HiBy Project Ace JP
1. Product Overview
2. Headphone technical characteristics
- Redesigned 12mm large-diameter moving coil element The area of the 12mm moving coil unit that pushes air is 1.44 times that of 10mm and 2.25 times that of 8mm.
Using larger-diameter speakers than common IEMs, it can simultaneously display accurate high-frequency sound and richer low-frequency and mid-frequency details. Redesigned speakers and internal sound chambers also allow different musical elements to be better displayed.
-
Highly rigid titanium diaphragm with new technology As one of the pioneers of Asian music trends, Japan continues to export and create various types of music to satisfy music fans with different tastes. Therefore, we re-developed the moving coil diaphragm material based on the ProjectAce standard version, using multiple PVD+ processes to accurately attach more than 60 layers of titanium gold compound particles to the PEEK substrate. This not only improves the rigidity of the diaphragm, but also further improves the consistency of the diaphragm movement, making the extension of mid-to-high frequencies smoother.
-
High-end PEEK as the base material of the diaphragm It provides excellent internal friction performance for this moving coil unit, allowing the inertial amplitude and duration of the entire moving coil to be fully controlled. No matter high, high or low frequencies, it can show rich and delicate musical details. .
-
1.2T powerful dual magnetic core In order to achieve a more efficient driving effect for the diaphragm with excellent high rigidity and high internal friction performance, we redesigned the magnetic circuit core and magnetic gap of the moving coil, allowing the dual magnetic core to provide high-efficiency magnetic force of up to 1.2T (Tesla), allowing Project Ace JP to achieve excellent electro-acoustic conversion efficiency.
-
T.B.A.C. and multiple independent vocal chambers We first designed dual independent sound cavities for the new dynamic unit to specifically enhance the dynamic details of the mid-range and low frequencies. Then we continued to combine FAudio’s patented technology "T.B.A.C." (triple acoustic cavity) and adjusted the new airflow guidance model to ensure efficient airflow performance and natural sound playback effects.
-
New generation T.B.A.C triple acoustic cavity
Cavity 1 We specially designed independent dual inner cavities for the new 12mm large-diameter dynamic driver, which can more accurately control the inlet and outlet airflow of the dynamic driver to find the best balance between efficient driving and reducing standing waves.
Cavity 2 The metal structure strengthens the rigidity of the entire unit to avoid excessive resonance, and adjusts the airflow through the air holes in the rear cavity, making the tuning full of detail and power at the same time.
Cavity 3 It effectively releases excess air pressure in the ear canal while stabilizing the air flow, providing an endless supply of air to the unit, enhancing the clarity of the overall sound, and making the layered performance of the titanium diaphragm more distinct.

5. How to wear headphones
- Both the left and right sides of this headset and its wire need to be distinguished. L represents the left ear and R represents the right ear. The L/R mark of the headset is located next to the earphone vent. The L/R mark of the wire is located inside the 2-pin double-pin male connector. The correct connection method between the headset and the wire is as follows:
- After connecting and assembling the earphones, wear them around the ears. The correct wearing method is as follows. When wearing, please choose an earphone cover of the appropriate size according to your ear size to ensure a tight and comfortable wearing feeling. This earphone is an in-ear earphone. Poor sealing will cause low-frequency loss, reduced sound quality analysis, etc., affecting the listening effect. Please wear it normally.
6. Things to note when wearing HiFi headphones
- When wearing or storing headphones, please avoid high temperature, low temperature, humid or dusty environments to prevent damage to the headphones or affect the sound quality. It is recommended to store them in a special moisture-proof storage bag to reduce damage.
- Do not immerse the earphones in water to prevent liquid from entering the unit or cable. If there are water stains after use, wipe them dry in time.
- Avoid excessive pulling or bending of the headphone cable, which may cause internal breakage of the line.
- Avoid dropping the earphones hard to prevent internal parts from loosening.
- When connecting the device, do not insert or pull out the plug forcefully to avoid damaging the plug or device interface.
- When wearing it for a long time, you need to let your ears rest for a while to avoid ear fatigue and hearing damage; at the same time, avoid listening at high volume for a long time, which can not only protect your hearing, but also better preserve the unit performance.
- If the earphones malfunction (such as sound quality distortion, silence, poor contact, etc.), please do not disassemble and repair it yourself. You should contact the brand's official after-sales service to avoid affecting the product warranty.
- When cleaning the earphones, please use a dry and soft cloth to wipe them. Do not use corrosive cleaners such as alcohol and acetone to avoid damaging the unit casing and wire sheath. Pay attention to regular cleaning of the earphone covers to keep them clean and hygienic.
