CrinEar Protocol Micro Ultra-Portable DAC-Amplifier

Inspired by the flagship Protocol Max, the CrinEar Protocol Micro delivers the essential Protocol experience in a streamlined, ultra-affordable package, making high-quality portable audio more accessible than ever.

The Protocol Micro is a compact USB-C to 3.5mm DAC-amplifier that brings high-quality audio and powerful customization to your everyday listening. Built around a modified SPV4040 DAC with an ultra-low output impedance of less than 0.4Ω, it preserves the intended sound of your earphones while delivering clean, transparent playback for music, videos, games, and more. Small enough to fit in any pocket, Protocol Micro is the perfect audio upgrade for smartphones, tablets, and laptops.

What sets the Protocol Micro apart is its built-in 8-band Parametric EQ, allowing you to personalize your listening experience without relying on software during playback. Using the browser-based EQ.Hangout.Audio interface on PC or macOS, you can create and save EQ profiles directly to the device, so your preferred tuning goes wherever the dongle does.
