    All portable devices have a controller chip and some controller chips have a DAC built-in to save cost and power. Normally, hi-fi grade music players use a separate DAC chip because most built-in DAC do not sound good. An independent DAC chip consumes a lot more power than a built-in DAC. Good sounding hi-fi portable players are bulky in size, whereas small size portable players - with a DAC built in controller chip- sound sucks.
    HiFiMan has spent years on a crazy project. SuperMini. We selected a low power consumption controller chip with a DAC built-in. After heavily modifying firmware and drivers of decoding/Audio/DAC, we have changed its original sound signature and achieved an amazing result: a sound signature similar to our flagship hi-fi music player HM901. That is why SuperMini sounds transparent, warm, sweet and punchy. It is one of the smallest portable hi-fi devices. Its battery life is 22 hours.

    Full Size Headphones? Not Even a Challenge
    The swing of output voltage is 4.2V peak to peak, capable of driving most full size headphones
    The output power can reach 320mW which can perfectly drive the HIFIMAN HE400i and HE400S planar magnetic headphones.

    Thanks to its power-saving design, the SuperMini is built with 8 op-amps and it can reach output 4.2V @ 32 ohms. That is powerful enough to drive most headphones in the market.

    The body is carefully crafted, CNC machines from a solid block of aluminum alloy.
