1. Product Overview
2. Headphone technical characteristics
- High-efficiency HI-RES high-frequency moving iron unit from Knowles in the United States Designed to reproduce the rich and varied instrumental colors in recordings.
Composite full-frequency moving iron unit customized from Denmark Shengyang The high-performance moving iron unit with ultra-high resolving power allows every singing and string-picking to exude the deep emotion of the performer, and its excellent timbre restoration ability surpasses the tightness of ordinary moving iron units.
Undamped high-energy low-frequency moving iron unit from Knowles in the United States As Knowles' large-scale high-performance moving iron unit, it adopts an undamped response design to provide powerful sound output, and the dynamic details of low frequencies can be clearly reproduced, making every beat rich and crisp.
-
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.
-
3-WAY classic three-way circuit design Inheriting the classic three-way audio design idea, through precise frequency division circuit design, the four speakers can perform their respective duties, presenting a smooth and natural transition effect, allowing music details to be better restored.
-
Three-channel independent conduit and independent sound chamber The three acoustic channels of high, medium and low frequencies are all designed with independent acoustic conduits and cavities to reduce interference with each other and maintain their pure timbre performance.
-
Fully enclosed sound insulation design With the appropriate earplug cover and wearing depth, It can isolate up to about 26dB of external noise.

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.
