【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.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. FF3S is the latest model based on FIIO's intraconcave earphone FF3, which has been well-received for its uncompromising sound quality design, and has been significantly reduced in weight by changing the housing material, and is even easier to use with the use of a detachable cable. By combining FIIO's earphone development technologies such as a 14.2mm large-diameter driver, a newly designed drum-shaped housing, and the adoption of a sound pipe structure to enhance low frequencies, we have achieved a sound that breaks the conventional impression of intraconcave type earphones by expressing deep, sharp bass and glossy mid-high frequencies.
