【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Forteza features a hybrid design using one high-mid balanced armature (BA) + 10mm midrange dynamic driver (DD) + 10mm base DD. This 1BA + 10mm DD + 10mm DD combination provides full sound from 20Hz to 20,000Hz. Furthermore, by using two different dynamic drivers in combination with the BA driver, a significant improvement in sound texture and timbre is achieved.
Forteza features a 3-way passive crossover system tuned for a rich, intense sound signature. The bass response is thick and packs an impactful punch. The slow decay gives the bass a more textured, rumbling sound, allowing bass guitar lines to really shine. The midrange has also been adjusted to sound more colorful and warmer, giving vocals and instruments a thicker sound. These characteristics are perfect for people who want a richer sound rather than a flat, neutral sound signature. The treble response is carefully tuned and paired with lows and mids to prevent a dull sound signature. The treble response closely matches the target's preference curve, allowing for crisp expression and full micro-detail retrieval.
Forteza is equipped with our established in-house drivers for high quality sound. Using drivers that have proven successful in past models, the combination of these drivers ensures maximum efficiency and quality. For example, the composite 10mm dynamic driver system provides superior bass response due to its careful diaphragm configuration and driver size. By layering a 6mm low-mid DD on top of the 10mm DD, the low end is textured with excellent imaging ability. Additionally, the single BA driver has been tested with excellent SPL to THD ratio and excellent tonal characteristics across the frequency range. The use of in-house drivers ensures optimal technical and acoustic performance based on direct implementation.
Forteza comes standard with a detachable cable with a 0.78mm 2pin connector. This cable can be swapped out with other cables to customize your experience or extend the life of your IEM. Please be careful if the earphone noise is created by a generic size and your ear holes are too small. We also make earpieces of each size in a universal size, so please contact us before purchasing.
