BQEYZ Autumn Review


The BQEYZ Autumn is an in-ear monitor (IEM) using a single 13mm dynamic driver with swappable tuning filters. Unlike most IEMs with swappable tuning filters, which use screw-in nozzle filters, the Autumn uses magnetic cap filters which cover the Autumn’s bass ports. The Autumn was provided to me by BQEYZ in exchange for my evaluation. The Autumn retails for $200.


I have used the BQEYZ Autumn with the following sources:

  • Qudelix 5K
  • Hidizs S9


I have tested the BQEYZ Autumn with local FLAC and Spotify Premium. Visit my page to get an idea of what I listen to:

The BQEYZ Autumn comes in a rectangular orange box with a black slipcover. The slipcover features an outline illustration of the Autumn’s faceplate on the front and provides BQEYZ’s contact information and technical specifications for the Autumn on the back. The IEMs and other accessories are held in one foam mounting tray, and the included eartips are held in another. An instruction manual is tucked underneath the mounting sheets.

The Autumn includes six pairs of short, wide, and conical-shaped silicone eartips in two different color schemes. The light grey eartips appear to have a slightly shorter stem than the black eartips. The tuning filters are magnetically secured in a metal storage tray. A rod-shaped tool with oppositely charged magnetic ends is included for the installation and removal of the filters. The detachable 2-pin cable comes with a Velcro tie. A small cleaning brush is also included.

The semi-rigid zippered carry case is branded with the BQEYZ logo in light grey text on the top lid and has a mesh pocket for accessory storage. The carry case is large enough to fit the IEMs as well as the filter storage tray, the filter installation tool, and the cleaning brush in the storage pocket.


The BQEYZ Autumn has anodized metal shells with scalloped faceplates. The faceplate has a scale-shaped cross-section, and the shell body has a shallow U-shaped side profile. The slightly recessed 2-pin connectors sit in the seam between the faceplate and the shell body. On the inner shell body just below the seam between the body and the faceplate, “Autumn” and “BQEYZ” are printed in white on the left and right earpieces, respectively. “L” and “R” indicators are engraved into the shell itself rather than printed on, which is very neat. The circular bass port, into which the tuning filters insert, is located in the center of the inner face of the shell body. A recessed row of three smaller circular vents is offset towards the edge of the inner face of the shell body. The nozzles are metal and have strainer-style metal covers. The nozzles have a relatively wide diameter.

The included 2-pin cable uses four individual strands wrapped in a quad-braid below the Y-split and in a tightly wound double helix pattern on each side above it. The 2-pin connector housings, the Y-split, the chin-adjustment choker, and the 3.5mm jack housing all use polished dark grey metal hardware. “BQEYZ” is printed in white on the Y-split and jack hardware. The pins are slightly extruded to ensure a flush fit with the gently recessed connectors on the IEMs. Large “L” and “R” indicators are printed in white on the 2-pin connectors. The cable has some strain relief above the 3.5 mm jack with substantial strain relief above the 3.5mm jack and pre-formed earguides without memory wire.


The BQEYZ Autumn is intended to be worn cable up. The nozzles have an unexpectedly shallow insertion depth. The Autumn is fairly comfortable to wear but secureness of fit is somewhat poor. There is some driver flex with silicone eartips. Isolation is average.


Measurements of the BQEYZ Autumn can be found on my expanding database:

BQEYZ Autumn (Normal) — Squiglink by Bedrock Reviews


With the “Normal” filter, the BQEYZ Autumn has a U-shaped sound signature. The magnetic filters only affect the level of bass. The “Bass” filter increases the level of bass by around 2.5 dB in the sub-bass, whereas the “Treble” filter cuts the bass response by around 3.5 dB, resulting in a nearly linear bass tuning. I found that the “Normal” filter sounded the most balanced of the three.

The Autumn’s bass response is most elevated in the mid-bass, though sub-bass extension is good overall. The Autumn sacrifices some incisiveness and speed of bass articulation for raw impact. The bass is highly textured and has substantial note weight. There is some mid-bass bleed.

The Autumn’s midrange is natural-sounding overall and does not grossly overemphasize either the pinna gain or presence regions. The Autumn does opt for a discrete if restrained presence region peak. While I do not find it harsh or sibilant, the presence peak does skew the accurate rendition of distorted electric guitars, which sound too crunchy. It also slants the balance between male and female vocals towards female vocals. While male vocal intelligibility is passable, female vocals sound slightly forward of male vocals and are more vibrant and intelligible. Male vocals have limited body and warmth. Male vocal intelligibility and the overall midrange clarity are hampered by the mid-bass elevation. Timbre is excellent.

The Autumn opts for a very safe treble tuning, with some sparkle and limited air. Upper treble extension is poor. Treble transient delivery is natural-sounding, but overall detail retrieval is average. Instrument separation is good, and the soundstage is expansive in terms of both width and depth. Imaging is average.


The BQEYZ Autumn has a safe tuning and many of the advantages inherent to single dynamic driver designs, including timbre, coherency, note weight, and impact. However, its technical performance is average and certain aspects of its tuning, such as its mid-bass focused bass tuning and its limited upper treble extension, come with trade-offs I would rather not make.
