This article covers 【国内正規品】Audioengine オーディオエンジン HD3 ワイヤレス・パワードスピーカー (ブラック).

Overview

The Audioengine HD3 is a compact powered speaker system that has become a staple in desktop audio. It features a 2.75-inch Kevlar woofer and a 3/4-inch silk dome tweeter, delivering a total maximum output of 60W (15W RMS per channel) via a Class AB amplifier. Bluetooth wireless connectivity is built-in, allowing easy streaming from smartphones and tablets.
The left speaker houses the amplifier and connects to the right speaker via the included 16AWG speaker cable. The black finish gives it a premium look that blends into any desk setup.

Connectivity & Compatibility

The HD3 offers versatile input options: one RCA pair and one 3.5mm mini-jack input on the rear panel. These allow wired connection to PCs, DACs, game consoles, and more. Bluetooth supports aptX for high-quality wireless audio from mobile devices.
Power is supplied via the included AC adapter (100-240V). There is no USB input, so a separate DAC is needed for USB audio from a computer. The right speaker connects to the left with the provided speaker cable.

Market positioning: a bridge between entry-level and high-end desktop audio. It offers a balanced combination of sound quality, design, and longevity.

Best Use Cases

    Less ideal for:
  • Budget-focused buyers: There are more feature-rich options at this price.
