The most compact generation
The Eye series DAC & headphone amplifiers are designed withconnecting cables, featuring interfaces on both ends and pursuingan
extremely symmetrical product style,Eye3 is the third-generation wired DAC product, embodyingfunctional integration aesthetics
through its exquisite designDespite incorporating a 3.5mm/4.4mm jack, a USB-C port,a DAC and amplification motherboard,
and three additionacontrol buttons, its final size is wat+wabout as large as a thumbrepresenting a 20% reduction in volume
compared to the previousgeneration. This achieves a breakthrough in portability while
expanding interface and functionality options,
The Energy Paradoxin a Compact Form
The Eye3 packs immense power into its pocket-sized body.Driven by dual SMG8262-2 high-power amplifier chips at its core,
it delivers an impressive 510mW output.enough to effortlesslydrive even some popular over-ear headphones,
creating a strikingcontrast between its compact size and formidable power.
This embodies a unique aesthetic of contrast between form andperformance.
A Masterpiece of Performanceand Energy Efficiency Balance
The Cirrus Logic CS43198 DAC chip redefines the audio experience
with its multidimensional technological advantages. Equipped with ahigh dynamic range architecture
and low-distortion circuit design,complemented by high channe isolation,
it ensures pristine soundquality from the source. In terms of format compatibilityit supports high sample rate decoding,
native DSD processing, andseamless format switching, adapting to diverse audio scenarios.Furthermore, t
he integration of advanced filtering technology anda low-power architecture balances performance
and energyefficiency, providing a core solution for portable audio devices,
Expanded Connectivity-Dual 3.5mm + 4.4mm Ports
The TC44Pro E3 features an integrated dual-port design withboth 3.5mm and 4.4mm outputs,
offering greater flexibility forheadphone pairing.In balanced decoding scenarios, the 4.4mminterface
stands out as the preferred choice, delivering powerfuldrive and refined audio performance. Meanwhile,
the return ofthe 3.5mm jack ensures compatibility not only with traditionaearphones but also with instruments
and audio equipment,broadening its application range. Through an optimized spatiallayout,
the new design achieves a more compact form factodespite the additional port,
perfectly balancing functionalexpansion and portability.
Independent VolumeControl & Gain Switch
Designed with ergonomics in mind, the Eye3 features three front-fac-ing buttons that allow for effortless one-handedoperation.
The volume up/down buttons are intuitively sized for easyblind adjustment, while the less frequently used gain switch isstrategically
placed at a slight distance to prevent accidental toggling
Button Operations
Volume Buttons (Volume +/-),Short press repeatedly, adjust thevolume. The maximum volume level is 60.Gain Switch,Short press once to
turn on,Short press again to turnoff.The yellow indicator light on the back will illuminate when highgain is active.
Indicator Lights
The Eye3's indicator lights are positioned on the back to preventdiscomfort from direct light exposure during nighttime use.
The PCM/DSD indicator features two colors:
Blue: represents PCM decoding output.
Green: indicates native DSD decoding* output.
The GAlN indicator lights up yellow to signify high-gain mode.
*When playing DSD files on an Android phone, first enable USBexclusive mode in the app, then set the DSD output to "Native.
