This article is a translation of the following Japanese article.
In this article, we're going to take a look at Fidue Asteroid. Fidue is a Chinese brand of IEM manufacturing that is known for its high quality products. There is a flagship model called Fidue Sirius that is very well known in this brand, and the recently refined Fidue Sirius Mk-II has become a hot topic.
Fidue Asteroid is a hybrid driver earphone that combines a piezo and dynamic driver, created by Fidue, one of the most technologically advanced manufacturers in China, to provide a high quality Fidue sound at an affordable price.
Basic specifications
- Frequency responce: 8hz-41kHz
- Impedance: 32Ω
- Sensitivity: 110dB

Unboxing
This is a better than standard quality package for this price range. It is disappointing that the carrying case is in a drawstring bag format and the sewing thread is a bit poor and doesn't seem to be very durable, but the two pockets could be useful for carrying accessories as well. There are more accessories, but the unpacking experience is simple.
The build quality of the unit is very high, which is typical of Fidue. The main body of the earphones is also a sturdy metal build with a rounded design that is comfortable to wear. The build quality of the cable is also high and easy to handle.
Please refer to HiFiGO's review of the package for a more detailed atmosphere.
Fit
The main body of the earbuds has a rounded design that is unique to Fidue, and also has a wavy design on the faceplate, which is also typical of Fidue. They're small, fit nicely in your ears and are smooth to wear.

Overall, it has a fairly flat sound signature, which could be described as a bit of a U shape. The lower midrange is recessed but the upper midrange is forward and the midrange sounds clear and transparent.
The low end has good layering and a rather straightforward depth to it. There is a moderate weight, and the kick is clear and tends to be tight with good sharpness. The bass is also rather clear, but I feel that it is not as thick as it should be. There is some heat in the lower low end of the range, but it hardly bleeds into the midrange because the lower midrange is clean.
The midrange is transparent, fairly clean and rather tight. There is an emphasis in the vocal band, so the vocals sound quite bright up front. There is very little sense of burial, even in rock songs with a noisy low frequency. The vocals sound brighter and more energetic with an upward tendency, and are moderately extended with a slightly upbeat tone. It has a slightly coquettish and flirtatious flavor, and sounds slightly younger with a glossy feel. If you like glossy vocals, I recommend these earphones, and you will be able to hear dynamic vocals in pop star songs and bright anime songs to your heart's content. However, depending on the song, the body of the music may become a little thin and the consonants may be sharp, and the T and S may sound a little irritating. The midrange is separated from the low range and a little buoyant, so some people may hear the sound gathered in the high range in terms of sound density.
The highs are probably handled by the piezo drivers, but they have a tight, piezo-like sound. The mid and high frequency peaks seem to come over the vocals a bit, and there's a bit of congestion around the top of the vocals. However, the vocals are firmly prioritized, so the sound isn't so crowded. Personally, I find the clues to be rather enjoyable. The glare feels a little bit more pronounced, the edges of the acoustic guitars and so on are rather noticeable, and there's also a moderate snappiness to the snare. The highs maintain a moderate distance from the mids, emphasizing details and edges while complementing the presence of the mids, and the separation is quite good.
I think the overall range is good and the verticals sound rather well organized. The low end is deep and the high end is a little closer to the midrange, but the upper midrange is clearly dominant in terms of power, and the sound is brighter and clearer to enjoy vocals and midrange sounds. It seems to be a good match for bright female vocal songs in particular, and you can enjoy EDM comfortably.
Recording signature
Please refer to the following for the basic principles of recording signatures and how to enjoy them.
The recording signature is posted for advisory. Free sound field adjustment is added. The source is FiiO M15 and the gain is high. The eartips used are the "Standard silicon S (Single flange) size".
The music used in the recording signature is from the game maker Nippon Falcom, which I love.
