The K1 utilises Savitech SA9023A USB receiver to decode USB audio. Also TI's high fidelity, low noise PCM5102 DAC Chip which outputs to the TPA61332A headphone driver. It's self-muting function can greatly reduce power on/off transients, giving a hassle-free music experience.
Connect your K1 to a computer via the supplied USB cable to obtain instant music improvements. The K1 has no battery and therefore does not require charging. It also operates via plug and Play, thus requiring no drivers to be installed.
