【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. To prevent ear damage from accidental volume adjustments, the device features a volume limiting function that sets the sound pressure level to a maximum of 85dB*. *Based on the European safety standard "EN71-1" for toys. 85dB is approximately the same volume as the sound inside a moving train. It features a small and lightweight design that fits easily on a child's head. The headband, made of soft material, has seven numbered markings for easy length adjustment, and the adjuster is designed with minimal gaps to prevent children from pinching their fingers while wearing it, demonstrating consideration for the child's ease of use. Designed to prevent the cable from getting caught while using the headphones, once paired with a device, simply turning on the power will automatically establish a wireless connection. It also supports the Bluetooth standard Ver. 5.0/Power Class 2, ensuring a stable wireless connection. It provides approximately 16 hours of continuous playback with its built-in battery.* *: May vary depending on usage conditions. The package includes original stickers (A7 size x 4 sheets) featuring alphabet letters to represent your initials and a variety of designs. You can freely stick your favorite stickers on wide sliders and other surfaces to create your own unique design.
