【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.
Yumekai - Golden Ages × Kiyono Yasuno MOONDROP × YASUNO KIYONO: A new design inspired by Kiyono Yasuno, and a refreshing protective case in similar colors is also included. Additionally, a comic-style acrylic character stand and Kiyono Yasuno postcard are also included. Special voice guidance by Kiyono Yasuno is included, and you can freely switch between Japanese and Chinese versions. Five levels of tuning can be freely switched, and Kiyono Yasuno's custom tuning has been specially added.
13mm ultra-linear full-range planar drive driver: Equipped with a new 13mm planar drive driver that uses an annular magnetic circuit and a diaphragm. A magnetic circuit array consisting of multiple high-performance N55 magnets and an annularly arranged drive circuit work together to create a much larger effective vibration range than a dynamic driver. In addition, the innovative dual edge system significantly reduces distortion, and the uniform stiffness structure further reduces splitting vibrations. This results in amazing performance for completely wireless earphones. Furthermore, the conversion efficiency is 4 times higher than a dynamic driver of the same size and 10 times higher than a 14.5mm planar drive driver. Compared to planar drive drivers of the same size, it has significantly lower nonlinear distortion, and can demonstrate a wide dynamic range with low power consumption and low distortion.
LDAC High Resolution Lossless Wireless Transmission & LC3 Low Latency High Fidelity Wireless Transmission (Standard): The "Yumekai x Kiyono Yasuno" collaboration earphones support the widely adopted high quality wireless codec "LDAC" and can transmit 24Bit/96kHz audio signals at a maximum bit rate of 990kbps, resulting in a wide dynamic range and excellent detail. In addition, it supports the LC3 codec of the next-generation Bluetooth audio standard "LE Audio", and when connected to an LC3 compatible device, it can simultaneously achieve much lower delay and high fidelity than conventional Bluetooth.
The "Yumekai x Kiyono Yasuno" collaboration earphones do not use a feedback method, but only use a feedforward method, which is more difficult to tune, in order to suppress the deterioration of sound quality due to noise canceling. By combining a new high-end SOC chip with excellent acoustic design, and repeated tuning by professional acoustic engineers, we have achieved both excellent noise canceling performance and sound quality. The external sound capture mode has further evolved to reproduce environmental sounds and human voices in more detail and naturally.
[12 Month Product Warranty & Package Contents]: This product is covered by a 12 month warranty period from the date of shipment. During the warranty period, we will repair, replace, or refund free of charge for any malfunctions that occur under normal usage conditions. Package contents: Earphones, charging cable, earpieces (1 pair each of S/M/L), protective case, instruction manual, warranty card, inspection certificate, product guide, thank you card, character stand (acrylic), postcard
4 times the conversion efficiency of a dynamic driver of the same size & 10 times the conversion efficiency of a 14.5mm flat drive driver: Compared to a flat drive driver of the same size, the nonlinear distortion is much lower, and it can demonstrate a wide dynamic range with low power consumption and low distortion.
55ms low latency game mode: Equipped with music/game dual mode, allowing you to switch between two connection modes in Bluetooth connection (AAC/SBC). "Music mode" transmits a high bitrate signal, and "Game mode" reduces the delay to 55ms, providing a more comfortable gaming experience.
