Pocket HiFi C4 shell wood produced from the North American black walnut, they are the best once the title of Royal walnut. This wood texture is not only thorough, smooth and delicate, glossy, ring clear, and sometimes with wavy or curly tree pattern to form a pleasing decorative patterns. Due to the unique wood grain, each player is unique.

ColorFly C4 is a true pocket hi-fi, the first portable music player to feature 24bit/192kHz playback with a true audiophile design that will properly drive audiophile quality headphones without the need for a separate headphone amplifier. A truly astonishing portable music player, the C4 is also ideal as a main hi-fi source and sounds simply stunning with all variety of suitable amplifiers and hi-fi systems.

Easy to use, simply drag and drop your music files onto the flash based 32GB internal storage space or onto a micro SD card accepted into the bottom of the unit (not included), allowing you to expand the storage space even more. The Colorfly truly is quick and simple high end audio on the go!

The Famous DAC
The excellent sound quality and support for 24bit/ 192kHz is possible thanks to a single Hi-Fi DAC (Digital-to-Analogue Converter).
The ColorFly team decided to use the CIRRUS logic CS4398, a high-end chipset usually only found in top-of-the-range Hi-Fi components costing many thousands of pounds.
This DAC offers outstanding levels of performance with excellent dynamic range up to 120dB and the ability to decode 24bit/192kHz audio for stunning sound quality.

A Touch of Volume Nostalgia
Colorfly used the flagship series pro-audio series of the famous ALPS volume potentiometer in Japan.
The dust cover and grounding connection were ordered according to the specifications of the Pocket HIFI player.
The rate of the volume error was lower than 5% in average after 1,000 hours. The volume error rates of the C4 was 15% lower than the ALPS official data.

Specific Signal Path
C4 aims to offer hi-fi quality audio from a portable player no larger than the size of a cigarette pack. As such the assembly with circuit board, chips and even the capacitors must be selected very carefully - both for sound and size. Many music players use a signal chip with a main structure made of an MPU, DAC and earphone amplifier. This structure always processed the audio at the cost of great loss with voices sounding stiff, rigid and apathetic. Ever felt fatigue or tired of listening to your normal music player? C4 is the solution.

The internal structure of the C4 is much more complex than traditional MP3 player. In the Pocket HIFI player, the original audio must pass through 8 units from input to output for the sake of getting the perfect voice. Have a look at the diagram on the right to see how much more carefully considered the signal path is in the C4.

Jitter Kill
On the basic of top material and the complex unit designs, the structures which were made of by C4 clock generator, TCXO high-precision crystal Oscillators and the CS8422 SRC chip of CIRRUS output the unbelievable rate of jitter which was lower than 5ps.
The circuit for Jitter Kill has been registered as a patent for the C4 Pocket HIFI player, making this ability quite unique.



The first portable player can drive 300 Ohm or more headphone loads (many customers are successfully using 600 Ohm headphones)
Plays WAV (up to and including 192 kHz / 24bit), FLAC (44.1kHz, 48kHz and 96kHz 16 Bit), OGG Vorbis, APE (44.1kHz and 48kHz 16 Bit) and MP3 (up to 320kbps) files
EQ Function gives you influence on the character of the music playback - customise to your preferences - Normal, Bass, Classical, Rock, Pop, Jazz
Comes with 32GB of Flash Memory built in
Ability to expand memory by adding a micro SD Card (up to 32GB - not supplied) to expand memory to 64GB total
High quality componentry including patented Jitter Kill Technology to improve the music quality
TCXO (Temperature Compensated Crystal Oscillator) to ensure quality - this is the heart of the system, a clock that will help control jitter
Capacitors - one of the most influential components on sound - the C4 features 'Silmic II' capacitors with silk inside from Elna (Japan)
Fader style volume control - quick and easy to use!
Handmade walnut wood and brushed metal surfaces with a somewhat gothic or medieval imagery - certainly looks new and different
Colourfly is a top-flight portable player or even an extension of your hifi system. Look at all the ways you can use it!
Plug in your favourite headphones and use the Colorfly as a high-end portable music source.
Use it as an analogue music source and connect the analogue 6.5mm output directly to your hifi system. (Use an optional adapter cable - stereo 6.5mm to RCA)
As an SP/DIF digital source of music without mechanical vibration caused by moving parts and with a battery power supply.
Acting as a DAC (digital to analogue converter) using the SP/DIF digital input and analog output and up-sampling is also possible.
The Colorfly C4 can be used as a hifi sample rate converter, using the coaxial digital input and then the coaxial digital output. Jitter can be reduced!
Why does it sound so good? The excellent 24 bit / 192kHz (maximum) sound quality is largely due to the single hifi DAC (Digital-to-Analogue Converter) that has been used inside the Pocket Hifi C4. The team who designed the Colorfly Pocket hifi C4 Pro used the CIRRUS logic CS4398, a high-end chipset usually only found in top-of the-range hifi components. This DAC offers outstanding levels of performance with excellent dynamic range up to 120dB and the ability to decode up to 24bit / 192kHz (WAV) audio depending on the format.
