The Story

The AUDIOCULAR Note Hi-Res Portable DAC Dongle is a next-generation digital-to-analogue converter and headphone amplifier engineered for audiophiles who demand uncompromised sound quality on the go. Built around the KT02H20 high-performance DAC chipset paired with the OPA97220 precision headphone amplifier, the NOTE delivers true high-resolution audio with exceptional clarity, dynamic range, and ultra-low distortion.

Featuring dual headphone outputs—4.4mm balanced and 3.5mm single-ended— it provides impressive driving power for both sensitive IEMs and demanding full-size headphones. With PCM decoding up to 32-bit/384kHz, it reproduces music with studio-grade detail, accurate imaging, and a clean, natural sound signature ideal for critical listening.

Designed for universal plug-and-play compatibility, the NOTE works seamlessly with Android, iOS, Windows, macOS, and HarmonyOS without requiring drivers. Its refined audio circuitry, optimized power management, and ultra-low THD+N performance ensure a distortion-free listening experience with a 100dB signal-to-noise ratio and -90dB crosstalk suppression (balanced).

With support for the My AUDIOCULAR App, users get access to 5-band PEQ and a built-in community preset ecosystem for sharing and discovering custom sound tunings.

Crafted from a premium all-aluminum alloy chassis, the NOTE combines durability, heat dissipation, and a sleek minimalist finish in a compact and highly portable form factor—perfect for everyday audiophile listening anywhere, anytime.
