Moondrop ECHO-A Silver Interfață DAC și ADC Hi-Fi

Portable DAC/AMP for High-Resolution Sound Anywhere

The Moondrop ECHO-A is a high-resolution portable DAC/AMP that turns any USB-C device into a serious music source. Plug it into a smartphone, laptop, or tablet and the dongle takes over decoding and amplification, replacing the often mediocre output of built-in audio circuitry. Hardware-level processing handles PCM streams up to 32-bit/384kHz, so high-resolution tracks play back with the detail and dynamic range the files were mastered for. This dongle is the right choice for listeners who want a clean, low-noise upgrade to mobile audio without carrying a desktop stack.

What Sets the ECHO-A Apart

At the heart sits a dedicated audio SoC that integrates a CPU, RAM, DSP, and decoding amplifier on a single chip — a level of integration rarely seen at this price tier. The 3.5mm output is a 4-pin OMTP-standard jack, carrying both the headphone signal and an online-controlled microphone line for headsets with inline mics. Running over the UAC 2.0 protocol means no drivers, apps, or firmware updates are needed across Windows, macOS, Android, and iOS.

Technical Performance That Matters

Measured figures put this dongle comfortably in audiophile territory, with headroom to drive sensitive in-ear monitors without adding hiss to the background.

• Sample Rate / Bit Depth: 384 kHz / 32 bit — hardware-level decoding for lossless and high-resolution PCM files.
• Signal-to-Noise Ratio: 100 dB (A-weighted) — clean output that stays quiet even with sensitive IEMs.
• Dynamic Range: 102 dB (A-weighted) — preserves the contrast between quiet and loud passages in well-mastered music.
• THD+N: 0.01% (AES17, 20 kHz, no-load) — vanishingly low distortion so the amplifier adds nothing of its own to the signal.
• Output Jack — a 3.5mm 4-Pin (SE + MIC / OMTP) socket that carries both the headphone signal and an online-controlled microphone line for headsets with inline mics.

Who Should Pick Up the ECHO-A

This dongle is built for listeners who already own good headphones or in-ear monitors and want to unlock their potential from a phone or laptop. It suits commuters, students, and remote workers who need a discreet upgrade that slips into a pocket without adding weight. Casual gamers benefit from the OMTP microphone pass-through, which keeps a headset's inline mic working for voice chat on mobile and desktop. Anyone whose device has dropped the headphone jack — or whose built-in output sounds flat and noisy — will hear an immediate improvement in clarity, bass control, and overall musicality.
