Price dropped a few dollars. I'm not sure how easy it is to try and get an adjustment with AE or if it's even worth it for a few dollars, but wanted to give you a heads up.

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?

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.

No.
Yes.
Iems are still just 3.5mm headphones so yes.

That's simply how Ali Express works, I'm afraid ... long wait times in exchange for deep discounts vs Amazon which usually gets it to you within 2-4 business days.

I'm currently plugging my HD599 directly into my PC and I'm satisfied with the volume levels available; what benefits would this yield me? Just louder sound?

Cleaner sound, less noise and distortion, more headroom, less crosstalk etc

Most likely just more volume, but maybe cleaner amplification being separate from the motherboard. You have low ohm impedence headphones so it might make a minor difference in sound if at all. It's the high ohm impedence headphones that usually need headphone amps to sound the best.
The DAC might have more of an change. Possibly less noise compared to your motherboard dac/amp.

Oh my, I've had this DAC on my radar for quite some time. Good to see that it's on sale so I guess I'll pull the trigger.

I see the USB-C port at the back of this device. It's for connecting to PC/Laptop's USB-C port? Thanks.
