Next-Gen DSP HiFi Evolution
The ST2 PRO Nebula, powered by the custom-designed ES9281AC PRO DAC chip, breaks through the limitations of traditional earphone design and ushers in a new era for HiFi In-ear Monitors. It seamlessly combines a DAC and DSP, providing audiophiles with unparalleled fidelity, convenience, and compatibility.
A Breakthrough in HiFi Audio Technology
Unlike traditional DSP IEMs, the ST2 PRO Nebula integrates a high-performance ESS DAC chip into its design. This USB-C DAC HiFi digital earphone delivers exceptional sound quality in a compact, portable form factor, making it a true game-changer in the audio industry.
ES9281AC PRO: The Core of Superior Sound
The ES9281AC PRO DAC chip, customized for the ST2 PRO Nebula, supports up to 32-bit/384kHz PCM sampling rates and native decoding of DSD128 formats. With ESS's HyperStream® II QUAD DAC™ architecture, it offers superior audio fidelity compared to conventional DSP technologies.
High-End ESS DAC + HiFi Earphones:
An Integrated Solution
By combining the DAC and earphones into one device, the ST2 PRO Nebula eliminates external DAC to earphones, ensuring pure and stable signal transmission. It delivers sound quality on par with traditional DAC and headphone amplifier systems in a simpler, more convenient design.
The earphones support high-resolution audio formats like DSD128 and MQA 8X unfolding, offering a richer, clearer, and more immersive listening experience. From extended highs to deep bass and expressive mid-range, every detail is captured perfectly.
Unlock Hi-Res/MQA Format:
TIDAL, SPOTIFY, Apple Music and Beyond
With its independent decoding chip, the ST2 PRO Nebula supports up to 8X MQA unfolding on platforms like Apple Music, TIDAL, HiBy Music, and Spotify. Experience every lossless detail, surpassing compressed Bluetooth connections like AirPods Pro 2 or other non-HiFi USB-C earphones.
Note: The unfolding factor depends on the playback device, software, and audio file.
Advanced In-Line Control and HD Microphone Support
The ST2 PRO Nebula features in-line controls and a high-definition microphone that converts audio streams to 24-bit/48kHz for crystal-clear voice transmission during calls or gaming. Elevate your on-the-go audio experience effortlessly.
* In-line control and HD microphone are not supported on iPhone Lightning models.
Zero-Latency HiFi: Authentic Audio, No Delay
Designed for zero-latency audio, the ST2 PRO Nebula ensures accurate reproduction of sound with its 20Hz-40kHz frequency response. Whether gaming or streaming, it delivers an immersive experience with a wide soundstage.
Wide Device Compatibility, Including iPhone 15/16 Series
The ST2 PRO Nebula supports most Android devices and is fully compatible with iPhone 15 and 16 models via USB-C, ensuring a plug-and-play experience. Enjoy exceptional sound quality across devices with ease.
Hi-End Professional Cables for Optimal Performance
In addition to the advanced chip, the ST2 PRO Nebula comes with high-purity, oxygen-free copper Hi-End grade professional cables. These cables are wrapped in a woven fiber material for durability and stable signal transmission, ensuring uncompromised audio quality.
Detachable USB-C DSP Earphone Cable for All IEMs
The USB-C DSP Earphone Cable is a game-changer, offering high-performance DAC and DSP technology in a professional-grade cable. Compatible with 0.78mm 2-pin/MMCX IEMs, it delivers up to 70mW+70mW@32Ω, effectively driving most headphones and IEMs. Pair it with your favorite IEMs for a customizable and enhanced listening experience.
