Features With an OLED display, real time display digital information flow. The USB receiving chip adopts XMOS's XU316, supports up to PCM32 Bit/384 kHz, DSD256 and MQA 8x. Use USB OTG cable, Supports IOS and Android system mobile phones or players. Bluetooth 5.4, supports aptX、aptX_HD、aptX_AD、LDAC、LE Audio formats. DAC chip uses CS43131, with better decoding performance, extremely low noise and higher resolution. It adopts 3X Clock structure design, ensures the DAC to obtain a first class sound performance. 3 correspondence level clocks are high precision, individually control multiple of 44.1KHz, multiple of 48KHz and USB signal transmission, dedicated for USB asynchronous transmission, and reduced Jitter to undetectable level. The amp circuit adopts the OP+BUF architecture, the output power reaches 750mW, can easily promote many kinds of headphones. The amp chip can be replaceable by yourself, different chips bring different sound quality. It has a bass boost switch to meet different listening needs. It has a gain switch and can adapt to headphones with different impedances CONVENIENT TO CARRY It is very convenient whether you carry it with you at home, in the office, on business trips or during travels, allowing you to enjoy high-quality music anytime and anywhere. POWERFUL DECODING ABILITY It has the USB DAC function, which makes it convenient to connect via USB to various devices, such as computers, smartphones, tablets and smart music players, then output higher-quality music signals. It has a very strong decoding ability and can decode high-definition formats, such as PCM32Bit/384kHz, DSD256, and MQA with 8x unfolding. This allows you to feel more musical details brought by the high-definition formats, such as the subtle sounds of musical instruments that are usually difficult to hear. LE AUDIO BLUETOOTH 5.4 The new generation of Bluetooth 5.4 technology features faster transmission speed. It supports the new generation of LE Audio Bluetooth coding protocol, which has lower latency and better sound quality, making it well worth experiencing. It supports LC3, aptx_Lite, and aptx_AD formats. It continues to be compatible with traditional Bluetooth coding protocols and supports a variety of high-definition formats, such as aptX, aptX_HD, aptX_Adaptive, aptX_Loss-less, LDAC and other formats. POWERFUL DRIVING ABILITY The output power of the headphone jack reaches 750mW per channel. Coupled with the high and low gain adjustment, it can deal with various types of headphones very well. EXCELLENT PARAMETERS The THD reaches 0.0006%, which ensures that the audio signal maintains its original tone during the amplification process, reducing distortion and noise. The SNR reaches 124 dB A high SNR means low background noise and a purer audio signal, allowing users to hear musical details more clearly REELY SWITCH BETWEEN PORTABLE & DESKTOP MODE It has two power supply modes: DC and battery. When you need to use it flexibly and move around, you can use battery power supply, which is convenient for listening to music anytime and anywhere. When it is used in a fixed position on the desktop, you can use DC power supply, and the driving force will soar. At the same time, DC power supply greatly reduces the battery load and effectively extends the battery life. EQ ADJUSTMENT When watching a movie and you want to experience the feeling of explosive roars and thumping bass, you can turn on the bass in the setting in the menu settings. DIGITAL VOLUME ADJUSTMENT The sensitivity of modern HIFI headphones is extremely high, which undoubtedly poses stringent requirements for the precision of volume control. Therefore, we adopt digital volume adjustment to solve the problem of left and right channel imbalance of traditional potentiometers at low volumes, ensuring that the left and right channels can be perfectly synchronized at every volume level. With 99 fine-grained volume adjustment levels, for headphones of any impedance and any sensitivity, you can find the "exclusive volume" that suits them. SIMPLE TO CHANGE AMPLIFIER CHIP For players who pursue the ultimate audio experience, it is really fascinating to be able to adjust the sound style with their own hands. Therefore, the operational amplifier chip in our design is removable and replaceable. Without the need for professional tools, you can easily replace the operational amplifier chip with just your hands, and experience the distinct sound quality brought about by different chips. CAREFULLY SELECTED MATERIALS We have selected and tested the materials that affect the sound quality numerous times, all with the aim of presenting a better sound quality We adopt the professional grade DAC chip CS43131 as the decoding chip because it has better THD, higher SNR and higher resolution. We use the audio specific capacitors of internationally renowned brands such as NICHICON and ELNA because they have very low ESR, very small leakage current, and good temperature stability, and perform extremely well in terms of their impact on sound.
