there is hissing in my unit when I use 4.4mm Balanced but on 3.5mm there is none
I tried to use it on my phone and there is no hissing but you need to nake the DAC in a steady position, any movement will cause the hissing to trigger

It would have been better not to have a 4.4mm out in the first place. Nothing is worse than a buzz, hiss, hum, or any kind of pitched noise. Back to using the apple dongle.
Many people report this problem but I don't understand if it is a defect in the various units or is related to a faulty USB cable. I don't have this problem perhaps because I use an L&P WP2 as the cable for all my dongles but if anything, try replacing the cable to understand if it is a defect in the unit or a defect in the cable (which it could also be). Even a USB computer cable can be fine for testing.
I have the same problem as well. When connecting a low impedance (16ohm) high sensitivity (126dB) IEM to the 4.4mm output, no hissing or dut dut (pop sound) when the dac is connected to either via phone usb c source or PC usb source. But, when the music started, before any instrumental/vocal is heard (the silence part of the track), hissing will be present. Funny thing is, during the start of the track, dut dut sound is heard, then after the track ended, another dut dut sound. Tested with 3.5mm and no such issue. Not sure is faulty unit or poorly design internal circuit for the 4.4 out.
Shanling need to stay with akm chips and house sound is a true winner...with sabre have same sound analitical with majority od dac amps from China....Topping to mention one....lean sound
A comment from a troll.
The UA4, like the FiiO KA17, has flawless musicality, but obviously preconceived ideas are very hard to forget, especially on Head Fi!

I found an easy way to check if hissing is present. When playing a track with an IEM connecting to the 4.4mm output, either High or Low again, reduce the volume to 1. For my unit, I can clearly hear hissing.
