Overview
The details behind EarAcoustic OSHUN DECO.
EarAcoustic Balance — Unveiling the True Pulse of Sound
OSHUN DECO "SHUN Resolution" is a decoding dongle featuring a built-in CB5100PRO USB audio bridge chip, dual low-power high-performance CS43198 DAC chips, and dual SGM8262 high-fidelity headphone amplifier chips. Paired with OSHUN earphones, it forms an outstanding full-power direct-drive flagship system with speaker-like sound. The module offers excellent compatibility with mainstream systems, including Android, HarmonyOS, Windows 10/11, iOS, and macOS, delivering high-resolution audio across virtually any platform.
Dual-DAC & Dual-AMP Architecture
Equipped with flagship dual CS43198 DAC chips and dual SGM8262 amplifiers, OSHUN DECO builds a fully balanced audio matrix. It supports hardware decoding of PCM 768kHz/32-bit and DSD256, handling high-end Hi-Res sources with ease. Beyond USB-IIS/DoP audio bridging, the CB5100PRO further integrates a high-performance DSP, ADC, and PGA, supporting flexible 10-band EQ configuration that greatly enriches and enhances the use cases and experience of EarAcoustic Audio earphones.
10-Band EQ to Freely Define Your Sound
Say no to one-size-fits-all "standard sound." Through the WALK PLAY app, you can fine-tune the 10-band EQ and adjust the frequency response curve as you like. It also supports EQ linkage in the app, so you can take your personalized timbre with you wherever you go. With ultra-fine resolution and composed, relaxed dynamic control, OSHUN DECO brings emotional detail to your earphones — it is not just a DAC/amp, but a master of sonic aesthetics in the palm of your hand. Note: EQ tuning is only supported on Android and HarmonyOS.
Simple Connection, Compatible Across Ecosystems
Plug and play. OSHUN DECO comes with mainstream dual outputs — 3.5mm single-ended and 4.4mm balanced — and is fully compatible with Android, HarmonyOS, iOS, Windows, and macOS. It breaks system barriers so good sound is no longer limited by platform. A built-in smart detection circuit automatically identifies 3-pole and 4-pole headphone plugs, eliminating tedious setup. The 4.4mm balanced port delivers up to 551.25mW of output power, while the 3.5mm single-ended output provides 151.25mW.
Sculpted Tech-Metal Aesthetics
The entire unit is made of aluminum alloy with full-CNC precision machining and polished through multiple processes. The body combines a fine matte finish with a high-gloss mirrored grid pattern, showing a balance of toughness and elegance as light moves across the surface. In use, the RGB sample-rate indicator changes color with the source quality — ice blue for standby, green for 88.2k/96k, blue for 176.4k/198k, red for above 352.8k, and white for DSD.
Pitch-Black Background Comes from Clean Power
Inside, SHUN Resolution uses multiple ultra-low-noise power chips. They protect weak audio signals while building a stable, clean power supply, effectively suppressing the noise floor so music emerges from a deep background with clear contours and rich layers. With adaptive load support from 16Ω to 600Ω, OSHUN DECO drives high-sensitivity balanced-armature and large dynamic-driver headphones with ease, delivering a pure, immersive listening experience across all compatible gear.
