【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. Equipped with two ESS Technology DAC + amplifier integrated chips "ES9219MQ" in left and right independent configuration. Achieving both low noise, low distortion, and high output: The BTR15 uses ESS Technology's integrated DAC chip "ES9219MQ", with a total of two independent left and right DAC chips. The maximum power during balanced output is improved by approximately 40% compared to the previous model (240mW → 340mW), providing powerful drive power while independently supplying power to the DAC section of the integrated DAC chip and the headphone amplifier section. The design combines low noise and low distortion. 384kHz/32bit, DSD256, MQA full decoding playback possible with XMOS "XU316" with powerful processing power: BTR15 uses XMOS USB controller chip "XU316" and supports PCM384kHz/32bit in input from USB type C terminal. Supports 32bit, DSD256 (Native) playback. In addition, the powerful computing power of 16 cores enables full MQA decoding. *The USB DAC function supports two modes: USB Audio Class 1.0 mode, which does not require a driver, and 2.0 mode, which allows full spec playback. In the latter case, you will need to download and install the driver from the FIIO official website. Qualcomm's "QCC5125" is used as the Bluetooth receiver to achieve high connection stability: Equipped with Qualcomm's Bluetooth IC "QCC5125" installed in BTR15, AAC/SBC/aptx/aptx LL/aptx Adaptive/aptX HD It supports a wide range of audio codecs such as /LDAC. In addition to the 3.5mm single-ended output, it also has a fully balanced 4.4mm balanced output: In addition to the standard 3.5mm single-ended output, the BTR15 also has a balanced output with a 4.4mm terminal. With a fully balanced audio architecture that allows the ES9219MQ to operate left and right independently, each channel is driven by an independent DAC and amplification stage, boasting a maximum output of 340mW. Global parametric equalizer function that allows appropriate equalization regardless of the mode of use: The BTR15 is equipped with a "Global Parametric Equalizer (PEQ)" that is uniquely developed by FIIO and allows accurate equalization settings in both wireless and wired modes. Equipped with "Function". PEQ adjustment in Bluetooth mode uses QCC5125's DSP, and when used as a USB DAC, it is processed by XMOS XU316, but FIIO's unique interface allows common PEQ settings to be used in any mode. *If you enable/disable PEQ when using it as a USB DAC, the USB connection will be reset. Please adjust the volume and playback operations on your smartphone again. Equipped with a 0.96 inch organic EL on the front panel of the main unit. Easily check operating status and settings: The front of the BTR15 is equipped with a 0.96-inch, clear OLED display with a resolution of 96 x 96 pixels. The display is larger than the BTR5's 0.49 inch for improved visibility and can display pairing destination, connection status, call status, power status, encoding format, and volume. In addition, you can use this display and the hard buttons located on the side of the main unit to change the main unit settings, including EQ. 8 hours of continuous playback is possible with 2 hours of charging, and is equipped with care functions that ensure long-term use: With the built-in 550mAh, the BTR15 can be fully charged in about 2 hours and provides about 8 hours of continuous playback. is possible. Furthermore, it is equipped with multiple functions to care for the internal organs so that you can use it with confidence even after long-term use. Detailed main unit settings are possible with the FIIO app: The BTR15 has a larger display that makes it easier to configure the main unit, but when used in combination with the FIIO app (FIIO Music or FIIO Control app), the built-in parameters of the BTR15 can be adjusted easily. can be changed. A unique feature is the ability to adjust odd and even harmonic distortion. This allows you to create a sound that better suits your tastes. BTR15 is a headphone amplifier equipped with a Bluetooth receiver and USB DAC that has a 4.4mm balanced output and combines low noise, low distortion, and high output. It supports major high-quality wireless audio codecs such as aptX LL/aptX Adaptive/aptX HD/LDAC, and provides a high-quality wireless environment with approximately 8 hours of continuous playback. You can also connect a PC or smartphone to the USB Type-C terminal and use it as a USB DAC that supports PCM384kHz/DSD256.
