💚PROS

Please refer to ZOOAUX

💔CONS

Amazon only release
May suffer from QC issues, if you are lucky you get a great copy, with $12 there has to be a compromise since this is not a bespoke handmade unit, it is an assembly line product, probably with near zero QC (just like tons of other ultra budget Dongles)

VERDICT

Xumee. After extensive listening sessions with all of my regular equipment, I drew conclusion that this Dongle unit actually shared the exact OEM Realtek ALC5686 DAC Chip internally as ZOOAUX 1st Gen, from the same factory, but finished and packaged under different brand for Amazon only release. It makes perfect sense as they are in similar form factor despite different exterior cosmetics. There’s no sonic differences that I observed between the two. Automatically Xumee ranks identical to ZOOAUX. It is also worth to mention that the advertising photo on Amazon site is inaccurate as it exhibited ALC4042 instead of ALC5686. I have verified this with TTGK Android app which allowed the user to inspect the hardware specifications of any Dongles attached to the phone.
