gift with Headphone amplifier K7 with FIIO DAC [Cross logo] built-in (FIO-K7-B)

【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. The K7 is a compact stationary USB DAC/headphone amplifier that is the same size as the K5 Pro ESS, but it is equipped with AKM's latest DAC chip "AK4493SEQ" in a dual configuration that operates one for each left and right channel, and the audio circuit is top of the line. Adopts the same perfectly balanced design as the model K9 Pro ESS. This is the latest model that supports balanced headphone connections, which has been requested by many users. By adopting the same "THX-AAA 788+" technology as the K9 Pro ESS for the headphone amplifier circuit, it accurately depicts the musical details contained in the signal without compromising it, while also delivering maximum performance from a compact housing. Demonstrates an amazing drive power of 2000mW. *A free microfiber cleaning cloth with the FIIO logo that is convenient for cleaning! *It's safe.
