INSPIRED BY THE WAY YOU LISTEN
Rounding out Audioengine’s legacy HD-series, the HD4 wireless home music system offers versatile, high-fidelity audio ideal for smaller spaces. The HD4 system offers excellent music reproduction and surrounds you with a sense of presence that compact systems often miss.

Bringing home the high-performance technology inside our HD6 along with the convenience of our modestly-sized HD3, the HD4 is a perfect blend of the power you love to feel and the modern functionality you depend on. Thoughtfully wrapped in precision-tuned, hand-built wood-veneer cabinets.

CONNECT TO YOUR MUSIC NO MATTER WHERE IT LIVES
An all-access pass to ALL of your music on any app or device, the HD4 offers wired or wireless connections including USB input from your computer, Bluetooth aptX-HD from your phone, tablet or computer, or good old analog from that turntable or prized tape deck.

Featuring Bluetooth aptX-HD for premium, extended-range wireless that allows for quick and easy connection to stream your existing music services, tune into your favorite podcast or listen to those carefully curated playlists from your personal music library.

Your music, your way. Anywhere you want to listen. It’s that simple.

VERSATILE, SIZE-DEFYING SOUND
Designed to take on space limitations, the HD4 is the perfect upgrade where surfaces are minimal but performance and convenience can’t be compromised. As handsome as they are compact, the HD4 will easily fit in any small living space and blend in with any decor.

Purpose-built for versatility, the HD4’s modest design does little to prepare listeners for such expansive soundstage and crystal-clear imaging. The difference between listening to your music and hearing ALL of it...with more room for dancing.
