OverviewThe Blue Mix-Fi are powered headphones that innovate on the traditional closed-back, over-ear headphone design with the incorporation of an internal all-analog audiophile amplifier. This allows the headphones to work well with low output sources such as smartphones, tablets, and other mobile devices.The headphones can operate in passive mode without the headphone amplifier, in active mode with the amplifier, or in bass boost mode, which adds additional low-frequency energy to the signal. The addition of an integrated amplifier within the headphones allows for the use of 50mm fiber-reinforced dynamic drivers to deliver a frequency response of 15 Hz to 20 kHz, making them suitable for everything from professional music production to recreational listening. With E10K USB DAC Headphone Amplifier from Fiio is designed to improve your laptop's audio output quality via its PCM5102 DAC chip and is capable of handling PCM files in up to 24-bit, 96 kHz resolution.
