The folks at BQEYZ are best known for their hybrid and multi-driver efforts. Their popular models such as the Summer or Spring had DD + BA + Piezo configuration. In fact, BQEYZ is one of the few manufacturers who still use Piezo drivers and has extensive know-how about this driver type.
The Autumn, being a single-dynamic offering, mark a shift in BQEYZ’s approach. Simplifying the driver count allows for easier tuning but also makes maintaining technicalities a challenge.
Do the BQEYZ Autumn pass the hurdle, or do they fall by the wayside? We’ll find out in the following.
The BQEYZ Autumn come with 6 pairs of eartips, a 4-core silver + copper mixed cable, and the proprietary tuning magnets along side a tool to remove the magnets. A carrying case is also included which gets the job done without being flashy.
General fit and finish are excellent here, with the BQEYZ Autumn having a polished aluminum shell. The shell is a two-piece design with the seam between the pieces barely noticed.
There are three vents on the inner-side of the IEMs. The nozzle is also metal. Lastly, BQEYZ has opted for 0.78mm 2-pin recessed connectors, which I personally prefer over flush or raised connectors.
Comfort and isolation
Comfort is very good but isolation is lacking due to the vents placed on the inner side of the earpiece.
BQEYZ went for a 13mm single dynamic driver here, with not much being told about the diaphragm material. Elle Zhou confirmed that they are using a 6 micro-meter ultra-thin PEN diaphragm.
The driver is housed in a dual-cavity structure which is becoming pretty standard lately.
BQYEZ Autumn Sound Analysis
Listening setup: BQEYZ Autumn with normal filter + stock cable + Radius Deep-Mount tips + Sony NW-A55
The BQEYZ Autumn have a slightly V-shaped tuning with emphasis around mid-bass and lower-treble. What makes them stand out is how relaxing the signature is, as the transients are rounded and leading edge of notes are softened out.
Bass here is mostly characterized by the mid-bass bloom that adds some extra decay to bass notes. Snare hits also get extra thickness and body as a result. This tuning works well for moderately paced tracks but leaves you wanting in fast metal tracks.
Sub-bass rumble is lacking, so sudden bass drops lack the physicality you expect. Macrodynamic punch is lacking as well, so the BQEYZ Autumn isn’t really suited for portraying the energy in tracks.
Mids are fairly well tuned. Lower mids are recessed but doesn’t sound drowned out. The recession gives a sensation of laid-back vocals that is devoid of shout or shrillness. If you don’t mind midrange recession, the Autumn won’t be disappointing. However, for those seeking more forward or energetic vocals – this ain’t it.
Then comes the treble, and here we have perhaps the only tonal oddity of the Autumn. The 5kHz peak is quite prominent and makes leading edge of cymbal hits sound a bit brittle. This presence region emphasis is needed to keep the Autumn from sounding overly dark but this also leads to over-crispness at times.
Upper-treble is well extended with resonances being heard well until 15kHz. The airiness is kept in check though so it doesn’t lead to fatigue.
Before getting into technicalities, let’s talk about the filters. The filters only increase or decrease the amount of bass but due to how we perceive sound, this change in bass markedly alters the presentation.
The normal filter is the one I found the most balanced, with the bass filter making things too bassy and the treble filter making the 5kHz peak even more prominent.
When it comes to staging, I found the stage width to be quite good. Everything is well separated, and the Autumn don’t sound cramped. However, stage depth is limited.
Imaging is also average with positional cues often being hazy. The saving grace here is the reproduction of microdynamics that allows you to delineate between instruments playing at differing volumes.
Finally, resolved detail is above average for a single dynamic IEM but the Autumn will be bested by a number of multi-BA or hybrid offerings in this range.
Compared to Final E4000
Final E4000 have been one of my default recommendations for a single dynamic driver IEM under USD $200.
In terms of build, the Final are no slouch with a similarly solid aluminium shell. Final went for a barrel shape and mmcx connectors but both IEMs are at equal playing field here.
Comfort and Isolation wise I think E4000 wins as they block more noise than the Autumn. Accessories are about par on both.
As for the sound, E4000 have a similarly bass-boosted, warm tuning but Final has even less emphasis in lower treble. This results in a tad darker tuning than the Autumn. Another noticeable change is the staging and imaging where the E4000 sound more expansive and accurate respectively.
Resolved detail is a bit better on the Autumn due to better upper treble extension. Macrodynamic punch is better on the E4000 meanwhile. Mids are also more engaging on the Final IEMs.
One advantage of the BQEYZ Autumn is the filter system that isn’t available on the E4000 at all. So if you want to change the tuning on the fly the Autumn will be better suited. E4000 are also more difficult to power, requiring better amping.
BQEYZ have tuned the Autumn fairly well. They didn’t just try to copy-paste an existing target curve and instead went for their own flavor of sound which is rarer to see these days. I do wish that the Autumn were a bit better in terms of technicalities, esp the imaging department. BQEYZ’s previous offerings were better in this regard so this one is a backward step.
Other than that, the Autumn are a solid pair of single dynamic IEMs, and on sale price they warrant a closer look.
