The Moondrop Starfield was already an incredible IEM for the price. With the Moondrop Aria, you get a much better cable and slightly better technical performance at a lower price. While I do not feel that the Aria offers technical improvements significant enough to warrant a purchase from existing Starfield owners, if you’re just getting into IEMs, you would be hard-pressed to do better than the Aria at the sub-$100 price point.
My full review, with measurements, additional images, and an in-depth comparison to the Moondrop Starfield, is available on my blog:
