About Bluetooth® and aptX®
Our Bluetooth products easily connect to any of your devices that have Bluetooth, but to get the best sound possible we recommend using a device that supports Bluetooth aptX. Find out more about aptX here: csr.com/products/aptx
And for iPad or iPhone users that don’t have aptX, don’t despair! MacOS (MacBook, iMac, Mac mini) include Bluetooth aptX, however if you use an iPhone or iPad, Apple generally uses the AAC codec and doesn’t support aptX. AAC sounds really good as well and you'll also get the extra benefit of our upsampling 24-bit DAC, so you won’t be disappointed by the sound quality if you use an iOS device with any of our Bluetooth products.
Left and right speaker included.

HD3: Ultimate mini music system
The ultimate mini music system
Our HD Series was designed for the way people listen to music today— streaming wirelessly, digital downloads, vinyl, etc. HD3 sets a new standard for compact mini music systems because of its versatility and ability to play all of your music from any device.
HD3: No missed connections
Connect to HD3 any way you like: wirelessly or wired, digital or analog. Stream your music library, TIDAL, Spotify, Pandora, YouTube, etc. to HD3 from just about anywhere in your house without dropouts. Wireless setup is a breeze and only takes about a minute. And if you’re using HD3 on your desktop, connect up with a USB cable. The USB input bypasses your computer’s built-in low-quality headphone jack for a high-end listening experience. But if you’re not keen on USB or wireless you can still use any audio cable to connect.
HD3: Your go-to system
Easy setup, simple and useful features, and wide stereo sound make HD3 your go-to music system. HD3 is expandable, so if you want deeper bass just connect up your subwoofer. No matter how you listen to music, HD3 has you covered.
HD3: Plug in your headphones
Plug in your headphones
HD3 includes a dedicated high-performance headphone output so you can listen and not wake the neighbors. Its audiophile-quality headphone amplifier delivers high-end sound that drives even the most-demanding headphones.
HD3 retro-forward design
HD3 was designed for audio performance, but speakers obviously also need to look good so we’ve included furniture-grade wood veneers, aluminum trim accents, and detachable magnetic grills that blend with any decor. Available in Satin Black as well as real Walnut and Cherry wood at no additional cost if you want to really show them off.
HD3: Small speakers that pack a punch
Built-in power amplifiers save space and eliminate the need to connect HD3 to a stereo receiver or external power amp. Simply plug the left speaker into a power outlet and connect the included speaker wire from the left to the right speaker. All internal components of the HD3 are designed and tuned together, so you’ll get Audioengine’s Signature Sound and a much more efficient system than traditional separate speakers and amplifier.

Audioengine designs and manufactures our own speaker drivers and other critical components. In other words, the HD3 is not a “box-built" system with off-the-shelf parts, but includes custom-designed components constructed to our specifications. What we do not fabricate directly inside our factories we have made to our specific designs - parts such as circuit boards, transformers, magnets, and wiring harnesses, for example.
Efficient integrated design
The speaker cabinets, drivers, innovative bass port designs, amplifiers, and passive crossovers are all critically tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components. We build all this goodness into the left speaker cabinet to make it super-easy to connect your smartphone, tablet, computer, TV, network player - or any other audio product.
Built-in B1 and D1
We’ve taken features from two of our best-selling products, the B1 aptX® Bluetooth® Receiver and the D1 24-bit DAC, and combined some of this circuitry with advanced speaker components to achieve a complete high-end analog and digital audio system.
High-quality Bluetooth audio
The Bluetooth built into the HD3 powered speakers features aptX coding which is an advanced Bluetooth audio codec with very impressive sound. And even if your phone or tablet doesn’t have aptX, the HD3 Bluetooth solution is backwards-compatible with SBC and AAC codecs, so you can wirelessly stream music from any Bluetooth-enabled device and still enjoy all your music. High-fidelity Bluetooth aptX that really works and sounds great. Here’s why:
Extended wireless range - Most Bluetooth implementations have very limited range, typically within just one room. But with careful signal management circuitry and antenna tuning, we offer a superior solution that has up to 3 times the range of standard Bluetooth for multi-room use, with no degradation in audio quality.
24-bit DAC - The HD3 Bluetooth receiver and USB input both utilize the AKM AK4396A DAC, widely known for its low-noise and high-fidelity. The AK4396A is used as an upsampling DAC and will pad all bit depths to 24-bits, achieving a higher signal-to-noise ratio and lower noise floor. Due to the high signal-to-noise specs of the AK4396A, the fact that digital signal is upsampled to 24-bits - as well as the added benefit of onboard triple redundancy power source conversion and filtering - the HD3 Bluetooth implementation presents impressive low noise and low distortion characteristics with a noticeable improvement over other Bluetooth devices.
HD3 headphone amplifier
The HD3 contains a high-performance headphone amplifier based on the OPA2134 low-noise opamp. This amp is able to provide low-impedance, high-fidelity audio and a 2-volt output which easily drives a wide range of headphones.
The amplifiers in powered Audioengine speakers are located in the left speaker and are a conservatively-rated class A/B analog monoblock design. This is a more traditional speaker/amplifier configuration which provides excellent quality audio and greater flexibility. All circuit boards for the power and preamp sections are vertically mounted for maximum mechanical shock protection.
Audioengine uses audiophile-quality, ferrofluid-cooled silk dome tweeters with neodymium magnets. Silk tweeters hold up well under high power and the edge-driven design gives very smooth response. The woofers are Kevlar woven glass aramid composite with rubber surrounds. Kevlar is obviously very strong, which means the woofer retains its shape when being driven at high levels.
The HD3 cabinets are available in several handsome finishes, including walnut and cherry veneers as well as satin black paint, offering a wide choice for complementing room furnishings. Also included are detachable grills that add further aesthetic advantages as they are firmly held in place with hidden neodymium magnets for a clean look.
Both of HD3's speaker drivers are directly magnetically-shielded.
