HiBy Digital Yume
1. Product Overview
:::info[HiBy Digital Yume is a co-branded headset between HiBy Digital, a sub-brand of HiBy Music, and Hatsune Miku. It uses newly optimized 10mm magnesium aluminum 2.0 high-energy dynamic coils to form pop music earplugs. It is specially designed for diverse J-pop music. Inspired by "exploring the rich possibilities of future music", it presents you with delicate and beautiful singing voices in dynamic rhythms. In terms of appearance, the visual elements of "Hatsune Miku" are integrated into the appearance design of YUME using the abstract design method of cyberpunk, and high-precision CNC cutting technology is used to carefully polish every detail of the original block of aluminum alloy. From the headphones to the cables, the theme colors and characters of "Hatsune Miku" are displayed, while providing an ergonomically designed and comfortable wearing experience for in-ear high-performance headphones. ]

2. Headphone technical characteristics
-
Dome shaped by summer synthesis of magnesium and aluminum molecules Making the diaphragm lightweight and rigid at the same time can improve the performance of timbre and details.
-
Polymer polymeric diaphragm suspension It can provide appropriate internal resistance factor and reduce unnecessary resonance.
-
High tension lightweight H.CCAW coil The dual magnetic circuit core provides a powerful driving force of 1.2T magnetic flux, and the high-tension lightweight H.CCAW coil provides a tensile strength of more than 150N/mm², which is 50% higher than conventional CCAW, making the headset easy to drive and with excellent control.
-
L.S.W. Low standing wave acoustic cavity and finely tuned airflow structure For dynamic speakers, it is crucial to balance the airflow to improve the naturalness of the sound and even the balance of the sound field. For this high-energy composite speaker with a 10mm magnesium aluminum dome, we reconstructed the L.S.W. low standing wave metal rear cavity and finely adjusted the air intake volume and airflow opening to improve the dynamics of the speaker and make the listening experience more open.

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.
