Our take on the Harman Kardon Onyx

by Ralph Graves
Harman Kardon

Looks and performance — that's what you get with the Harman Kardon Onyx wireless portable speaker system. The elegantly simple design features a brushed aluminum handle that pivots out to become the Onxy's stand. But it's the sound that counts, and that's where the Onyx delivers.

High-performance design

The Onyx has two 3/4" tweeters for detailed highs, and two 3" woofers for clear midrange and bass. Two passive radiators help reinforce the lows — one front-firing, the other rear-firing to ensure solid bass throughout the soundstage. Harman's proprietary digital signal processing ensures accurate, lifelike reproduction of your music.

Bluetooth and Wi-Fi®

The system's built-in Bluetooth lets you wirelessly stream music from your smartphone, tablet, or any other Bluetooth-compatible portable. Whether it's stored music, music services like Pandora® or Spotify, or even video and game soundtracks — if you can hear it through your portable, you can stream it via Bluetooth to the Onyx.

The Onyx also has built-in Wi-Fi, and is DLNA-certified. So you can use your DLNA-compatible AndroidT smartphone, tablet, computer, or other component to stream music and audio to the Onyx. And if you own Apple portables, good news. That Wi-Fi connectivity also lets you use Apple AirPlay through your home network.

Apple AirPlay

Apple AirPlay gives you additional options when you use iTunes® on your computer. Just open iTunes, select the Onyx in the AirPlay menu and start streaming music to the system. Use your iPhone, iPad or iPod touch® to control the iTunes menu on your computer. From your Apple hand-held device., you can stream stored music, video and game soundtracks, and even online music services like Pandora and Spotify.

Portable convenience

You can easily control the Onyx with its touch-sensitive controls. Or use the Harman Kardon's remote app to control the system through your Android or Apple smartphone or tablet. The Onyx's built-in rechargeable battery gives you up to 8 hours of operation. And when its AC adapter is plugged into a wall outlet, you can use the Onyx's USB charging port to keep your portable powered up.

The tweeters, woofers, and one passive radiator is front-firing; the other passive radiator is rear-firing.

Bluetooth Audio Streaming: The Harman/Kardon Onyx supports Bluetooth A2DP wireless audio streaming. This allows you to stream stored music and music apps from your Bluetooth-enabled device (such as your Apple iPod/iPhone/iPad, Android smartphone/table, or computer/laptop) to the Onyx speaker system. You will continue to navigate your music and view song/artist information from your Bluetooth-enabled device.

  • Truesstream Technology: TrueStream technology is Harman's guarantee that you will enjoy the best possible listening experience when you're streaming audio wirelessly via Bluetooth technology. Because you have many options for Bluetooth connectivity, Harman Kardon always use the most current and most advanced option to ensure the highest-quality sound no matter what application or source device you use. Harman Kardon Onyx uses the AAC, aptX and high-bit pool SBC codecs for the best Bluetooth audio from any device.
  • SSP + NFC Pairing: With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled phone to the H/K Onyx without having to enter pin codes or go through complicated settings. Android (OS 4.0+) smartphones that have Near Field Communication (NFC) pair simply by touching the Android device's NFC tag to the speaker system's NFC tag. For older Android smartphones with OS 4.0 or lower, download the NFC Easy Connect app from Google Play to use the head unit's NFC pairing function. Once paired, the Onyx will automatically re-connect with your device when in wireless range (up to 33').
Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the H/K Onyx.

AirPlay Compatible: AirPlay lets you stream music directly from your iPod touch, iPhone, and iPad, or from your iTunes library on your PC or Mac to the Denon Onyx, over your wireless home network connection. By downloading Apple's free Remote App onto your iPod touch, iPhone, or iPad you don't even need to be in the same room as the Onyx or your computer to play, pause, skip, and stop the songs in your iTunes music library. To use the AirPlay feature you need a Mac or Windows-based PC running iTunes (10.1 or later) connected to your wireless home network. Your iPod touch, iPhone, and iPad must have iOS 4.3 or later installed and connected to the same wireless home network.

DLNA Certified: The H/K Onyx is DLNA (Digital Living Network Alliance) certified. This means it's easier for you to access and enjoy digital music stored on your Windows PC, DLNA server, or DLNA-compliant Android device. You'll be able to wirelessly stream your stored music library on your compatible DLNA device to the Onyx speaker. The Onyx supports playback of a variety of music files via DLNA.

Aux Input: In addition to wireless connectivity, the H/K Onyx is fitted with a 3.5mm auxiliary input for connection of almost any portable audio player with a headphone output.

USB Charging Port: The Harman Kardon Onyx is capable of recharging the battery of your mobile device from the speaker's built-in USB (type-A) port. Now you don't need to carry an extra charger to keep your devices powered up. This USB port does not support audio playback.

H/K Remote App: Downloading the free Harman/Kardon Remote app from the iTunes App store onto your Apple iOS (5.0+) device or from the Google Play Store onto your Android (2.2+) device lets you control the Onyx speaker system from your smartphone or tablet device.

To access music apps, you'll need to exit the H/K Remote app and select your desired music app on your iOS or Android device.

Rechargeable Battery: The H/K Onyx has a built-in rechargeable battery that provides up to 6 hours of playback time on a single charge. The battery is easily recharged using the included AC power adapter. The AC power adapter can also be used to power the speaker.

Lots of sound in a small good looking speaker

Written By Anonymous, Fairfax, VA on Monday, April 14, 2014
Crutchfield Customer Review (What's this?)
The sounds that this little speaker can produce is impressive. It is enough to bring an outdoor party to life without the hassle of wires. The setup is easy and well explained. Wifi/Bluetooth sometimes gets interrupted but it is 100ft from the router. Still my other device operate fine at that location so I would have liked a beefier wireless capability. Look is awesome, classy, refined and the handle serves its purpose while contributing to the look. Very good quality and you can feel it. Averall I would recommend it, just be aware that you need a good Wifi signal.
Look, Quality, Sound, Power, Portability
Wifi signal needs to be strong to avoid interruptions
