QCC5124 Quad-Core Processors
QCC5124 architecture is engineered for high performance with low power consumption. Power consumption can be reduced by up to 65 per cent compared to our previous technology for both voice calls and music streaming, and devices are optimized to support longer audio playback in virtually all operating modes.

ES9219 x 2
The ES9219 SABRE HiFi SoC delivers audiophile-grade sound quality and output power, allowing the ES9219 to drive the most demanding headsets and provide a real line-level output to match professional audio equipment. The heart of the ES9219 ESS's award-winning SABRE DAC technology, with a HyperStream II modulator. This is the same architecture that is used in the world's finest audiophile equipment.

High-quality Bluetooth codecs
5K supports the latest high-quality audio codecs, including aptX Adaptive, SONY LDAC, and AAC. Android 8.0 or higher supports LDAC by default. *iOS works with Bluetooth AAC 260kbps.

2.5mm BALANCED 4VRMS
Balanced: Always Better
Within any given audio system, the Balanced provides higher output power, better linearity, and lower noise than the Unbalanced. To the 2.5mm output, 5K works with Dual ES9219 DAC/AMP. *You will need to replace the existing 3.5mm UNBAL cable with 2.5mm BAL cable.

3.5mm UNBALANCED 2VRMS
To the 3.5mm output, 5K works with Single ES9219 DAC/AMP. The ES9219 SABRE HiFi SoC delivers audiophile-grade sound quality and 2VRMS output power, allowing the ES9219 to drive the most demanding headsets and provide a real line-level output to match professional audio equipment.

Automatic Battery Care
5K manages the battery for maximum life cycle, not for the time. Furthermore, 5K draws its system power directly from USB when working as a USB DAC. In other words, 5K does NOT draw any power from the battery when charging. It helps keep the battery life longer, and it ensures the same battery charging time even while streaming audio.

10-Band Pro-Grade Equalizer
The embedded pro-grade equalizer is a vital benefit of 5K DAC/AMP over other similar products. It processes every incoming source of audio from everywhere: Youtube, Apple Music, Spotify, iOS, Android, PC, Bluetooth(all Codecs), and USB. For more degree of freedom, 5K DAC/AMP supports parametric EQ in addition to graphical EQ. The embedded DSP cores perform double-precision 64-bit EQ processing, providing accurate and precise frequency response.

2-Way Associative Absolute Volume
5K always delivers the optimal Sound Quality, whatever source or device volume levels are. Any source volume level or device volume level will eventually control the 5K built-in Hybrid Volume System, keeping the source audio's original bit-resolution. No need to keep the smartphone volume or PC USB volume at the maximum anymore for the optimal Sound Quality. Adjust volume whatever comfortable way you like it.

iOS/Android App
5K Mobile App enables the user to access every detail; Battery history, charger status, volume, DAC operating profile, DAC LPF filter, Equalizer, USB DAC sample rate, microphone gain, Bluetooth codecs.

*5K is the only Bluetooth device that displays real-time LDAC bitrate.

Silicon MEMS Oscillator
The built-in MEMS audio clock helps ES9219 D/A Conversion perform its best. Silicon is inherently more reliable than quartz. MEMS OSC also provides 3000 times better Vibration Robustness than quartz OSC.

3-D LDS Antenna
5K delivers the optimal RF performance with high Sensitivity 3-dimensional LDS(Laser Direct Structuring) Antenna. The antenna is printed on the bottom case around the Red LED button.
