(Chi-fi IEM Review) BQEYZ Autumn: High resolution and well-balanced sound. Mild high frequency range, suitable for those who are concerned about stinging; low frequency range can be adjusted with three different tuning filters.

The fit is quite good, but the feel is a bit stiff due to the metal housing.

Sound quality description

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


The BQEYZ Autumn has a mild U-shaped sound that is neutral in nature. It's not for audiophiles who want to hear the original sound, but for those who prefer a warmer sound, it's a good choice. Compared to Summer, which was a little too harsh for some people, Autumn is much milder.


Please see here for detailed reviews on sound quality.


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


The BQEYZ Autumn is one of the top models in its price range in terms of audio specs, or rather, it is a relatively good model in all price ranges, but it lacks impact. The build quality is amazing, but the sound quality is a bit lacking compared to its sibling, the BQEYZ Summer, in terms of perfection and cost performance.


There are some shortcomings in the high frequency range, but it's also a little disappointing that the tuning filter basically only affects the low frequency range, so it can't improve that weakness.


In any case, considering the fact that there is an overly powerful competitor, the Moondrop KATO, the overall performance of the Autumn is not bad, but I would recommend it as the second best model in its price range. In other words, it would be better to try KATO first. Other competitors include the DUNU FALCON PRO.

General comment

When I think of BQEYZ, I can't help but think of the brand as being strong in piezo-multi hybrids, so the perfection of the single dynamic driver was unknown to me, and I personally doubted the quality of the BQEYZ Autumn. However, the well-designed magnetic tuning filter and good audio specs were more than worth the price, confirming that BQEYZ has high technology in this field as well. Nevertheless, it is undeniable that the Autumn tends to have a weaker presence in this price range, as there are state-of-the-art rivals in this price range, such as Moondrop and DUNU, which have even higher reputations for their technological prowess and have put all their efforts into sound quality and build quality.
