Compact DAC.

Sounds really good. Works perfectly for both 3.5 and 4.4mm cables. No complaints.

Best DAC for the Price - Look No Further

I am thoroughly impressed by this DAC, after being disappointed by the HiBY FC4 DAC. For the price, there is not a better DAC that I can find. Of importance, this unit does not have an internal battery and uses a lot of power from the audio source device. Unfortunately, my Hidizs AP-80 Pro-X has a tiny battery (800mAH), so this unit does affect my play time. However, this is NOT the fault of the DS2. The DS2 provides great power and sound, as it is designed to do. My performance issues are based on the battery of my DAP. If you search online, you will see that benchmark testing places this DAC above several dozen more expensive units, based on scientific testing. I now trust this brand wholeheartedly.

Excellent DAC, Regardless of Price

Amazing how far DACs have come in the past few years, 4mm balanced and 3.5mm SEO connection options, incredible detail, and more than enough power for desktop and mobile use. Built like a tank. Recommended.

Works great

If you have decent headphones this works great. Mid tier and above headphones sound great for on the go power and clarity for the price. Very happy with this purchase

Hopeful, but Cynic
You can't receive calls with it.

One would think that a DAC for phones would allow you to take calls, but in the case of this DAC, one would be wrong. I'm returning it. The DS2 cannot be used as a normal phone jack would be, despite it being labeled as a portable DAC for phones. It cannot take microphone input, it is only for rendering music. It says so in the user manual, but nowhere on the web page.
