on the EQ is 500Hz, is it supposed to be like that?

Original UP4 had 4 filters, UP4 (22) has only 2, this is due to different DAC chip being used.

But the EQ is clearly wrong though isn't it? I've played around with it, and it's effects obviously are not restricted to the bass. Perhaps you could pass that on to Shanling's app developer, so that it can be fixed in an update?

I'm not sure what you mean? The EQ interface goes higher than 500 kHz, you should be able to swipe left/right on the screen to move through it.

The EQ on the player can be swept left and right, but I don't use the player, I use streaming apps. The EQ on the Bluetooth device page has only 5 bands, the graphics display these 5 bands with the frequency values of the bottom five bands of the 10 band player EQ, which are obviously not right.

I can confirm it's the same for me on my OG UP4

 

[Shanling]

I'm sorry for any confusion, got confirmed from engineers that UP4 and UP4 22 is truly limited just to 5 band EQ. We got no explanation why is it stuck at 500hz as the highest, if it's decision of software team or just visual bug in the app.

I can buy the up4 2022 for about 50€ on Amazon warehouse, is a good device to use with sennheiser hd660s? I m considering the fiio brt5 too but the price is the double

Hello @Shanling I recently bought my UP4 2022 and I am struggling with the Digital Filter selection. I.e. I am unable to apply the Minimum phase (both fast and slow). I can only switch between the 2 Linear Phase filter. I tried while using my iPhone in bluetooth and my Mac both wired USB C and on Bluetooth. Searched on the user guide and internet and could not find how I can enable those 2 filters. Any advice please?
