The Fosi DS2
The DS2 dongle comes with a cable and adapter and manual.

The DS2 is very similar in sound to the DS1, it is lighter inn build but still made of metal and has dual outputs.
It performed very well in both full-sized headphone and sensitive IEM.
The sound is a slight warm but very transparent quality with an open and airy signature.
Impressions: The DS2 sounds clean, with good details, transparency and natural tonality with a hint or warmth and musicality making it very pleasant. In A to B testing, it provided a louder and better sounding presentation than the stock DAC chip included. It has a fair amount of air and openness, and soundstage is accurate and above average in width and depth. headphones tested with the DS2 were the HiFiman HE x-4, the Fostex T20rp, Dekoni Blues, 1More Triple and Philips X2HR to name a few, IEM use were the Moondrop Kato, Sonic Memory SM2, NF NM2 plus, the Kinera Hodur and Moondrop Aria SE.

The DS2 is an exceptional value in my opinion, it offers a noticeable improvement at a good price to performance ratio.
