Description: The XDuoo XD05 BAL2 has gained significant attention as a portable audio decoder and headphone amplifier device, thanks to its advanced DAC chip, powerful output power, full metal body design, multiple interfaces, and high-capacity battery. A great tool for you to have, stable and practical, buy it! Features: MORE MUSIC DETAILS, MORE DIMENSIONAL FEELING: It uses two DAC chips, two chips to process digital music signals at the same time, whether your mobile phone, tablet or computer, whether it is MP3 or DSD format, it can fully show more music details. PLAY BACK A MORE HIGH-FIDELITY SOUND: Its THD+N is reduced to 0.00065%. Through twochips with original low phase noise crystal oscillator, combined with the new CPLD, the clock jitter is greatly reduced, making the music infectious. 1500MW OUTPUT POWER: Its output power reaches 1500mW, which makes the diaphragm of the headphone fully vibrate and improves the loudness of the harmonics. Even the high impedance headphone with 300ohm can fully show its music details, clarity, explosive power and elasticity, and fully enjoy the happiness brought by music. MULTIPLE INPUT INTERFACES: AES balanced input and 4.4mm balanced output, which is from digital input to headphone output are all balanced circuits, Let your balanced headphones have higher crosstalk and wider sound field, have a new experience. ENHANCE THE SENSATION OF THE BASS: If the bass of your headphone is weak, you can get a good bass feeling by turning on Bass and increasing the low frequency of the headphone. WIRELESS TRANSMISSION ALSO HAS GOOD SOUND QUALITY: Can be connected to various BT playback devices, support for high definition formats such as aptX_HD and LDAC, Let the wireless connection also have good sound quality. SUPPORT FAST CHARGING: Built-in 5000mah lithium-ion polymer battery, which can playback continuously for more than 12 hours. When it is indoors, it can be powered by external power (EXTE gear), so as to retain the battery power. When it needs to be carried out, its internal battery is also full. OLED SCREEN, DISPLAYING IMPORTANT INFORMATION: The OLED display clearly shows the audio sampling rate, input interface, power and DAC filter status, let you know at any time whether it works at its best.
