1.  High thrust, can be used for communication, stainless steel
Ultra-class, extra-large cup with small tail
The DC04U is not just an evolution of the DC04PRO, but a complete "Ultra" overhaul. With a powerful 980mW + 980mW@32Ω output, support for 3.5mm microphone calls, and a stainless steel casing, it's packed with features and a superior user experience. The DC04U is essentially a small hexagonal power tail with incredible power and an excellent user experience.
2.  Peak thrust
Little Tail Tier Era
The DC04U requires no external power supply, delivering a continuous and stable output power of up to 980mW + 980mW@32Ω. Driving in-ear headphones? A breeze. Driving over-ear headphones? With ease. Unleash the full potential of all types of headphones without external power. This little power supply is now entering the era of power-level output!

It's not a trick involving external power supply ×
3.  Fully laminated vibrant screen
More colorful user experience
The 0.96-inch fully laminated vibrant screen incorporates dynamic display, perfectly blending a sense of technology with practicality. Three physical buttons on the side offer clear tactile feedback, allowing for easy adjustment of volume, filters, gain, and channel balance—from basic operations to fine-tuning, all can be done with a single button on the device, without relying on a mobile app.
4.  Dual CS43198
Old friends, new surprises
Employing dual CS43198 flagship decoding chips, the DC04U boasts a true balanced four-channel circuitry across the entire decoding process. It supports PCM768/DSD512 hardware decoding and utilizes DRE dynamic enhancement to perfectly resolve 0dB distortion. Leveraging iBasso's years of mature tuning experience, the DC04U fully unleashes the potential of this "old friend": transparent sound, a wide soundstage, and a natural, pleasing listening experience.
5.  FPGA + Femtosecond Crystal Oscillator
Born for HiFi sound quality
Pure sound quality begins with a precise clock. The DC04U uses iBasso's accumulated FPGA audio algorithms, combined with a femtosecond crystal oscillator, to significantly reduce jitter in digital signal transmission through hardware and software clock calibration. This allows the audio signal to be reproduced more closely to the recording state, eliminating interference at the source and presenting a clearer and more natural listening experience.
6.  Independent 4-channel balanced headphone amplifier
Precise adjustments, complete control.
Equipped with an independent 4-channel balanced headphone amplifier circuit, it achieves superior channel separation and power control precision through a refined signal amplification path design. The amplifier power supply ranges from ±4V to ±6V, with precise 0.1V adjustments in each stage, offering greater versatility. It can easily handle both in-ear headphones and over-ear headphones.
7.  Android APK upgrade
It also supports 10-segment PEQ.
Powered by an Android APK, it supports all function settings. Utilizing a high-performance DSP chip, it features 10 built-in EQ presets, each individually configurable and usable to satisfy a wider range of listening preferences. Through iBasso UAC software, it allows for precise 10-band PEQ tuning. Great sound, customizable to your liking!
100 levels of hardware volume control
5 types of digital filtering
3 levels of gain: high, medium, and low.
20-level channel balance adjustment
3 DRE mode options
10-level PEQ with free adjustment
Two types of dynamic/static themes
Two UAC1.0/2.0 protocols
8.  Sound quality dares to compete head-on
The outer shell is also made of hard steel.
The austenitic stainless steel CNC precision-machined shell is far stronger than ordinary aluminum alloy materials, effectively resisting daily bumps and wear. The frame features multi-line cutting and stainless steel brushing; every cut, every polishing and brushing reflects the aesthetic pursuit of mechanical art.
9.  Fully compatible with mobile phones/computers/game consoles
It also supports a 3.5mm microphone.
The DC04U supports seamless switching between UAC2.0 and UAC1.0 protocols, ensuring broad compatibility with multiple device platforms. Its 3.5mm interface also supports SPDIF output and microphone calls.
UAC2.0 mode: can connect to iOS, Android and other mobile phone and tablet devices, and also supports Windows, MAC OS and Linux computer devices.
Scenarios for use with mobile phones or computers
UAC 1.0 Mode: Instantly transforms into an external sound card for game consoles like the Switch 2 and PS5. Game soundtracks have never sounded so clear and beautiful, immersing you in the joy of gaming.
