Does this ship from the US?

Can this be connected to my PC via USB for both data and 5v power supply?

Can this power IEM's without issue?
Not sure why the other person said no, this runs off a single type C to my PC. Runs my HD6XX fine, and why I got it a while back since those weren't getting enough from the onboard audio, so I presume it will drive most stuff fine.

I've had mine for almost a year, paired with Beyerdynamic DT 900 Pro X headphones with no issues. One thing I did was in bios I enabled the USB power always on. If you don't do this you will need to turn on its power everytime you turn on your PC, which is a long press of the volume knob.

Curious why it says "ships from Brazil". I just don't want to wait weeks for this. Estimate arrival according to the website is March 13-21.
Well, you're also circumventing some tariff nonsense this way..

Only if you have some hard-to-drive cans.

Does anyone know what DAC chip this uses? It doesn't seem to be mentioned in the Aliexpress listing.

The "no" was responding to the "ship from US" question.

What makes this a gaming DAC? Is it just marketing or is there anything in here that's specific to gaming?

It has a mic input. Most DACs don't.

I bought this a couple of years ago for $56 directly from Fosi. And in my situation it did not provide any benefit in sound. I use 2 PCs. One is the Surface 7+ Pro and the other one is based on the Gigabyte Z370 HD3P. The headphones I used were KZ-ZS10 PRO X and the Shockingly overpriced Sennheiser IE 80. Neither sounded better through this than from the headphone jack on each PC. Sennheiser sounded underwhelming in both and the KZ sounded equally good on both.
I did notice something though. There are 3 ways to connect this to your computer. USB, S/PDIF and Optical. The sound quality gets progressively better. Meaning USB has the least detail, S/PDIF is next and Optical provides the best sound quality.
Hopefully this is just the case in my situation and it will work out better for others. Mine has been sitting in its box for 2 years now collecting dust. Frown

Grabbed one, the RDC7C promo code was still active ($53.63 - $7). They seemed to still have a few units in stock.
