[Machine Translation] Unleashing the potential of headphones. Ultimate reality brought about by a clear sound image. The acoustic technology we have cultivated over many years pushes out high-density audio signals with force, improving the rise and response of the sound. The resolution of low to high frequencies is further enhanced. The USB Audio IC of SAVITECH's BRAVO-HD SA9227 is used. The USB Audio IC of SAVITECH's BRAVO-HD SA9227 maximizes the potential of high-resolution sound sources. *The I/V conversion circuit uses TI's LME49720, an ultra-low distortion and low noise operational amplifier. A high-capacity lithium polymer rechargeable battery that supplies sufficient current to every corner of the circuitry transmits all the power of the sound without loss of signal-to-noise ratio. The volume control is designed for ease of use as a portable device, for example, to prevent accidental operation. (Product Specifications and Description) / The power stage is equipped with a discrete circuit of our original design. / The industry's first use of NJR's MUSES 8832 operational amplifier in the pre-stage. (According to Audio-Technica research as of August 2014) / Supports PCM 32~384kHz/32bit and DSD 128/64*. The highest class DAC, ES9018K2M from ESS, is used. / Transparent mid-high frequency reproduction with minimal unwanted distortion. / High-capacity 3500mAh rechargeable battery with ample current supply. Aluminum machined volume knob on the side panel. / 5-step sampling indicator (lights only when connected digitally). (Two rubber bands and a rubber mat are included for portability.
