Product Details
  • MFi Certified, Ultra Small High Resolution DAC/AMP, USB-C Connection: This ultra-small DAC / AMP, equipped with a φ0.1 inch (3.5 mm) jack that can easily enjoy high-resolution playback on smartphones and PCs. The Japan Audio Association has acquired a high-resolution sign, and the bit rate of music playback is supported up to 32bit/384kHz, which has approximately 17.4 times the amount of information from CD sound source (16bit/44.1kHz). DSD playback can be up to 5.6MHz DoP playback
  • Equipped with the ES9270C for high audio quality: Equipped with ESS Technology "ES9270C" as SoC. It is equipped with the company's patented technology "Hyperstream DAC" and "Time Domain Jitter Eliminator Circuit" to achieve high levels of audio characteristics. In general, audio characteristics are indicators of "static characteristics" which are the output characteristics obtained when input simple signal waveform (sine wave or square wave) under rated loads. However, during actual music playback, the amplitude and frequency of the input signal waveform is not constant, resulting in non-cyclic constant noise and worsening characteristics. The Hyperstream DAC is a unique noise shaving technology that eliminates constant noise in the "dynamic characteristics" that are the output characteristics of music playback. In addition, the "Time Domain Jitter Eliminator Circuit" allows for more precise signal conversion by compensating the vibrations on the time axis of an audio master clock that can occur during D/A conversion. Plays stable and crystal clear sound in position
  • [Energy saving and high fidelity G-class amplifier] The ES9270C is equipped with a G grade amplifier. When the audio signal level is low, such as the music you play, use the lower power voltage, and the signal level increases, it will automatically switch to the appropriate power voltage. By working efficiently according to the size of the signal level, it is able to optimize the power usage of the connected terminal, and it is energy-saving and capable of playing music at all times
  • Compact aluminum housing for any connecting device: The housing material is made of lightweight and high rigidity aluminum. It has a simple profile that goes well with any audio device to connect, yet has a refined texture with attention to detail and texture. The total length is only 3.9 inches (10 cm) and is extremely compact
  • 【Compatible with Various Devices】 Equipped with a USB-C plug, it can be used with devices that support iPad OS 15, Android OS 12, MacOS 13.2, Windows 10 and above. Enjoy high quality music playback at any time in a variety of settings such as smartphones and PCs
  • (Certified to work with the iPhone 15 series) You can enjoy high-quality sound playback even with the iPhone 15 series. As of September 2023
  • Note: Radius products are inspected prior to shipping, firmware updates and regular recharging procedures. As such, there may be some temporarily opened products, but this is a unused product and does not affect the quality. Thanks for your understanding
