Brining wireless freedom to the world of high sound quality, the AK XB10 uses aptX™ HD— the latest Bluetooth codec of Qualcomm— to receive high-quality data wirelessly, and faithfully play back with incredible clarity and detail. With superior compression, low computational cost, and low transmission delay, this aptX™ HD codec is capable of transmitting up to 24-bit/48 kHz audio that is faithful to the original audio file.The AK XB10 is also equipped with a dedicated DAC for the best digital-to-analog signal conversion that significantly improves Signal-to-Noise Ratio (SNR) and Total Harmonic Distortion (THD). Rather than simply amplifying the audio signal, the amplifier was designed with a ”driving” concept to amplify weak signals and power difficult to drive high impedance headphones. AK XB10 was shaped to mimic the appearance of the scattering of light from a star. The top surface is split into quadrants, which allows easy operation with just a touch of the hand. And thanks to the clip on the back, when you want to enjoy your music on the go, simply mount the clip and effortlessly attach it to your shirt or bag. Compact, portable, and powerful, the AK XB10 delivers a distinctive difference in sound from conventional Bluetooth products.
