About iBasso DC04 Ultra
The iBasso DC04 Ultra brings exceptional audio processing to your portable setup. Dual Cirrus Logic CS43198 DAC chips handle the signal with precision while support for PCM up to 32-bit 768 kHz and native DSD512 delivers rich detail in every track. The custom FPGA+ algorithm keeps everything synchronized so you enjoy smooth playback without timing issues. This combination lets you hear subtle nuances that elevate your listening sessions.
Powerful amplification drives even demanding headphones with ease. The fully balanced 4-channel architecture produces up to 980 mW per channel into 32 ohms on the balanced output and includes both 4.4 mm balanced and 3.5 mm single-ended ports. Output impedance remains below 0.1 ohms which preserves clarity and control across different loads. You gain the headroom needed for dynamic music without strain.
A practical interface enhances daily use. The 0.96-inch multi-color OLED display shows essential information at a glance while 10-band parametric EQ through the app lets you fine-tune the sound to your preference. Microphone support on the 3.5 mm port adds convenience for calls during commutes or travel. These elements make the device feel intuitive rather than complicated.
Solid construction pairs with wide compatibility. The stainless steel chassis provides reliable durability in a compact package that travels effortlessly. It works seamlessly with Android, iOS, Windows, macOS, Linux, and popular gaming consoles through UAC 1.0 and UAC 2.0 protocols. You can switch devices without hassle and maintain high performance everywhere.
Performance metrics confirm its reference-level capability. Ultra-low distortion at 0.00011 percent combines with a 132 dB dynamic range and strong channel separation for transparent sound. Frequency response extends from 10 Hz to 80 kHz with tight accuracy so bass stays impactful and highs remain smooth. This portable DAC and amp turns any compatible source into a high-end audio experience.

Reviews
Sound quality blew me away right from the first track. The power handles my full-size headphones without any effort and the details come through so clearly. I love adjusting the EQ on my phone during walks.
Compact size fits perfectly in my pocket for daily commuting. The balanced output gives my IEMs extra clarity and the display makes volume checks quick. Battery drain on my phone stays reasonable even with longer sessions.
Switching between my laptop and phone works smoothly with no setup hassle. The microphone support lets me take calls without unplugging and the overall build feels solid. Great upgrade for my audio setup.
