Features of ISN Audio H30
- The ISN Audio H30 is a hybrid ear monitor with two balanced armature drivers and one dynamic driver.
- It uses a 9.2mm beryllium-coated dynamic driver for bass, a Sonion BA for mids, and a Knowles BA for highs.
- It has an impedance of 18 ohms, sensitivity of 112 dB, frequency response of 20-20 kHz, and uses MMCX connectors and gold-plated plugs.
- A 1.2 meter cable is included.
The ISN H30 is a newly released IEM from ISN, a manufacturer of cables and IEMs. ISN has released five IEMs so far, and the H30 is considered to have the most neutral sound of them all. However, it is not a completely neutral sound; this is achieved by cutting the high frequencies, reducing the heavy bass, and emphasizing the midrange. In terms of price range, it is positioned at a lower price point than the H50. It also uses an MMCX connector and features a chrome nozzle made by a 3D printer. Note that the H30 comes with an 8-conductor OCC copper cable, which can be connected in 3.5mm, 2.5mm balanced, or 4.4mm balanced. The shape is also distinctive, with a semi-custom design.
ISN has five different sounding IEMs, the H40, D10, EST50, H50, and D02, each with a different sound, allowing ISN to meet the needs of a wide variety of users The H30 is the most different sounding IEM that ISN has released to date The H30 is notable for having the most different sound of all the IEMs ISN has released. The H30's semi-custom shape also makes it easier to fit in the ear. In terms of price range, this IEM is less expensive than the H50 and is recommended for users seeking high-quality sound.

Sound quality description
In this review, I use the standard eartips size L and drive it with the FiiO M15.
The ISN Audio H30 has a neutral-conscious, full midrange sound signature.
Please see here for detailed reviews on sound quality.
Lows / Bass
The ISN H30's low frequency range is quite deep and linear.
The bass drum is not lacking in thickness and weight, and the tightness is reasonably good and the sense of rhythm is easy to understand, but the sense of presence is a bit weak.
The electric bass also has enough blackness, but I would like to see a little more extension.
In terms of volume, it will satisfy bass lovers, but heavy bass fanatics will prefer a deeper sound.
The midrange of the ISN H30 seems to have been tuned with neutrality in mind, but it lacks linearity.
The lack of linearity in the midrange can easily lead to a cloudy feeling in the center, the most important part of the music, and is not welcomed by audiophiles who are faithful to the original sound. It also results in a significant amount of distortion, which can lead to a lack of transparency.
As a result, the H30's midrange has a strong sense of muddiness due to stagnant resonance and poor separation from the background, and the center area is out of focus and strangely difficult to hear.
On the other hand, the way in which the sound is not clearly heard, but rather blurred and blended into the background and gently echoed, is pleasant and mild to the ear, and may be said to be suitable for listening to music immersed in the music.
Vocals sound a bit pushed to the forefront.
Highs / Treble
The H30's highs are well tuned with definition in mind, providing ample detail and finesse.
Compared to the warm and fuzzy midrange, the highs are sharp, detailed, and excellent in detail, with high transparency and resolution. Cymbals are a bit dry but sound crisp and tight, adding spice to the music, and guitars and snares are tight and rock sounds very lively.
On the other hand, it lacks linearity, so strings and woodwinds tend to sound a bit metallic and drawn out, and while dynamism is emphasized, it lacks a natural freshness. However, the sense of localization is not bad.
Sound quality general comment
- Original Sound Fidelity: A
- Recommendation: A-
- Personal preference: A-
The ISN Audio H30 is close to neutral on a macro level and seems to be well balanced. However, the overall linearity, or consistency of the sound image, is lacking, and the overall clarity is not good, so it is not really suitable for audiophiles.
In particular, the strong muddiness in the midrange is not highly appreciated by audiophiles. For listening while working or taking a break, the fuzzy, ear-friendly feel may not be so bad. However, if you are familiar with earphones with excellent midrange, such as the TinHiFi C2, you probably won't find the H30's muddy midrange very interesting.
On the other hand, however, its resonant midrange gives a unique sense of immersion, and the clear high frequency range gives a good impression, making it interesting for its unique musical expression. The overall balance is good, so while the quirks are a bit strong, they do not feel too unnatural.

The ISN Audio H30 has a resonant, rich midrange and an immersive sound. They are quite attractive listening IEMs for listeners who value the spatiality with which music resonates. The overall balance is also close to neutral and well-defined, and no shortage of detail or subtlety can be detected. However, they are not the first choice, at least not for audiophiles who value transparency, especially in the midrange.
