These are my new favorite IEMs, better than the FH3 and those are for 130 dollars, that's all you can leave.

These are soooo damn close for being a 10, but that one flaw that I knocked down half a point that I’ll elaborate right this moment.

Build Quality

The tips that came with the IEMs aren't good. None of them isolate nor fit that great, I’d had to find the rubber clear/red ear tips that fits in my ears perfectly on the FH3s, but even then it doesn’t  match up the isolation and fit as the FH3, which is my ears fault not the product itself. The casing on the actual IEMs is phenomenal, I liked the black and gold aesthetic of the Aria, it looks as if I were carrying something fancy and elegant. The cable has a shoe string like material, at first I didn’t like it, but It didn’t really bother me that much, not the worst cable I’ve used on a IEM. 

Sound

This is where the praise begins. 

My god they sounded so good for the price. It’s even better than the FH3. These sound sparkly. Depending on what song, the vocals, especially female vocals sounded so satisfyingly sparkly and clear. The Aria has the sub-bass bump on the graph, and that bump is really worth it. It's not one of those enhanced bass were it sounded bloated, its more of satisfying very low bass that vibrate your house but instead your ears. However the mids are a tad weak, that’s the only minor complaint about the sound of these. Overall the highs and bass really makes the Aria shine.  The fact that these sounded soo good under 100 dollars is mind blown. These sounded as if they're over $200 dollars.

In conclusion: Moondrop really *drop* the ball with the Arias. These claimed to be my new favorites Earbuds.
