HiBy Yves+
I. Product Overview
The HiBy Yves+ features a gear-shaped exterior. After countless adjustments and meticulous engraving, it is refined just as carefully as our tuning of the micro dynamic driver. The Yves+ is a union of refined metal craftsmanship and warm sound—tough as iron on the outside, moving sound within.
II. Earphone Technical Features
- Newly designed 7mm micro dynamic driver, balancing sound detail and ample density
In the acoustic design of earphones, refining acoustic volume has always been a matter of every inch counting, and the design of micro dynamic drivers is like dancing on the edge of acoustic limits. The 7mm micro dynamic driver speaker redesigned for Yves+ retains the compact size of a micro dynamic driver, leaving more malleable space for the acoustic chamber and fit, while also balancing rich sound detail and ample sound density.
- Beryllium-plated composite diaphragm, greatly improving the micro dynamic driver's transient performance
We spared no expense in selecting metallic beryllium as one of the diaphragm composite materials for this micro dynamic driver. As the material with the fastest speed of sound among metal elements, beryllium can reach up to 12,890 m/s. It also has an extremely low atomic weight, light mass, and an extremely high Young's modulus. It is widely used in high-end acoustic fields and provides outstanding improvement to diaphragm transient performance.
- Repeatedly adjusted diaphragm material ratio, further improving diaphragm transduction consistency
After many comparisons and repeated adjustments, through a magnetron sputtering process, we precisely control the metallic beryllium on the Yves+ diaphragm so that its thickness does not exceed 2 μm. While greatly improving diaphragm rigidity, it retains the diaphragm's overall natural elasticity and improves the dynamic driver's frequency bandwidth and consistency. Whether it is delicate treble detail, natural and smooth vocal timbre, or powerful bass performance, all can be fully presented.
- High-magnetic-force driver core, letting the tiny dynamic driver core easily release great energy
Because the diaphragm area is small, micro dynamic drivers find it difficult to simultaneously deliver powerful energy and excellent detail. We specially use an N52 strong magnetic core to double driving efficiency, allowing the Yves+ high-rigidity beryllium-plated composite diaphragm to achieve higher transduction efficiency and more easily release the details in music.
- L.S.W. low standing wave acoustic chamber, making the micro dynamic driver breathe more smoothly
For dynamic driver speakers, using balanced airflow to improve the naturalness of timbre and even the balance of the soundstage is crucial. For this 7mm beryllium-plated composite micro dynamic driver, we designed an L.S.W. low standing wave aluminum alloy rear chamber, finely adjusting airflow in and out, making the speaker breathe more smoothly and the listening experience more open.
- High-purity OFC HiFi cable, lightweight and skin-friendly wearing experience
The lightweight and skin-friendly high-purity OFC HiFi cable not only provides HiFi-grade original sound transmission, but also reduces cable weight and greatly reduces the impact of the stethoscope effect.
- 0.78mm 2-pin detachable cable design
With the more compatible 0.78mm 2-pin detachable cable design, Yves+ gives users unlimited cable pairing possibilities.

V. Wearing Method
- This earphone and cable must be distinguished by left and right sides. L stands for left ear and R stands for right ear. Both the earphone cavity and cable have clear L/R markings. Please make sure to connect them correctly during use. If the stethoscope effect occurs while wearing, you can wear them over the ear.
VI. HiFi Earphone Wearing Precautions
- When wearing or storing the earphones, avoid high temperature, low temperature, humid, or dusty environments to prevent damage to the earphones or impact on sound quality. It is recommended to store them in a dedicated moisture-proof storage pouch to reduce damage.
- Do not soak the earphones in water. Avoid liquid entering the driver or cable interior. If water stains appear after use, dry them promptly.
- Avoid excessive pulling or bending of the earphone cable, which may cause internal wire breakage.
- Avoid dropping the earphones heavily to prevent internal parts from loosening.
- When connecting to a device, do not forcefully insert or remove the plug to avoid damaging the plug or the device port.
- If worn for a long time, let your ears rest for a while to avoid ear fatigue and hearing damage. Also avoid listening at high volume for long periods, which both protects your hearing and better preserves driver performance.
- If the earphones malfunction (such as sound distortion, no sound, poor contact, etc.), do not disassemble or repair them yourself. Contact the brand's official after-sales service to avoid affecting the product warranty.
- When cleaning the earphones, use a dry, soft cloth. Do not use corrosive cleaners such as alcohol or acetone to avoid damaging the driver housing and cable sheath. Clean the ear tips regularly to keep them clean and hygienic.
