Sound quality description

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


The NF Audio NM2+ has a near-neutral sound signature in the midrange with a slight emphasis on the mids and highs, making it an excellent studio reference monitor. Both resolution and distortion are of a high standard, and the NM2+ meets the high specification requirements of monitors outside of frequency response. It is comparable to the best high-end models, and it would be rare to find a model that can compete with this earphone even in the upper price range. The only drawbacks are the lack of extension in both low and high frequencies, i.e., the compact imaging and sound field, and the lack of accurate localization.


Please see here for detailed reviews on sound quality.


Sound quality general comment
  • Original Sound Fidelity: A+
  • Recommendation: A+
  • Personal preference: B+


The NF Audio NM2+ is a very good monitor earphone. The resolution and THD specs are perfect, and the sound balance is well done. If I had reviewed them a little earlier, this time last year, I might have been more excited. I probably would have considered buying one.


Unfortunately, I must point out that there is currently a less expensive alternative, the TinHiFi T3 Plus, which offers better sound balance and specs. And with a little more money, you can get even better earphones called Moondrop KATO.

General comment

The NF Audio NM2+ is the first choice for users who are looking for a practical studio monitor for DTMs at a low price. It reproduces the sound of monitor speakers quite faithfully. The audio specs are excellent and far beyond the value of the price range, so you won't be disappointed with your purchase.
