(IEM Review) Shure AONIC 3: Only localization and resolution are good, but that's all. A rare lo-fi sound nowadays, created by a marked lack of extension and transparency.

The fit is not flattering, worse than Etymotic Research. If you have small ears, they will pop out of your ears.

Sound quality description

In this review, I use the standard eartips size L and drive it with the FiiO M15.


The Shure AONIC 3 has a warm-neutral sound. The sound tends to cluster in the midrange, with high resolution and good localization, so the midrange is clearly audible, but the texture is unnatural.


Please see here for detailed reviews on sound quality.


Sound quality general comment
  • Original Sound Fidelity: B
  • Recommendation: B-
  • Personal preference: D-


The AONIC 3 is the least expensive of the current AONIC series, but based on sound quality alone, it is probably the most decent of the 3, 4, and 5 in the current series. High resolution and localization accuracy make the AONIC 3 a somewhat practical monitor earphone.


However, they are riddled with the usual problems of SHURE earphones, including a high distortion rate, muddy and hard-to-hear low frequencies, a cagey sound with no discernible disconnect, and a complete lack of exhilaration. It is not a phone.


For some reason, Shure has a bad habit of not focusing on distortion rates and continues to produce distortion-prone audio equipment. The headphones have good sound balance and the distortion rate in the midrange is not so high that it becomes a problem, so much so that it is rather excellent, but the earphones have always been bad because the sound balance is poor and there is almost nothing good about them at all.


It was not so noticeable before because the surroundings were not good and it could be said that it was within the range of individuality, but if they are producing products like this by the standards of 2022, we can't even look at them.


If you bought KZ earphones these days with blinders on, you'd likely get better earbuds than these.

General comment

SHURE is known for great monitor headphones, but the earphone department is really not good. If you have the money to buy the SHURE AONIC 3, there is a good chance you would be better off buying the next earphones in the same price range with blinders on. Couldn't they have done something about the design?
