Audioengine HD4 Wireless Speaker System (Walnut)

HD4 HOME MUSIC SYSTEM W/ BLUETOOTH APTX-HD

Effortlessly fill any living space with the power of
incredible, true stereo sound that brings your listening experience to life. 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, or good old analog from that vintage turntable or
prized tape deck.

MADE FOR YOUR MUSIC

INSPIRED BY THE WAY YOU LISTEN

Rounding out Audioengine’s legacy HD-series, HD4 wireless
speakers offer versatile, high-fidelity audio ideal for smaller spaces. A
premium-powered, two-speaker setup that offers excellent music reproduction and
surrounds you with a sense of presence that most 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.

PLAY YOUR MUSIC, YOUR WAY

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, or good old analog from that
vintage 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.

BOLD DESIGN THAT FITS IN

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.
