Overview
The details behind SIMGOT DEW4 Ultra.
Dual CS43198 DAC & Dual SGM8262 Amplifier Architecture
The DEW4 Ultra features dual CS43198 DAC chips, delivering powerful performance and excellent musicality. With a 131dB wide dynamic range, it restores detail and dynamics for a more realistic and expressive sound. It supports 768kHz/32bit PCM and DSD256 high-resolution audio, easily decoding various sources. The carefully designed peripheral filter circuit suppresses power noise and interference, ensuring a pure and stable audio signal. Two independent SGM8262 amplifier chips handle left and right channel signal amplification separately, greatly reducing crosstalk and ensuring cleaner output.
Pitch-Black Background with 131dB SNR
Through meticulous circuit design, the DEW4 Ultra achieves an astonishingly low noise floor. It delivers a 131dB signal-to-noise ratio and ultra-low distortion of <0.00018% (@4.4mm BAL). This allows sound to emerge from a pitch-black background with an almost "0" noise floor (1μVrms). The pure sonic background fully presents instrumental overtones, spatial reverberation, and sound layers. In gaming scenarios, it helps reveal subtle audio details such as footsteps, weapon switching, and environmental interactions, giving you a competitive edge.
Professional Gaming Presets Co-Tuned with Pro Players
SIMGOT collaborated with professional players and veteran gamers from different game genres to develop and tune game sound effects based on real battle scenarios. For popular games such as APEX, Delta Force, VALORANT, and CS2, the tuning focuses on optimizing key information like footsteps, gunshots, weapon switching, and environmental interactions. The APP and web platform include multiple official game EQ presets, allowing one-click loading without manual parameter adjustment. The internal testing team continuously optimizes official presets based on test results and user feedback.
Versatile Outputs with High/Low Gain Adjustment
The DEW4 Ultra supports both 3.5mm single-ended and 4.4mm fully balanced output modes. A manual gain switch lets you easily select the appropriate gain mode based on your headphone's characteristics or personal preference, adapting to more scenarios and devices. The 3.5mm single-ended output delivers 126mW@32Ω, while the 4.4mm balanced output reaches 501mW@32Ω. It also features 30-level stepped volume control with differentiated steps across volume ranges, and volume settings are retained after power-off.
All-Platform Compatibility with UAC1.0/2.0
One device meets the needs of mobile listening, desktop audio, and console gaming. It supports UAC 1.0 and UAC 2.0, allowing driver-free connection to Switch, PS5 series, and other gaming consoles. It is also compatible with mainstream systems including Android, iOS, iPadOS, macOS, and Windows, ensuring smooth transitions between music, video, and gaming across different devices. The Type-C output port is compatible with phones, PCs, laptops, PS5, Xbox, Switch, and more, while supporting high-fidelity audio transmission.
Visual DSP Tuning & Premium Build
The DEW4 Ultra supports a visual DSP tuning platform with 10-band PEQ, allowing independent control of center frequency, Q value, and gain, with multiple configuration profiles. The EQ cloud community supports sharing and downloading presets. It also offers five digital filter modes — FAST-LL, FAST-PC, SLOW-LL, SLOW-PC, and NON-OS — and adjustable microphone gain via the APP or web platform. It comes standard with an 8-strand single-crystal copper silver-plated cable and a Type-C to USB-A adapter. The full aluminum CNC-machined chassis offers durability and premium aesthetics.
Note: Due to MFi certification, the iOS version of the SIMGOT Control APP cannot adjust DAC settings. iOS users can use a Mac or Windows computer to access the web-based tuning platform and apply EQ settings, which are then retained when connected to iOS devices.
